Episode Date
The Science & Treatment of Obsessive-Compulsive Disorder (OCD) | Episode 78
9215
In this episode, I explain the biology and psychology of obsessive-compulsive disorder (OCD)—a prevalent and debilitating condition. I also discuss the efficacy and mechanisms behind OCD treatments—both behavioral and pharmacologic as well as holistic and combination treatments and new emerging treatments, including directed brain stimulation. I explain the neural circuitry underlying repetitive “thought-action loops” and why in OCD, the compulsive actions merely make the obsessions even stronger. I review cognitive-behavioral therapies like exposure therapy and SSRIs, holistic approaches, and nutraceuticals, detailing the efficacy of each approach and what science says about how to combine and sequence treatments. I describe an often effective approach for treating OCD where clinicians use cognitive behavioral therapy (CBT) to deliberately bring patients into states of high anxiety while encouraging them to suppress compulsive actions in order to help them learn to overcome repetitious thought/action cycles. This episode should interest anyone with OCD, anyone who knows someone with OCD or OCPD, and more generally, those interested in how the brain works to control thoughts and actions, whether those thoughts are intrusive or not.

Ido Portal: The Science & Practice of Movement | Huberman Lab Episode 77
9277
My guest is Ido Portal, the world’s foremost expert on human movement. Ido has spent a lifetime studying, combining and evolving elements from an enormous range of martial arts, dance genres, athletic endeavors, and science, to develop a unified theory and practice of movement called “The Ido Portal Method.” Here we discuss all things movement, including the role of the nervous system, reflexive versus deliberate movement patterns, and the link between emotions and awareness in movement. We also discuss learning and neuroplasticity, the mind-body connection and how movement itself can be leveraged toward expanding other types of skills- cognitive, creative and otherwise. As one of the most sought out teachers of movement alive today, the knowledge Ido shares in this conversation can benefit everyone—children, adults, athletes, dancers, clinicians and trainers and the everyday person.

Improve Flexibility with Research-Supported Stretching Protocols | Episode 76
7569
In this episode, I explain the science behind limb range of motion and flexibility and how to increase them by using science-supported protocols. Flexibility is crucial for physical movements and can help prevent injuries, decrease inflammation, modulate physical and mental pain, impact exercise recovery speed and even potentially slow the progression of certain diseases. I explain the biology of flexibility, including the specific neural mechanisms that sense stretch and load (i.e., tension) on the muscles and limbs, as well as how specific brain regions like the insula combine those signals to ultimately control limb range of movement. I also provide science-based stretching and “micro-stretching” protocols that reliably improve limb flexibility with the minimum necessary time investment. I review all the details of those stretching protocols: how often to do them, for how long, their timing relative to other exercises, sets, the time between sets, measuring progress and more. All people, physically active or not, should benefit from the information and tools described in this episode.

The Science & Process of Healing from Grief | Episode 74
7607
This episode, I discuss grief and the challenges of processing losses of different kinds. I explain the biological mechanisms of grief, including how neural circuits for emotional and factual memory combine with those for love and attachment, to create feelings of absence and yearning. I discuss how grief is distinct from depression, yet why they can feel so similar. I also provide science-based tools to assist with the grieving process, including how to reframe and remap the relationship with those we have lost while still maintaining a strong emotional connection to them. I also explain the importance of having and building strong foundational psychological and biological states so that we can better cope with grief when it happens. Finally, I describe tools to adjust those states, including those for accessing sleep, managing stress and emotional swings. This episode is for those suffering from grief but also for everyone, given that we all experience grief at some point in our lives. We recorded this episode before the recent mass shooting tragedies in the United States. While we hope the information in this episode will be of use to anyone suffering from grief of any kind and at any time, we are also careful to acknowledge that many people require additional support and resources. For that reason, we include mention of such resources and we generally hope people will access them if needed.

Understand & Improve Memory Using Science-Based Tools | Episode 72
7756
This episode I explain the mechanisms by which different types of memories are established in our brain and how to leverage the amount and timing of key neurochemicals and hormones, such as adrenaline (aka epinephrine) and cortisol, to improve your learning and memory abilities. I describe multiple science-based protocols to do this, including repetition, caffeine, emotional states, deliberate cold exposure, sleep, meditation, and the role of vision, including taking “mental snapshots.” I also describe how exercise and an associated hormone, osteocalcin, can improve cognitive ability and memory formation. I also describe unique aspects and forms of memory such as photographic memory, extreme facial recognition (aka super recognition), and the phenomenon known as déjà vu.

Understanding & Controlling Aggression | Episode 71
5453
This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones—estrogen and testosterone—in mediating violent and and/or competive aggression. I also describe tools that can be used to modulate the factors that have been shown to ‘prime’ an individual for aggression, including sunlight, estrogen sensitivity, competition within social settings, and overall stress levels, and the hormone cortisol. I discuss how substances such as caffeine and alcohol can impact impulsive behaviors, and how nutrition and supplementation can be used to regulate mood and aggression.  Thank you to our sponsors AG1 (Athletic Greens): https://athleticgreens.com/huberman ROKA: https://www.roka.com -- code: huberman Helix Sleep: https://www.helixsleep.com/huberman See Andrew Huberman Live: The Brain Body Contract https://hubermanlab.com/tour Our Patreon page https://www.patreon.com/andrewhuberman Supplements from Momentous https://www.livemomentous.com/huberman.

The Science & Health Benefits of Deliberate Heat Exposure | Episode 69
6790
I describe the mechanisms by which deliberate heat exposure impacts body temperature, metabolism, heart health, hormone production, exercise recovery, cognition, mood, and longevity. I detail specific protocols for deliberate heat exposure, including exposure times, temperature ranges to consider, time of day, and delivery mechanisms (sauna vs. hot bath vs. open air heat, etc.) in order to achieve different specific outcomes, including dramatic growth hormone releases, or reduction in cortisol levels. I also discuss the ability of locally applied heat to heal or otherwise improve various bodily tissues and new data on how local application of heat may induce the conversion of metabolically sluggish white fat to metabolically robust beige fat.

Using Salt to Optimize Mental & Physical Performance | Episode 63
7433
I discuss the role of salt (sodium) in the nervous system and the key role that it plays in mental performance, physical performance and health. I explain how the brain senses salt levels in our body and how that relates to our feelings of thirst. I cover the physiology of the renal system and the hormones that control sodium and water balance in our body. I also explore how salt interacts with stress and our immune systems and its crucial role in neuron function. Additionally, I examine research findings suggesting that some individuals might benefit from increased intake of sodium and other electrolytes (magnesium and potassium) to enhance mental performance, lessen anxiety, and offset dizziness. Yet, other people may need less sodium. I discuss how you can determine your optimal sodium intake and why sodium intake levels need to be uniquely tailored to an individual’s lifestyle. Finally, I explain how salt creates ‘hidden’ sugars in many processed foods and the problems that can create. Throughout the episode, I explain peer-reviewed findings outlining salt’s essential role in overall health and describe general recommendations and tools anyone can use to find their optimal salt balance and thereby enhance their brain and body’s performance.

Dr. Justin Sonnenburg: How to Build, Maintain & Repair Gut Health | Episode 62
8078
My guest this episode is Dr. Justin Sonnenburg, Professor of Microbiology & Immunology at Stanford University. Dr. Sonnenburg’s research focuses on how microbes in our gut impact our mental and physical health and how diet and your environment shape your gut microbiome. We discuss the architecture of the gut microbiome and microbiota variability in different regions of the gastrointestinal (GI) tract and how these can change in response to diet, environment or genetics. We explore the early establishment of your microbiome and how your mode of delivery into the world (C-section or not) shapes your gut. We also discuss lifestyle factors that can alter your microbiome and the integral role the gut microbiome plays in communicating to other organs, including your brain. Dr. Sonnenburg details his recent clinical study, which found that diets rich in fermented foods (but not fiber) increase microbiota diversity and reduce signals of inflammation. Additionally, we examine how foods typical in Western Diets (e.g., high fat, low fiber, processed foods) can negatively impact the gut microbiome. Throughout the episode, we discuss actionable tools from peer-reviewed clinical findings that anyone can implement, regardless of budget, in order to optimize their gut microbiome and health.

How to Enhance Your Gut Microbiome for Brain & Overall Health | Episode 61
6734
In this episode, I discuss the profound effect the gut has on the nervous system. I cover the structure and function of the gut-brain axis and the role of the gut microbiome in the brain and overall health. I describe how the gut controls hunger or satiety by affecting neurons in our brain. I also contrast the many pathways by which the gut influences the brain: direct vs. indirect pathways, chemical vs. mechanical, and fast vs. slow signaling. Additionally, I discuss what defines a healthy microbiome and how your lifestyle impacts the gut microbiome, including the effects of stress, fasting, antibiotics, pets, environment, prebiotics and probiotics. I address how different foods shape the gut microbiome, in particular, the emerging data that fermented foods can increase the diversity of healthy gut microbiota. Throughout the episode, I explain peer-reviewed and textbook findings that reveal the critical role of the gut microbiome in supporting mental and physical health and I outline simple tools that anyone can use in order to enhance their gut microbiome health.

Using Play to Rewire & Improve Your Brain | Episode 58
6395
In this episode, I discuss the transformative nature of play—how it changes our feelings, thoughts and actions and indeed, how it can rewire our brain to function better in all contexts. I explain the role of play in childhood, as well as adulthood in skill and social development and describe key characteristics of the mind and body during play. Additionally, I explore how play allows the brain to test contingencies in different roles/environments. Throughout, I discuss the underlying neurobiology of play. I also describe how low-stakes play, and tinkering can broaden and shape your future capabilities. Finally, I discuss how our childhood ‘personal play identity’ informs our adult personality. Throughout the episode, I use the science of play to outline recommendations for using play as a means to enhance neuroplasticity and explore novel situations, regardless of age.

Dr. Alia Crum: Science of Mindsets for Health & Performance | Episode 56
6062
My guest is Dr. Alia Crum, Associate (tenured) Professor of Psychology at Stanford University and Director of the Stanford Mind & Body Lab. Dr. Crum is a world expert on mindsets and beliefs and how they shape our responses to stress, exercise, and even to the foods we eat. We discuss how our mindset about the nutritional content of food changes whether it is satisfying to us at a physiological (hormonal and metabolic) level. She also tells how mindsets about exercise can dramatically alter the effects of exercise on weight loss, blood pressure, and other health metrics. Dr. Crum teaches us how to think about stress in ways that allow stress to grow us and bring out our best rather than diminish our health and performance. Throughout the episode, Dr. Crum provides descriptions of high-quality peer-reviewed scientific findings that we can all leverage toward better health and performance in our lives.

The Science of Setting & Achieving Goals | Episode 55
6862
In this episode, I discuss the science of setting, assessing, and pursuing goals. I explain the neural (brain) circuits that underlie goal setting and pursuit. Then I describe nine science-supported tools anyone can apply toward their goals. I explain when and how to use goal visualization, when to use multitasking and how to use specific rewards to improve the likelihood of reaching your goals. I also explain why envisioning failures and their consequences are effective and how to set goals of the appropriate level of challenge. I also explain how the molecule dopamine is used to gauge our progress toward milestones and long-term overarching goals and how to leverage dopamine for goal pursuit. Finally, I explain a unique tool called 'space-time bridging' that can be used to support all aspects of goal setting, assessment, and pursuit. This episode ought to be useful for anyone seeking to improve their performance in work, school, exercise, athletics, or personal development.

Dr. Jack Feldman: Breathing for Mental & Physical Health & Performance | Episode 54
8616
This episode my guest is Dr. Jack Feldman, Distinguished Professor of Neurobiology at the University of California, Los Angeles and a pioneering world expert in the science of respiration (breathing). We discuss how and why humans breathe the way we do, the function of the diaphragm and how it serves to increase oxygenation of the brain and body. We discuss how breathing influences mental state, fear, memory, reaction time, and more. And we discuss specific breathing protocols such as box-breathing, cyclic hyperventilation (similar to Wim Hof breathing), nasal versus mouth breathing, unilateral breathing, and how these each affect the brain and body. We discuss physiological sighs, peptides expressed by specific neurons controlling breathing, and magnesium compounds that can improve cognitive ability and how they work. This conversation serves as a sort of "Master Class" on the science of breathing and breathing-related tools for health and performance.   Thank you to our sponsors: Thesis - https://takethesis.com/huberman  Athletic Greens - https://www.athleticgreens.com/huberman  Headspace - https://www.headspace.com/specialoffer    Our Breath Collective: http://www.ourbreathcollective.com/huberman    Dr. Jack Feldman Links: UCLA website - https://bioscience.ucla.edu/people/jack-feldman Wikipedia - https://en.wikipedia.org/wiki/Jack_L._Feldman Twitter - https://twitter.com/prebotzinger Instagram - https://www.instagram.com/jacklfeldman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Introducing Dr. Jack Feldman 00:03:05 Sponsors: Thesis, Athletic Greens, Headspace, Our Breath Collective 00:10:35 Why We Breathe  00:14:35 Neural Control of Breathing: “Pre-Botzinger Complex” 00:16:20 Nose vs Mouth Breathing 00:18:18 Skeletal vs. Smooth Muscles: Diaphragm, Intracostals & Airway Muscles 00:20:11 Two Breathing Oscillators: Pre-Botzinger Complex & Parafacial Nucleus 00:26:20 How We Breathe Is Special (Compared to Non-Mammals) 00:33:40 Stomach & Chest Movements During Breathing 00:36:23 Physiological Sighs, Alveoli Re-Filling, Bombesin 00:49:39 If We Don’t Sigh, Our Lung (& General) Health Suffers 01:00:42 Breathing, Brain States & Emotions  01:05:34 Meditating Mice, Eliminating Fear  01:11:00 Brain States, Amygdala, Locked-In Syndrome, Laughing 01:16:25 Facial Expressions 01:19:00 Locus Coeruleus & Alertness 01:29:40 Breath Holds, Apnea, Episodic Hypoxia, Hypercapnia 01:35:22 Stroke, Muscle Strength, TBI 01:38:08 Cyclic Hyperventilation 01:39:50 Hyperbaric Chambers 01:40:41 Nasal Breathing, Memory, Right vs. Left Nostril 01:44:50 Breathing Coordinates Everything: Reaction Time, Fear, etc. 01:57:13 Dr. Feldman’s Breathwork Protocols, Post-Lunch  02:02:05 Deliberately Variable Breathwork: The Feldman Protocol 02:06:29 Magnesium Threonate & Cognition & Memory  02:18:27 Gratitude for Dr. Feldman’s Highly Impactful Work 02:20:53 Zero-Cost Support, Sponsors, Patreon, Instagram, Twitter, Thorne Title Card Photo Credit: Mike Blabac Disclaimer

The Science of Making & Breaking Habits | Episode 53
6638
In this episode, I review the science of habit formation and habit elimination and how the process of neuroplasticity (brain rewiring) underlies these processes. I describe two new systems for habit formation. The first system is grounded in the neuroscience of brain states and our ability to perform (and to avoid) certain tasks at different phases of the 24-hour day. The second system focuses on 21-day habit formation and consolidation. I also discuss "task bracketing" as an approach to enhancing habit formation and eliminating unwanted habits and the neural circuits that underlie task bracketing in the basal ganglia (a brain region for generating and stopping behaviors). I also review the science of dopamine rewards and how to apply that knowledge to shaping habits. The science and tools in this episode ought to be helpful for anyone looking to build better habits and eliminate unwanted habits for school, work, fitness, relationships, creative endeavors, and more—indeed for any person or situation where behavioral changes are needed.   Thank you to our sponsors: Athletic Greens - http://www.athleticgreens.com/huberman  InsideTracker - http://www.insidetracker.com/huberman  Helix Sleep - http://www.helixsleep.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: Excellent review on science of habits - https://www.annualreviews.org/doi/abs/10.1146/annurev-psych-122414-033417  Meta-analysis on habits - https://journals.sagepub.com/doi/full/10.1177/1539449219876877    Timestamps: 00:00:00 Introducing Habits; New Programs 00:02:30 Athletic Greens, InsideTracker, Helix Sleep 00:06:52 Habits versus Reflexes, Learning, Neuroplasticity 00:08:51 Goal-Based Habits vs. Identity-Based Habits 00:11:40 How Long It (Really) Takes to Form a Habit; Limbic-Friction 00:16:07 Linchpin Habits  00:18:55 Mapping Your Habits; Habit Strength, Context-Dependence 00:22:55 Automaticity 00:24:03 Tool 1: Applying Procedural Memory Visualizations 00:27:48 Hebbian Learning, NMDA receptors 00:31:00 Tool 2: Task Bracketing; Dorsolateral Striatum 00:37:08 States of Mind, Not Scheduling Time Predicts Habit Strength 00:38:16 Tool 3: Phase-Based Habit Plan: Phase 1 00:46:29 Tool 3: Phase-Based Habit Plan: Phase 2 00:55:24 Tool 3: Phase-Based Habit Plan: Phase 3 01:01:34 Habit Flexibility 01:04:57 Should We Reward Ourselves?

Dr. David Sinclair: The Biology of Slowing & Reversing Aging | Episode 52
7842
In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don't Have To, and the host of the Lifespan Podcast, which launches January 5, 2022.  In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology. This episode includes lots of basic science and specific, actionable protocols, right down to the details of what to do and when. By the end, you will have in-depth knowledge of the biology of aging and how to offset it.   Thank you to our sponsors: ROKA - https://www.roka.com - code "huberman" InsideTracker - https://www.insidetracker.com/huberman Magic Spoon - https://www.magicspoon.com/huberman   Dr. David Sinclair Links: Lifespan Podcast: https://lifespanpodcast.com  Twitter: https://twitter.com/davidasinclair Instagram: https://www.instagram.com/davidsinclairphd/   YouTube: https://www.youtube.com/davidsinclairpodcast   Lifespan (book): https://amzn.to/3mAZQjF  Aging Test Waitlist: https://www.doctorsinclair.com   Harvard Lab Website: https://sinclair.hms.harvard.edu    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Dr. David Sinclair, Harvard Medical School 00:03:30 ROKA, InsideTracker, Magic Spoon 00:07:45 “Aging as a Disease” vs. Longevity & Anti-Aging 00:10:23 What Causes Aging?

Science of Social Bonding in Family, Friendship & Romantic Love | Episode 51
5601
This episode I discuss the science of social bonding- the process by which we form attachments. I explain the neural and hormonal basis for "social homeostasis" (our drive for a given amount of socializing) which reveals why we get lonely, why we seek out connection with others and how power dynamics (hierarchies) shape those connections. I also discuss the neurochemical basis of introversion and extroversion, of trust and how shared experiences that promote similar physiological states in two or more individuals, leads to more rapid bonding. I also discuss how food and oxytocin play key roles in social bonding. This episode covers quality peer-reviewed science and practical tools for anyone seeking to find, build or end relationships.   Thank you to our sponsors: ROKA - https://www.roka.com - code "huberman" Athletic Greens - https://www.athleticgreens.com/huberman Headspace - https://www.headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Social Bonding: Child-Parent, Romantic, Friendship, Breakups 00:02:55 ROKA, Athletic Greens, Headspace 00:07:08 Social Bonding as a Biological Process 00:10:03 Social Isolation 00:13:32 Social Homeostasis & Neural Circuits for Social Drive  00:18:55 Brain Areas & (Neuro)Chemistry of Social Drive  00:22:48 What is Social Homeostasis & Dopamine 00:27:00 When We Lack Social Interactions: Short- Versus Long-Term 00:28:10 Introverts & Extroverts 00:31:00 “Good” Versus “Bad” Social Interactions & Hierarchies 00:33:54 Loneliness & Dorsal Raphe Nucleus & Social Hunger  00:37:33 Tools 00:38:05 Socializing & Food Appetite: Crossover Craving 00:42:45 Falling in Love 00:45:05 Tools for Social Bonds: Merging Physiologies; Story 00:53:54 Childhood Attachment Patterns in Adulthood 01:03:45 Attachment Styles: Autonomic Versus Intellectual Attachment 01:06:10 Emotional Empathy & Cognitive Empathy, Arguing 01:09:45 Allan N.

Dr. David Berson: Understanding Your Brain's Logic & Function | Episode 50
6767
In this episode, my guest is Dr. David Berson, Professor & Chairman of Neuroscience at Brown University. Dr. Berson discovered the neurons in your eye that set your biological rhythms for sleep, wakefulness, mood and appetite. He is also a world-renowned teacher of basic and advanced neuroscience, having taught thousands of university lectures on this topic. Many of his students have become world-leading neuroscientists and teachers themselves.  Here Dr. Berson takes us on a structured journey into and around the nervous system, explaining: how we perceive the world and our internal landscape, how we balance, see, and remember. Also, how we learn and perform reflexive and deliberate actions, how we visualize and imagine in our mind, and how the various circuits of the brain coordinate all these incredible feats.  We discuss practical and real-life examples of neural circuit function across the lifespan. Dr. Berson gives us a masterclass in the nervous system—one that, in just less than two hours, will teach you an entire course's worth about the brain and how yours works.   Thank you to our sponsors: Athletic Greens - https://athleticgreens.com/huberman  InsideTracker - https://insidetracker.com/huberman  Magic Spoon - https://magicspoon.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: InsideTracker Interview - https://blog.insidetracker.com/longevity-by-design-andrew-huberman  Dr. Berson's Webpage -  https://vivo.brown.edu/display/dberson  Eyewire - (Contribute to Neuroscience Research from Home/Computer - https://eyewire.org/explore   Best Neuroscience Textbook (NOTE this is a TEXTBOOK) - https://amzn.to/3lZWrL4  Book - We Know It When We See It by Richard Masland - https://amzn.to/31S60Vp    Timestamps: 00:00:00 Dr. David Berson  00:02:55 Sponsors: Athletic Greens, InsideTracker, Magic Spoon  00:08:02 How We See  00:10:02 Color Vision  00:13:47 “Strange” Vision 00:16:56 How You Orient In Time 00:25:45 Body Rhythms, Pineal function, Light & Melatonin, Blueblockers 00:34:45 Spending Times Outdoors Improves Eyesight  00:36:20 Sensation, Mood, & Self-Image 00:41:03 Sense of Balance 00:50:43 Why Pigeons Bob Their Heads, Motion Sickness  01:00:03 Popping Ears 01:02:35 Midbrain & Blindsight  01:10:44 Why Tilted Motion Feels Good  01:13:24 Reflexes vs. Deliberate Actions 01:16:35 Basal Ganglia & the “2 Marshmallow Test” 01:24:40 Suppressing Reflexes: Cortex  01:33:33 Neuroplasticity  01:36:27 What is a Connectome? 01:45:20 How to Learn (More About the Brain) 01:49:04 Book Suggestion, my Berson Appreciation 01:50:20 Zero-Cost ways to Support the HLP, Guest Suggestions, Sponsors, Patreon, Thorne   Please note that The Huberman Lab Podcast is distinct from Dr. Huberman's teaching and research roles at Stanford University School of Medicine.

Erasing Fears & Traumas Based on the Modern Neuroscience of Fear | Episode 49
8029
In this episode, I discuss fear and trauma, including the neural circuits involved in the "threat reflex" and how specific experiences and memories come to activate that system. I also discuss how our body is involved in trauma and fear. First, I describe the logic of fear mechanisms and how "top-down" processing-- meaning connections from the parts of the brain that assign meaning to our feelings, are involved in fear and erasing fears and traumas. Then I discuss what successful fear and trauma treatment must include and consider various treatments for whether they meet that standard, such as EMDR, Cognitive Behavioral Therapy, Ketamine, other drug-assisted therapies, and more. I also review new data on how 5 minutes per day of deliberate, self-imposed stress can erase fear and depression. And I review the role that social connection plays in erasing or maintaining fears by activating specific molecular pathways in the brain and body. Finally, I review supplementation with over-the-counter compounds for their effects on anxiety and fear and when to take them, if at all.   Thank you to our sponsors: Athletic Greens - https://www.athleticgreens.com/huberman  InsideTracker - https://www.insidetracker.com/huberman  Helix Sleep - https://www.helixsleep.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: https://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Introducing Fear, Trauma & Trauma  00:02:15 Athletic Greens, InsideTracker, Helix Sleep 00:06:49 What is Fear?  00:11:45 Autonomic Arousal: “Alertness” vs. “Calmness” 00:13:44 Hypothalamic-Pituitary-Adrenal Axis (HPA axis) 00:17:36 “The Threat Reflex”: Neural Circuits for Fear 00:28:24 Controlling Fear: Top-Down Processing 00:32:27 Narratives: “Protective or Dangerous” 00:35:58 Attaching Fear to Events: Classical Conditioning & Memory 00:41:45 How Fear Learning Occurs: Long Term Potentiation, NMDA 00:46:10 Extinguishing (Reducing) Fears 00:50:25 Cognitive (Narrative) Therapies for Fear 00:57:56 Repetition of Narrative, Overwriting Bad Experiences with Good 01:05:28 EMDR: Eye Movement Desensitization Reprocessing 01:14:00 Social Connection & Isolation Are Chemically Powerful 01:18:23 Trans-Generational Trauma 01:25:00 PTSD Treatments: Ketamine, MDMA, oxytocin 01:39:25 How Do You Know If You Are Traumatized?  01:46:16 Deliberate Brief Stress Can Erase Fears & Trauma 01:49:50 Erasing Fears & Traumas In 5 Minutes Per Day 01:59:42 Nutrition, Sleep, & Other General Support Erasing Fear & Trauma 02:02:30 Supplements for Anxiety, Fear: Saffron, Inositol, Kava 02:10:00 Synthesis  02:11:46 Zero-Cost Support, Sponsors, Patreon, Supplements, Instagram, Twitter   Please note that The Huberman Lab Podcast is distinct from Dr. Huberman's teaching and research roles at Stanford University School of Medicine.

Dr. David Buss: How Humans Select & Keep Romantic Partners in Short & Long Term | Episode 48
7982
In this episode, my guest is Dr. David Buss, Professor of Psychology at the University of Texas, Austin, and one of the founding members of the field of evolutionary psychology. Dr. Buss describes his work on how people select mates for short and long-term relationships, the dynamics of human courtship, and mate value assessment — meaning how people measure up as potential partners. We also discuss the causes of infidelity and differences for infidelity in men and women. He explains how people evaluate and try to alter other people’s mate value as a means to secure and even poach mates. We discuss monogamous and non-monogamous relationships in humans. And we discuss what Dr. Buss calls “the dark triad”— features common in stalkers and narcissists that relate to sexual and psychological violence in relationships. This episode is sure to be of interest to anyone single or in a relationship who seeks to know how people select mates and anyone who is interested in forming and maintaining healthy romantic partnerships.   Thank you to our sponsors: ROKA - https://www.roka.com - code "huberman" InsideTracker - https://www.insidetracker.com/huberman  Headspace - https://www.headspace.com/specialoffer    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: https://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: Dr. Buss' New Book "When Men Behave Badly" - https://amzn.to/3FThTsG  Dr. Buss' Website at University of Texas, Austin - https://labs.la.utexas.edu/buss/david-buss/  Dr. Buss' Twitter - https://twitter.com/ProfDavidBuss    Timestamps: 00:00:00 Introducing Dr. David Buss 00:04:10 Sponsors: ROKA, InsideTracker, Headspace 00:08:33 Choosing a Mate 00:13:40 Long Term Mates: Universal Desires 00:18:31 What Women & Men Seek in Long-Term Mates 00:25:10 Age Differences & Mating History  00:32:20 Deception in Courtship 00:37:30 Emotional Stability 00:38:40 Lying About Long-Term Interest 00:41:56 Short-Term Mating Criteria, Sliding Standards & Context Effects 00:46:25 Sexual Infidelity: Variety Seeking & (Un)happiness & Mate Switching 00:54:25 Genetic Cuckolds, How Ovulation Impacts Mate Preference 00:57:00 Long-Term vs. Short-Term Cheating, Concealment 00:59:15 Emotional & Financial Infidelity 01:04:35 Contraception  01:06:22 Status & Mating Success 01:10:10 Jealousy, Mate Value Discrepancies, Vigilance, Violence 01:24:13 Specificity of Intimate Partner Violence   01:25:12 Mate Retention Tactics: Denigration, Guilt, Etc. 01:27:33 Narcissism, Machiavellianism, Psychopathy 01:33:25 Stalking 01:39:15 Influence of Children on Mate Value Assessments  01:43:24 Attachment Styles, Mate Choice & Infidelity 01:46:40 Non-Monogamy, Unconventional Relationships   01:54:00 Mate Value Self Evaluation, Anxiety About the Truth 02:02:12 Self Deception 02:05:35 The Future of Evolutionary Psychology & Neuroscience   02:06:56 Books: When Men Behave Badly; The Evolution of Desire, Textbooks 02:10:42 Concluding Statements, Zero-Cost Support: Subscribe, Sponsors, Patreon, Thorne   Please note that The Huberman Lab Podcast is distinct from Dr. Huberman's teaching and research roles at Stanford University School of Medicine.

The Science of Gratitude & How to Build a Gratitude Practice | Episode 47
5156
In this episode, I discuss the science of gratitude, which has been shown in peer-reviewed studies to have tremendous positive effects on mental and physical health. I explain, however, that most commonly used gratitude practices are ineffective (such as gratitude lists). The key elements of highly effective gratitude practices are described, including the essential need for story (narrative), receiving or perceiving gratitude rather than giving it, and the role that theory of mind plays in this context. I also discuss why we can't simply make up feelings of gratitude and how reluctance undermines the process. I also explain the neural circuit mechanisms that underlie the reductions in fear and increases in motivation and lowering of inflammatory chemicals that effective narrative-based gratitude can trigger. Throughout the episode, I use the science of gratitude to design a brief but highly effective protocol.    Thank you to our sponsors: ROKA - https://www.roka.com - code "huberman" InsideTracker - https://www.insidetracker.com/huberman  Magic Spoon - https://www.magicspoon.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: https://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: Neural Correlates of Gratitude (Damasio) - https://bit.ly/3oS8TNr  Reducing Inflammatory Cytokines & Fear With Gratitude - https://bit.ly/3oPsSwv    Timestamps: 00:00:00 Introduction: Gratitude Science & Surprises 00:01:50 Controlling Heart Rate with Story 00:04:33 Sponsors: ROKA, InsideTracker, Magic Spoon 00:09:11 Major, Long-Lasting Benefits of Gratitude Practice 00:12:20 Prosocial vs. Defensive Thinking, Behaviors, & Neural Circuits  00:17:50 Why We All Need an Effective Gratitude Practice 00:21:22 Neurochemistry & Neural Circuits of Gratitude 00:25:10 Prefrontal Cortex Set Context 00:30:10 Ineffective Gratitude Practices; Autonomic Variables 00:34:55 Key Features of Effective Gratitude Practices: Receiving Thanks & Story 00:42:30 Theory of Mind Is Key 00:45:50 Building Effective Gratitude Practices: Adopting Narratives, Duration 00:52:28 Narratives That Shift Brain-Body Circuits  00:56:15 You Can’t Lie About Liking Something; Reluctance In Giving 00:59:55 How Gratitude Changes Your Brain: Reduces Anxiety, Increases Motivation 01:03:00 5 Minutes (Is More Than Enough), 3X Weekly, Timing Each Day  01:05:44 Empathy & Anterior Cingulate Cortex 01:07:35 Reducing Inflammation & Fear with Gratitude 01:10:56 Serotonin, Kanna/Zembrin  01:16:00 Neuroplasticity, Pharmacology, Brain Machine Interfaces 01:18:50 The Best Gratitude Practices: & How To, My Protocol 01:24:25 Subscribe & Feedback, Supporting Sponsors, Supplements (Thorne)

Time Perception & Entrainment by Dopamine, Serotonin & Hormones | Episode 46
4456
In this episode, I discuss how our brain and body track time and the role that neurochemicals, in particular dopamine and serotonin, but also hormones such as melatonin, allow us to orient ourselves in time. I review the three types of time perception: of the past, of the present, and the future, and how dopamine and serotonin adjust both our perception of the speed of the passage of time and our memory of how long previous experiences lasted. I also discuss circannual entrainment, which is the process by which our brain and body are matched to the seasons, and circadian (24 hours) entrainment, both of which subconsciously adjust our perceived measurement of time. I explain the mechanisms of that subconscious control. And I cover the ultradian (90 minutes) rhythms that govern our ability to focus, including how to track when these 90-minute rhythms begin and end for the sake of work and productivity. I include ten tools based on the science of time perception that you can apply to enhance productivity, creativity, and relationships in various contexts.    Thank you to our sponsors: ROKA - https://www.roka.com - code "huberman" Athletic Greens - https://www.athleticgreens.com/huberman  InsideTracker - https://www.insidetracker.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Introducing Time Perception, Note on Fasting & Supplements 00:05:12 Sponsors: ROKA, Athletic Greens, InsideTracker 00:09:25 Entrainment, Circannual Entrainment, Melatonin 00:13:20 Seasonal Oscillations in Testosterone & Estrogen, Tool 1 00:16:06 Circadian Timing, Tools 1, 2, 3 (for Circadian Entrainment) 00:21:13 Tool 4: Timing Physical Activity; Tool 5: Timing Eating Window 00:23:00 When Circadian Entrainment is Disrupted, Time Perception Suffers 00:25:00 Tool 6: Ultradian (90min) Cycles & Focus 00:31:42 Our Sense of the Passage of Time: Present, Prospective, Retrospective 00:34:40 Dopamine (& Nor/epinephrine) Lead to Time Overestimation; Frame Rate  00:37:18 Serotonin & Time Underestimation; Decreased Frame Rate 00:39:10 Dopamine vs. Serotonin Across the Day; Tool 7: When to Do Rigid vs. Creative Work 00:42:38 Example of Tool 7 00:43:38 How Sleep Deprivation Degrades Performance 00:44:38 Trauma, “Over-clocking” & Memories; Adjusting Rates of Experience 00:50:04 Why Trauma Involves Dopamine & Epinephrine, Arousal 00:51:03 Dopamine, Spontaneous Blinking & Time Perception; Tool 8 00:53:38 Deliberate Cold Exposure, Dopamine, Tool 9: Adjusting Frame Rate in Discomfort 00:56:30 Fun “Feels Fast” BUT Is Remembered as Slow; Boring Stuff “Feels Slow,” Recall As Fast 01:00:54 Retrospective Time, Context Variation & Enhanced Bonding with Places & People 01:03:00 Dopamine Release Resets the Start of Each Time Bin on Our Experience 01:07:40 Habits & Time Perception; Tool 10 (Setting Functional Units of Each Day) 01:11:58 Synthesis & Book Suggestion (Your Brain Is a Time Machine by D.

Dr. Duncan French: How to Exercise for Strength Gains & Hormone Optimization | Episode 45
5405
In this episode, I talk to Dr. Duncan French, Ph.D., the Vice President of Performance at the UFC Performance Institute and a world-class performance specialist. We discuss specific resistance (weight) training regimens for increasing testosterone in men and women and how to vary mechanical loads and rest between sets and workouts to optimize hormone output and training results. We also discuss how stress-induced "catecholamines" can increase testosterone or decrease it, depending on duration and mindset.

Using Your Nervous System to Enhance Your Immune System | Episode 44
7231
This episode teaches you a lot about the immune system, immune-brain interactions and offers 12 potential tools for enhancing immune system function. I discuss how our immune system works and science-supported tools we can use to enhance our immune system. I discuss the innate and adaptive immune systems and our various microbiomes-- not just in our gut but also in our nose, eyes and mouth and how to keep them healthy. And I review how specific patterns of breathing and foods maintain a healthy mucosal barrier that is crucial for fighting infections. I discuss how certain neurochemicals called catecholamines enhance our immune system function and how to use specific breathing protocols, types and timing of heat and cold exposure, and, if appropriate, supplementation to activate catecholamines. I also discuss the role and use of serotonin for the sake of accessing the specific types of sleep for recovering from illness, and I discuss how to increase glymphatic "washout" of brain debris during sleep. I also review fever, the vagus nerve and the use of atypical yet highly effective compounds for rhinitis (nasal inflammation).

Dr. Samer Hattar: Timing Your Light, Food, & Exercise for Optimal Sleep, Energy & Mood | Episode 43
8067
In this episode, I host Dr. Samer Hattar, Chief of the Section on Light and Circadian Rhythms at the National Institute of Mental Health. Dr. Hattar is a world-renowned expert on how viewing light at particular times adjusts our mood, ability to learn, stress and hormone levels, appetite, and mental health. We discuss how to determine and use your individual light sensitivity to determine the optimal sleep-wake cycle for you. We also discuss how to combine your light viewing and waking time with the timing of your food intake and exercise in order to maximize mental and physical functioning. Dr. Hattar is credited with co-discovering the neurons in the eye that set our circadian clocks and regulate mood and appetite. He explains why even a small shift in daylight savings leads to outsized effects on our biking because of the way that our cells and circadian clocks integrate across many days. And he offers precise tools to rapidly adjust to jetlag, shift work, and reset your clock after a late night of work or socializing. This episode is filled with cutting-edge data on the biological mechanisms of human physiology and practical tools for people of all ages.    Thank you to our sponsors: ROKA - https://www.roka.com -- code: "huberman" InsideTracker - https://www.insidetracker.com/huberman  Magic Spoon - https://www.magicspoon.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Samer Hattar: Twitter Instagram Wikipedia   Links: Graphical Explanation of Temperature Minimum for Overcoming Jetlag   Timestamps: 00:00:00 Introducing Dr. Samer Hattar, Ph.D. 00:02:17 Sponsors: ROKA, InsideTracker, Magic Spoon 00:06:15 Light, Circadian (24 hour) & Circannual (365 day) “Photoentrainment”  00:14:30 Neurons in Our Eyes That Set Our Body Clocks: Similar to Frog Skin 00:18:55 What Blind People See  00:20:15 When, How & How Long to View Light for Optimal Sleep & Wakefulness 00:30:20 Sunlight Simulators, Afternoon Light Viewing, Naps 00:33:48 Are You Jetlagged at Home?

Nutrients For Brain Health & Performance | Episode 42
6078
This episode I describe science-supported nutrients for brain and performance (cognition) and for nervous system health generally. I describe 10 tools for this purpose, including specific amounts and sources for Omega-3 fatty acids which make up the "structural fat" of neurons (nerve cells) and allow them to function across our lifespan. I also review data on creatine, phosphatidylserine, anthocyanins, choline, glutamine and how they each impact brain function in healthy people seeking to reinforce and improve their cognition and in those combatting cognitive decline. I describe both food-based and supplement-based sources for these compounds, and their effective dose ranges based on peer-reviewed literature. Then I review the 3 factors: gut-brain signaling, perceived taste, and learned associations that combine with the metabolic and blood-sugar-elevating effects of food to determine what foods we seek and prefer. Amazingly, it's not just about what tastes good to us. Next, I explore how we can leverage the neural circuits of learned food preference toward seeking and enjoying the right foods for brain health and performance. I also review new data on non-caloric sweeteners and why consuming them with glucose-elevating foods can be detrimental, in some cases rapidly leading to insulin dysregulation. This episode covers more than 10 actionable tools for those seeking to improve and/or maintain brain function, and it explains modern neuroscience underlying of our sense of taste, our food seeking preferences and brain metabolism.   Thank you to our sponsors: ROKA - https://www.roka.com -- code: "huberman" InsideTracker - https://www.insidetracker.com/huberman Headspace - https://www.headspace.com/specialoffer    RETHINK EDUCATION: The Biology of Learning Featuring Dr. Andrew Huberman: https://youtu.be/Oo7hQapFe3M    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Links: Review on Anthocyanins and Cognition Review on Creatine & Brain Health Studies  Review on "Rethinking Food Reward"    Timestamps: 00:00:00 Food & Brain Function Introduction 00:02:08 Summary: Critical Aspects of Time Restricted Feeding/Fasting 00:04:19 Sponsors: ROKA, Athletic Greens, Headspace 00:08:24 Neuroplasticity Super Protocol (Zero-Cost Tools) Online 00:09:22 Eating to Enhance Brain Function & Foundational Aspects of Brain Health  00:13:00 Eating Fats for Brain Health, EFAs Phospholipids (Tool 1: 1-3g EPA Omega-3/day)  00:20:35 Phosphatidylserine (Tool 2: 300mg/day) 00:22:15 Choline, Egg Yolks (Tool 3: 1-2g/day Threshold) 00:28:26 Hydration & Electrolytes (Tool 4) 00:29:50 Liquid Fish Oil/Capsules (2-3g EPA per day; 300mg Alpha GPC 2-4X/week) 00:32:22 Creatine for Cognition (Tool 5: 5g/day)  00:36:28 Anthocyanins, Dark Skin Berries (Tool 6-10mg/day (Extract), 1-2 cups Berries)  00:41:19 L-Glutamine (Tool: 1-10g/day) & Offsetting Apnea & Inflammation 00:49:23 Neural Basis of Food Preference, Yum, Yuck, Meh; Taste, Guts, & Beliefs 00:55:25 Taste is 100% In your Head 00:59:50 Gut Neurons Controlling Food Preference: Neuropod Cells; (Tool 7: Fermented Foods)  01:06:14 Capsule Probiotics, Brain Fog  01:07:16 Learning to Like Specific Tastes: Sweetness & Brain Metabolism 01:12:11 Hard-Wiring & Soft-Wiring 01:13:25 Artificial & Non-Caloric Sweeteners: Safe or Harmful Depends on (Glucose) Context 01:18:15 Non-Caloric Sweetener & Insulin; (Tool 8: Don’t Have w/Glucose Elevating Foods) 01:22:17 Beliefs & Thoughts; The Insula; (Tool 9: Pairing-Based Reshaping Food Preferences)  01:30:42 Liking Neuro-Healthy Foods & Bettering Brain Metabolism (Tool 10); Food Wars 01:36:05 Food Reward & Diabetes, Obesity; Important Review Article (See Caption) 01:38:28 Synthesis, Zero-Cost Support, Future Topic Suggestions, Sponsors, Supplements

Effects of Fasting & Time Restricted Eating on Fat Loss & Health | Episode 41
8766
This episode I discuss the science and practice of fasting also called time-restricted feeding. I review the data on how limiting food intake to specific portions of every 24-hour cycle (or fasting longer) impacts weight loss, fat loss specifically, liver health, mental focus, muscle, longevity and more. I explain how "fasted" is contextual, and relates to blood glucose levels and their downstream effects, and how the depth of fasting can be adjusted with behaviors such as different types of exercise, or with glucose disposal agents. I also discuss the optimal fasting protocol: and both the absolute (non-negotiable) and variable (contextual) features of a fasting/time-restricted-feeding protocol that will allow you to get the most benefits. I also discuss what does and does not break a fast, the effects of fasting on hormones like testosterone and cortisol and on fertility. I also review how different feeding windows of 8 or 10 or 4 hours differentially impact the effects of fasting, and why the classic 8 hour feeding window came to be but also might be ideal. I discuss mechanisms and offer tools to discern the optimal fasting duration and timing for you.   Thank you to our sponsors: ROKA - https://www.roka.com -- code: "huberman" InsideTracker - https://www.insidetracker.com/huberman Helix Sleep - https://www.helixsleep.com/huberman    RETHINK EDUCATION: The Biology of Learning Featuring Dr. Andrew Huberman https://youtu.be/Oo7hQapFe3M   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com Newsletter - https://hubermanlab.com/neural-network    Links: Comprehensive Review On Fasting In Humans: https://bit.ly/3BwIyd7   Timestamps: 00:00:00 Introduction, Blood Glucose & Mortality, Mice Vs.

Dr. Craig Heller: Using Temperature To Optimize Performance, Brain & Body Health | Episode 40
6695
This episode I am joined by Dr. Craig Heller, Professor of Biology at Stanford University and world expert on the science of temperature regulation. We discuss how the body and brain maintain temperature under different conditions and how most everyone uses the wrong approach to cool off or heat up. Dr. Heller teaches us the best ways and in doing so, explains how to offset hyperthermia and hypothermia. He also explains how we can use the precise timing and location of cooling on our body to greatly enhance endurance and weight training performance. He describes how cooling technology discovered and engineered in his laboratory has led to a tripling of anaerobic (weight training) performance and allowed endurance athletes to run further and faster, as well as to eliminate delayed onset muscle soreness. Dr. Heller explains how heat impairs muscular and mental performance, and how to cool the brain to reduce inflammation and to enhance sleep and cognition. We discuss how anyone can apply these principles for themselves, even their dogs! Our conversation includes both many practical tools and mechanistic science.   Thank you to our sponsors: ROKA - https://www.roka.com -- code "huberman" InsideTracker - https://www.insidetracker.com/huberman Athletic Greens - https://www.athleticgreens.com/huberman   Support Research in Huberman Lab at Stanford: https://hubermanlab.stanford.edu/giving   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman    Links: Dr. Heller's Website - https://profiles.stanford.edu/h-craig-heller CoolMitt Technology - https://www.coolmitt.com  Timestamps: 00:00:00 Introducing Dr. Craig Heller, Physiology & Performance 00:02:00 Sponsors: Roka, Inside Tracker, Athletic Greens 00:06:45 Cold Showers, Ice Baths, Cryotherapy 00:10:45 Boundary Layers  00:11:55 Cooling Before Aerobic Activity to Enhance Performance 00:14:45 Anaerobic Activity Locally Increases Muscle Heat 00:16:45 Temperature Gates Our Energy Use  00:19:00 Local Versus Systemic Fatigue: Heat Is Why We Fail 00:22:10 Cooling Off: Most Methods are Counterproductive 00:26:43 Exercise-Induced Brain Fog 00:27:45 Hyperthermia 00:31:50 Best Body Sites for Cooling: Palms, Foot Pads, Upper Face  00:38:00 Cooling Your Brain via The Upper Face; Concussion 00:41:25 Extraordinary (Tripling!)

Controlling Your Dopamine For Motivation, Focus & Satisfaction | Episode 39
8191
This episode serves as a sort of “Dopamine Masterclass”. I discuss the immensely powerful chemical that we all make in our brain and body: dopamine. I describe what it does and the neural circuits involved. I explain dopamine peaks and baselines, and the cell biology of dopamine depletion. I include 14 tools for how to control your dopamine release for sake of motivation, focus, avoiding and combating addiction and depression, and I explain why dopamine stacking with chemicals and behaviors inevitably leads to states of underwhelm and poor performance. I explain how to achieve sustained increases in baseline dopamine, compounds that injure and protect dopamine neurons including caffeine from specific sources. I describe non-prescription supplements for increasing dopamine—both their benefits and risks—and synergy of pro-dopamine supplements with those that increase acetylcholine.    Thank you to our sponsors: ROKA - https://www.roka.com -- code "huberman" InsideTracker - https://www.insidetracker.com/huberman  Headspace - https://www.headspace.com/specialoffer    Logitech Event - Rethink Education: The Biology of Learning Thursday, Sept. 30 at 12pm PT / 3pm ET Sign up here: https://info.logitech.com/ReThink-Education.html    Support Research in Huberman Lab at Stanford: https://hubermanlab.stanford.edu/giving   Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Links: Review on Dopamine: https://www.nature.com/articles/s41583-021-00455-7 Cold Exposure & Dopamine: https://link.springer.com/article/10.1007%2Fs004210050065    Timestamps: 00:00:00 Introduction & Tool 1 to Induce Lasting Dopamine 00:04:48 Sponsors: Roka, InsideTracker, Headspace 00:09:10 Upcoming (Zero-Cost) Neuroplasticity Seminar for Educators 00:09:58 What Dopamine (Really) Does 00:15:30 Two Main Neural Circuits for Dopamine  00:18:14 How Dopamine Is Released: Locally and Broadly 00:22:03 Fast and Slow Effects of Dopamine 00:25:03 Dopamine Neurons Co-Release Glutamate 00:28:00 Your Dopamine History Really Matters  00:30:30 Parkinson’s & Drugs That Kill Dopamine Neurons.

Dr. Matthew Johnson: Psychedelics for Treating Mental Disorders | Episode 38
10324
This episode I discuss medical research on psychedelic compounds with Dr. Matthew Johnson, Professor of Psychiatry and Behavioral Sciences at Johns Hopkins School of Medicine. We discuss the biology and medical clinical-trial uses of psilocybin, MDMA, ayahuasca, DMT, and LSD. Dr. Johnson teaches us what the clinical trials in his lab are revealing about the potential these compounds hold for the treatment of depression, addiction, trauma, eating disorders, ADHD, and other disorders of the mind. Dr. Johnson describes a typical psychedelic experiment in his laboratory, start to finish, including the conditions for optimal clinical outcomes. And he explains some of the potential hazards and common misconceptions and pitfalls related to psychedelic medicine. Dr. Johnson explains flashbacks, the heightened risks of certain people and age groups using psychedelics and the ever evolving legal and pharmaceutical industry landscape surrounding psychedelics. Dr. Johnson also explains how the scientific study of psychedelics is likely to set the trajectory of psychiatric medicine in the years to come. Dr. Johnson is among a small handful of researchers who have pioneered the clinical study of these powerful compounds.

ADHD & How Anyone Can Improve Their Focus | Episode 37
8280
In this episode, I discuss ADHD (Attention-Deficit Hyperactivity Disorder): what it is, the common myths, and the biology and psychology of ADHD. I discuss both behavioral and pharmacologic treatments for ADHD, and brain-machine interface tools. I also discuss behavioral training protocols that can improve focus in people with ADHD and those without ADHD, and for people of different ages. I discuss the role of dopamine in coordinating 'default-mode' and 'task-related' neural networks, attentional "blinks" (lapses of attention) and how to overcome them, and the role of actual blinks in time perception and attention. Finally, I review some of the prescription and over-the-counter compounds for increasing focus such as Adderall, Ritalin, Modafinil and Armodafinil, the racetams, Alpha-GPC and phosphatidylserine and the role of diet for managing ADHD (and the controversies of diet for ADHD). The role of cell phones/technology in ADHD and ADHD-like challenges with focus are also discussed. Throughout, both basic science and clinical scenarios, as well as applicable tools and resources are covered.

Healthy Eating & Eating Disorders - Anorexia, Bulimia, Binging | Episode 36
8178
In this episode, I discuss what drives hunger and satiety, and the role our brain, stomach, fat and hormones play in regulating hunger and turning off the desire to eat more. I also address how protein is assimilated better early in the day than it is later in the day, and why those using intermittent fasting might want to shift their feeding window to earlier in the day.   Then I delve into the topic of disorders of eating: Anorexia Nervosa, where people starve themselves and Bulimia Nervosa where people binge and purge their food. I discuss some common myths about Anorexia such as the role of media images increasing the rates of anorexia and the myth of the "perfectionist" anorexic. I also review the symptoms, and the brain and chemical systems disrupted in this condition. I explain how anorexics become hyperaware of the fat content of foods and develop reflexive habits of fat-hyperawareness. Then I discuss the most effective treatments ranging from family-based models to those that target the habitual nature of low-fat/calorie food choices. I also discuss new more experimental clinical trials on MDMA, Psilocybin and Ibogaine for Anorexia, and both their promise and risks   I review the latest work on binge eating disorder and brain stimulation, drug treatments and thyroid disruption in Bulimia and why the treatments for Bulimia are so similar to those for ADHD. Finally, I discuss "cheat days," body dysmorphia and the growing list of novel forms of eating disorders start to finish. As always, science and science-based tools are discussed.   Thank you to our sponsors: Belcampo - https://www.belcampo.com/huberman -- code "huberman" Headspace - https://www.headspace.com/specialoffer Athletic Greens - https://www.athleticgreens.com/huberman   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Links: Ingesting Protein in the Morning Supports Muscle Maintenance & Growth: https://bit.ly/3DPlms7  Studies Using Virtual Reality to Explore Eating & Hunger & Body Image: https://bit.ly/3BGaDya  https://bit.ly/2WWGRq8    Timestamps: 00:00:00 Introduction: Fasting, & Defining Healthy Eating 00:08:55 Morning Protein Is Important  00:22:04 Sponsors 00:26:29 Defining & Diagnosing Eating Disorders 00:29:00 Anorexia Nervosa (Overview & Myths) 00:33:44 Bulimia (Overview & Myths) 00:37:35 Binge Eating Disorders, EDNOS, OSFEDS, Pica 00:39:44 What is Hunger?

Dr. Robert Sapolsky: Science of Stress, Testosterone & Free Will | Episode 35
5389
In this episode, I interview Dr. Robert Sapolsky, Ph.D., Professor of Biology, Neurology & Neurosurgery at Stanford University. We discuss stress, what defines short-term versus long-term stress, and how stress can be beneficial or detrimental, depending on the context. We also discuss stress mitigation and how our sense of control over stress mitigation techniques, including exercise, determine health outcomes. Dr. Sapolsky explains some of the key effects of the hormone testosterone — how it can amplify pre-existing tendencies for aggression or sexual behavior, but that it does not produce those behaviors per se. He also explains how testosterone impacts our social hierarchies, sense of confidence, and willingness to embrace challenges of different kinds. He also explains how our behaviors and perceptions shape testosterone levels. And we discuss estrogen and the powerful role it plays in brain development, health and longevity. Finally, we discuss free will, what it means to have free will, and if we have any free will, including how knowledge alone might allow us to make better decisions for ourselves and society.    Thank you to our sponsors: ROKA - https://roka.com - use code "huberman" InsideTracker - https://insidetracker.com/huberman  Belcampo - https://belcampo.com/huberman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Join Newsletter - https://hubermanlab.com/neural-network    Links: Dr. Sapolsky's most recent book, "Behave: The Biology of Humans At Our Best & Worst": https://amzn.to/3yrZ6k7  Support Research in the Huberman Lab at Stanford on Stress, Sleep & Human Performance: https://hubermanlab.stanford.edu/giving    Timestamps: 00:00:00 Introduction: Dr. Robert Sapolsky  00:02:26 Sponsors: Roka, Inside Tracker, Belcampo  00:06:30 Stress: Short & Long-Term, Good & Bad  00:09:11 Valence & Amygdala  00:11:00 Testosterone: Common Myths vs. Actual Truths  00:15:15 Behaviors that Affect Testosterone   00:17:20 Mindsets & Contexts that Affect Testosterone 00:20:28 How Finger Length Ratios Reflect Prenatal Hormone Levels   00:22:30 Aggression: Male-Female, Female-Male, & Female-Female  00:24:05 Testosterone: The Challenge Hypothesis  00:29:20 How Dopamine Impacts Testosterone & Motivation  00:32:32 Estrogen: Improves Brain & Longevity BUT TIMING IS KEY  00:39:40 Are Testosterone & Sperm Counts in Males Really Dropping?  00:42:15 Stress Mitigation & Our Sense of Control  00:51:35 How Best to Buffer Stress  00:57:04 Power of Perception, Choice & Individual Differences  01:00:32 Context-Setting, Prefrontal Cortex & Hierarchy  01:11:20 How Dr. Sapolsky Accomplishes Deep Thinking   01:13:17 Do We Have Free Will?  01:20:50 How to Apply Knowledge & Learning   01:23:44 Robert’s New Book: “Determined: The Science of Life Without Free Will”  01:28:27 Reflections, Support of Podcast, & Supporting Stress Research

Understanding & Conquering Depression | Episode 34
7322
This episode, I explain what major depression is at the biological and psychological level and the various treatments that peer-reviewed studies have revealed can help prevent and treat depression. I explain the three major chemical systems that are altered in depression: norepinephrine, serotonin and dopamine. I discuss genetic predispositions to depression and how stress, thyroid hormone and cortisol play a role in many forms of depression. I also discuss inflammation as a common feature of many depression symptoms. I review 8 specific science-supported protocols for treating and avoiding depression, including EPA fatty acids (which have been shown to rival certain prescription treatments), how exercise protects against depression, studies of creatine, adjusting dopamine balance and more. I also discuss the results of ongoing clinical trials for ketamine and psilocybin for depression, how these compounds work and finally, I review how ketogenic diets can help in certain cases of depression, especially treatment-resistant major depression.   Thank you to our sponsors: InsideTracker - https://www.insidetracker.com/huberman Athletic Greens - https://www.athleticgreens.com/huberman Belcampo - https://www.belcampo.com/huberman -- code "huberman"   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Join Newsletter - https://hubermanlab.com/neural-network   Links: Review of EPAs for the Treatment of Depression - https://bit.ly/2Wl15ti  Review of Creatine for the Treatment of Depression - https://www.mdpi.com/520864  Recent Study on the Clinical Use of Psilocybin for Treatment of Depression - https://bit.ly/3sFSGMM    Timestamps: 00:00:00 Mood Disorders & Maintaining Mental Health (Protocol 1) 00:07:10 Sponsors 00:11:15 Major Depression 00:18:40 “Anti-Self” Confabulation 00:21:42 Autonomic (Vegetative) Symptoms of Depression 00:26:58 Norepinephrine, Dopamine & Serotonin 00:31:50 SSRIs (Prozac, Zoloft, etc.): Selective Serotonin Reuptake Inhibitors 00:37:00 Epinephrine/Motor Functions, Dopamine/Motivation & Craving, Serotonin/Emotions 00:39:33 Physical & Emotional Pain are Linked: Substance P 00:41:50 Hormones & Depression: Thyroid & Cortisol  00:46:50 Genetic Susceptibility to Depression: Impact of Stress  00:50:50 Understanding Biological Mechanism Is Key: Recipes versus Skills 00:52:50 Tools for Dealing with Depression: Logic & Implementation (Protocol 2) 00:56:25 Brain Inflammation & Mental State: Cytokines, Prostaglandins, etc. 00:59:20 Protocol 3: Essential Fatty Acids (Omega-3, EPAs: Eicosapentaenoic Acid)* 01:02:50 How EPAs Help Offset Depression: Serotonin Synthesis, Kynurenine, Quinolinic Acid 01:05:25 Protocol 4: How Exercise Offsets Depression  01:11:44 Protocol 5: Creatine Monohydrate, Forebrain Function & NMDA receptors* 01:20:30 Protocol 6*: Ketamine, PCP (*Prescription-Only), & NMDA-Receptor Function 01:33:08 Protocol 7*: Psychedelics (*In Clinical Trials) for Major Depression: Psilocybin* 01:47:00 Protocol 8: Ketogenic Diet, GABA (Gamma-Aminobutyric Acid) 01:54:50 Summary of Protocols Covered 02:00:10 Support & Additional Resources

Dr. Anna Lembke: Understanding & Treating Addiction | Episode 33
7351
This episode I interview Dr. Anna Lembke, MD, Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic at Stanford University School of Medicine. Dr. Lembke is a psychiatrist expert in treating addictions of all kinds: drugs, alcohol, food, sex, video games, gambling, food, medication, etc. Dr. Lembke is also an expert in the opioid crisis, and the author of Dopamine Nation: Finding Balance in the Age of Indulgence (https://amzn.to/3AHHGBp). We discuss the biology and psychology of why people become addicted to certain substances and behaviors and the key role that our "dopamine balance" plays in creating addiction. We also discuss the science and practice of how to conquer addictions, why people relapse and how to avoid relapsing. Dr. Lembke also shares her expertise on topics closely related to addiction such as community, shame and lying and she explains why telling the truth—even about the most basic things in daily life, adjusts dopamine levels in our brain. This episode is an important one for anyone struggling with addictions of any kind, for their friends and families and for health care professionals. It is also for anyone who has defeated addiction and is determined to stay clean. Last but not least, it helps explain why all humans do what we do, and how we can all maintain a healthy sense of pleasure seeking in life.   Thank you to our sponsors: ROKA - https://www.roka.com -- code: huberman InsideTracker - https://www.insidetracker.com/huberman Headspace - https://www.headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Join the Neural Network - https://hubermanlab.com/neural-network   Dr. Anna Lembke Links: Website: https://bit.ly/3iPtGje   Stanford Profile: https://stanford.io/3AI9SEu  Dopamine Nation (new book): https://amzn.to/3AHHGBp    Timestamps: 00:00:00 Dr. Anna Lembke, Addiction Expert 00:02:25 Disclaimer & Sponsors: Roka, InsideTracker, Headspace 00:07:00 Dopamine, Happiness & Impulsivity  00:15:56 What Is Pleasure?  00:18:20 Addiction, Boredom & Passion for Life 00:24:00 Pain-Pleasure Balance Controls Addiction 00:29:10 Dopamine Deficits, Anhedonia 00:30:47 Are All Addictions the Same? 00:35:38 Boredom & Anxiety Lead to Creativity  00:40:35 Finding Your Passion Starts with Boredom & Action Steps  00:50:05 How to Break an Addiction 00:55:25 Relapse, Craving & Triggers 01:07:40 Can People Get Addicted To “Sobriety”?  01:11:45 Are We All Wired for Addiction?  01:15:57 Bizarre Addiction 01:18:14 Recovered Addicts Are Heroes 01:20:10 Lying, Truth Telling, Guilt & Shame 01:30:40 Clinical Applications of: Ibogaine, Ayahuasca, Psilocybin & MDMA  01:40:20 Social Media Addiction  01:51:25 Narcissism  01:53:30 Goal Seeking, Success & Surprise 01:58:10 Reciprocity 02:01:15 Closing Comments, Resources

How to Control Your Sense of Pain & Pleasure | Episode 32
8171
This episode I discuss our sense of pain and pleasure: where and how they each arise in our mind and body and various ways to control their intensity. I discuss the science of behavioral tools like acupuncture and hypnosis and directed pressure, including the neural circuits they each activate to modulate our experience of pain or pleasure. I also discuss whole body pain, pain "syndromes" and novel pain relief compounds such as Acetyl-L-Carnitine, SAMe and Agmatine. I discuss neuroplasticity of the pain system and the key role that visual perception plays in pain modulation. Finally, I address the link between dopamine, serotonin, and oxytocin, with arousal, pleasure and pain. As always, both basic science and various protocols are described. Note: The description of the dorsal root ganglia (DRGs) was intentionally simplified and does not include mention of dorsal horn spinal relay neurons, etc. For an excellent full text review of this anatomy and circuits for touch sensing, please see: https://bit.ly/3jH9CPf   Thank you to our sponsors: InsideTracker - https://www.insidetracker.com/huberman Helix Sleep - https://www.helixsleep.com/huberman Athletic Greens - https://www.athleticgreens.com/huberman   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Join the Neural Network - https://hubermanlab.com/neural-network   Links: Instagram discussion with Dr. Sean Mackey, MD, PhD - https://www.instagram.com/p/CMVq0X8Bk1D/ Agmatine study - https://bit.ly/3CtTwRn  Mechanistic basis of acupuncture - https://bit.ly/2VHi0pz    Timestamps: 00:00:00 Skin, Pain, Pleasure  00:01:50 Protocol 1: Maximizing Motivation (with Dopamine & Pleasure) 00:07:12 Sponsors: InsideTracker, Helix Sleep, Athletic Greens 00:12:04 Pleasure & Pain, & Skin Sensors  00:18:13 Sensing Touch with Your Brain: Magnification of Feet, Hands, Lips, Face, Genitals 00:22:16 Two-Point Discrimination, Dermatomes 00:28:11 Thoughts & Genes That Make Physical Pain Worse 00:33:45 Expectations, Anxiety, & Pain Threshold 00:40:27 Protocol 2: Cold Sensing Is Relative; Getting Into Cold Water 00:45:22 Protocol 3: Heat Is Absolute 00:48:10 Injury & Pain 00:52:04 Protocol 4: Plasticity of Pain: Key Role of Vision  00:58:08 Sensing Disparate Body Parts As Merged 01:01:00 Pain “Syndromes”, Psychogenic Fever, “Psychosomatics” 01:04:40 Fibromyalgia, Naltrexone, Protocol 5: Acetyl-L-Carnitine  01:12:24 Protocol 6: Agmatine, S-adenosyl-L-methionine (SAMe), L-5-Methyltetrahydrofolate* 01:17:27 Acupuncture: Mechanism, Non-Responders, Itch & Inflammation 01:28:20 Laser Photobiomodulation, Protocol 7: Hypnosis (reveri.com)  01:30:00 Protocol 8: Pressure-Based Pain Relief, “Gate Theory of Pain (Relief)” 01:37:53 Redheads & Pain Thresholds, Endogenous Opioids  01:44:02 Protocol 8: Love & Pain, Dopamine 01:49:23 Pleasure & Reproduction, Dopamine & Serotonin, Oxytocin 01:51:40 Protocol 9: PEA, L-Phenylalanine (Precursor to Tyrosine) 01:55:40 Contextual Control of Pleasure by Autonomic Arousal, Dopamine Baselines 01:59:40 Pleasure-Pain Balance 02:01:24 Protocol 10: Controlling Pleasure, Dopamine & Motivation Over Time 02:06:40 Protocol 11: Immediate, Non-Goal-Directed Pleasure, PAG  02:08:40 Direction of Touch: Pleasure Versus Pain, Arousal & Touch “Sensitivity”  02:13:00 Synthesis & How to Conceptualize Pain and Pleasure, Support

How to Optimize Your Brain-Body Function & Health | Episode 30
6763
This episode I describe how the organs of the body influence the function and health of our brain and how our brain controls our bodily organs. The conscious awareness of this brain-body dialogue is called interoception. I describe how two factors- mechanical forces (e.g., pressure, pain, volume, etc.) and chemical factors (e.g., gut acidity, microbiome diversity, etc.) combine to influence our moods, control inflammation, immune system, recovery from injury and more. I explain how specific actions of our lungs, heart, spleen, and diaphragm, control our brain via the vagus nerve and other neural pathways. I describe 11 science-supported protocols for enhancing brain-body health and the logic behind them.   Thank you to our sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker - https://www.insidetracker.com/huberman Headspace - https://www.headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Join the Neural Network - https://hubermanlab.com/neural-network   Links: Sonnenburg, Cell Press Study - https://bit.ly/SonnenburgCellPress   Timestamps: 00:00:00 Your Sense of Self: Interoception 00:01:25 Protocol 1: Fermented Foods, Not Fiber, to Reduce Inflammation  00:03:30 Attributions 00:08:22 Main Drivers of Feelings & Performance 00:11:45 Brain-Body: A Mechanical & Chemical Dialogue  00:17:50 LDB (Lung-Diaphragm-Brain) Dialogue   00:21:00 Protocols 2, 3, 4: Control Heart Rate With Breathing 00:29:08 Sensing Lung Pressure: Piezo Receptors 00:30:54 Carbon Dioxide, From Air to Blood 00:34:02 Protocol 5: Alert While Calm 00:40:50 Baroreceptors: Hering-Breuer Reflex 00:42:47 Gut Volume & The Desire to Open Your Mouth  00:48:18 Protocol 6: Enhancing Gut-To-Brain Communication, Fasting  00:51:50 Intestines, Fatty Acids, Amino Acids & Sugar 00:57:00 Protocol 7: Reducing Sugar Cravings with Specific Amino Acid Nutrients  00:58:58 Gut Acidity (Is Good) 01:02:20: Improving Nasal Microbiome  01:04:13 Inflammation & Microbiome: Fiber vs. Fermented  01:11:15 Protocol 8: Reducing Inflammation & Enhancing Brain Function w/Fermented Foods 01:13:10 Leaking Guts, Auto-Immune function & Glutamine 01:15:50 Gut Acidity: HCl (hydrochloric acid), Pepsin 01:18:30 Probiotics & Brain Fog 01:21:45 Nausea: Happens in Your Brain; Area Postrema 01:28:25 Protocol 9: Reducing Nausea: Ginger, Peppermint, CBD, etc. 01:30:40 Fever: Triggers and Control Knobs: OVLT 01:37:00 Protocol 10: Cooling the Blood Properly 01:38:53 Sensing Feelings, Vagus Nerve, Stress 01:41:50 Mental Emotions Reflect Bodily Conditions 01:45:00 Sensing Other People’s Emotions via the Body 01:46:00 Protocol 11: Increasing Interoception, Sensing Heartbeat  01:50:40 Conclusions & Resources

The Science of Hearing, Balance & Accelerated Learning | Episode 27
7416
This episode I describe how our ears and nervous system decode sound waves and gravity to allow us to hear and make sense of sounds. I also describe protocols for rapid learning of sound and other types of information. I discuss sound localization, doppler effects (sound motion), pitch perception and how we isolate sounds in noisy environments. I also review the scientific findings on binaural beats and white noise and how they can improve learning. Other topics and protocols include tinnitus, sea sickness, ear movement, ear growth and the science-supported ways we can all accelerate learning using "gap effects".   Thank you to our sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker - https://www.insidetracker.com/huberman Headspace - https://www.headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Neural Network - https://hubermanlab.com/neural-network   Links: Review on spacing effects and learning: https://bit.ly/3qM6bto  Micro-rest and accelerated learning: https://bit.ly/3hitXKM  Ear movement: https://bit.ly/2TrS9Bf  Ears making sounds, hormones: https://bit.ly/3yneKgV  Binaural beats: review and references: https://bit.ly/36fggFO    Timestamps: 00:00:00 Overview of Topics 00:02:20 Protocol: New Data for Rapid Learning  00:09:10 Introduction: Hearing & Balance  00:13:53 How We Perceive Sounds 00:21:56 Your Hearing Brain (Areas)   00:23:48 Localizing Sounds 00:28:00 Ear Movement: What It Means  00:33:00 Your Ears (Likely) Make Sounds: Role of Hormones, Sexual Orientation  00:35:30 Binaural Beats: Do They Work?  00:43:54 White Noise Can Enhance Learning & Dopamine 00:51:00 Headphones 00:55:51 White Noise During Development: Possibly Harmful 01:03:25 Remembering Information, & The Cocktail Party Effect 01:12:55 How to Learn Information You Hear 01:18:10 Doppler 01:22:43 Tinnitus: What Has Been Found To Help? 01:30:40 Aging: How Big Are Your Ears? 01:35:00 Balance: Semi-Circular Canals 01:40:35 A Vestibular Experiment 01:43:15 Improve Your Sense of Balance 01:48:55 Accelerating Balance 01:51:55 Self-Generated Forward Motion 01:56:25 Dizzy versus Light-Headed 01:58:38 Motion Sickness Solution 02:01:23 Synthesis

How Smell, Taste & Pheromone-Like Chemicals Control You | Episode 25
7180
This episode explains how we sense chemicals through smell, taste, and pheromones. How things smell and taste and chemicals in the tears, breath, and on the skin of others have a profound effect on how we feel, what we do, and our hormones. I explain the 3 types of responses to smell, the 5 types of tastes, the possible existence of sixth taste sense, and how the act of sniffing can make us learn and focus better. I explain how smell and taste reflect brain health and can assess and even promote brain regeneration. I discuss how eating specific categories of foods makes us crave more of those foods, including how to make sour things taste sweet and develop a heightened sense of smell and taste.  Sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker Athletic Greens   Timestamps: 00:00:00 Intro 00:06:02 Sensing Chemicals: Smell, Taste and Chemicals That People Make To Control Each Other  00:09:10 Vision Protocols Recap (Brief): Near-Far Viewing and 2 hours/day outside, and Correction  00:12:20 Color Vision: Excellent Resource: What is Color?

The Science of Vision, Eye Health & Seeing Better | Episode 24
6577
This episode I describe how we see, meaning how our eyes focus, convert light information into electricity the rest of the brain can understand and how our brain creates the incredible thing we experience as “sight”. I also describe how we can train and support our visual system to improve at any age. I describe more than a dozen protocols to support depth perception, offset near-sightedness, improve mood, sleep, and our ability to focus (both visual focus and our mental focus generally). I also explain how to use eyesight to improve our levels of alertness and why visual hallucinations, lazy eyes and colorblindness occur. I also describe various compounds that may assist in supporting visual health and possibly improve our vision. Many simple, zero-cost protocols and a lot of scientific mechanisms are covered in this episode in clear language anyone can understand-- it is for anyone that values their brain and whether eyesight, young, adult-age or advanced age.   Thank you to our sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker - https://www.insidetracker.com/huberman Helix Sleep - https://www.helixsleep.com/huberman   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman   Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website: https://hubermanlab.com Join the Neural Network: https://hubermanlab.com/neural-network   Link to eye exercise videos for smooth pursuit, amblyopia, etc. (Numbering of videos does correspond to numbers in episode caption.) https://www.youtube.com/c/VisualExercises/videos   Timestamps: 00:00:00 Introduction 00:04:51 Protocol: Concurrent Training For Endurance, Strength, Hypertrophy 00:07:24 The Senses, Vision, Seeing & What We Should All Do To See Better 00:10:35 Our Eyes: What They Really Do, & How They Work 00:14:30 Converting Light Into Electricity Language: Photoreceptors, Retinal Ganglion Cells 00:17:00 We Don’t See Anything Directly: It Is All A Comparison Of Reflected Light 00:19:35 Dogs, Cats, Snakes, Squirrels, Shrimps, Diving Birds, & You(r View Of The World) 00:24:05 Everything You See Is A Best Guess, Blind Spots 00:25:50 Depth Perception 00:28:00 Subconscious Vision: Light, Mood, Metabolism, Dopamine; Frog’s Skin In Your Eyes 00:32:00 Blue-Yellow Light, Sunlight; & Protocol 1 For Better Biology & Psychology; 00:35:00 Protocol 2: Prevent & Offset Near-Sightedness (Myopia): Outdoors 2 Hours Per Day 00:42:00 Improving Focus: Visual & Mental; Accommodation, Your Pupils & Your Bendy Lens 00:48:50 Protocol 3: Distance Viewing For 20min For Every 90 Minutes of “Close Viewing” 00:52:20 Protocol 4: Self-Generated Optic Flow; Move Yourself Through Space Daily 00:54:26 Protocol 5: Be More Alert; Eyelids, Eye Size, Chin Position, Looking Up Versus Down 00:59:21 Protocol 6: Sleep In A Very Dark Room To Prevent Myopia (Nearsightedness) 01:02:55 Color Vision, Colorblindness, Use Magentas Not Reds, 01:04:32 Protocol 7: Keeping Your Vision Sharp With Distance Viewing Every Day 01:06:05 Protocol 8: Smooth Pursuit 01:08:48 Protocol 9: Near-Far Visual Training 2-3 Minutes 3-4 Times a Week 01:13:33 Protocol 10: Red Light, Emerging Protocol To Improve Photoreceptors & Vision 01:16:20 Dry Eyes; Blinking, Protocol 11 01:18:40 Lazy Eye, Binocular Vision, Amblyopia; Triggering Rapid Brain Plasticity; Protocol 12 01:24:48 Protocol 12: Determine Your Dominant Eye; Near-Far Training 01:27:57 Visual Hallucinations: The Consequence of An Under-Active Visual Brain 01:29:47 Protocol 13: Snellen Chart: A Simple, Cost-Free Way To Test & Maintain Vision 01:33:00 Vitamin A, Lutein, Idebenone, Zeaxanthine, Astaxanthin, Blood Flow 01:44:20 Summary of Protocols, Vital Point About Blood & Oxygen For Vision 01:46:00 Episode Length, Captions, Zero-Cost Support, Instagram, Searching Topics

How To Build Endurance In Your Brain & Body | Episode 23
7530
In this episode, I discuss endurance: our ability to perform effort over extended amounts of time. I describe the four kinds of endurance: Muscular endurance. Long-duration (single-set) efforts. The two kinds of high-intensity interval training that can benefit our brain and various systems of our body. I discuss the fuel systems they each rely on and how to build up your capillary beds in muscle and in the brain to increase oxygen utilization or improve postural endurance. I discuss efficiency of effort, maximizing quality of effort, and the simplest hydration formula. I review how our heart literally gets stronger (as a muscle) when we oxygenate muscles properly and ways to warm up with and improve respiration/breathing. I also discuss motivation for long bouts of work and the visual physiological basis of the "extra gear" we all can leverage for effort. Finally, I review how accelerating as we fatigue can allow us to access untapped energetic resources. As always, both science, mechanism and tools are discussed throughout Thank you to our sponsors: ROKA - https://www.roka.com - code: huberman InsideTracker - https://www.insidetracker.com/huberman Athletic Greens - https://www.athleticgreens.com/huberman   Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: https://www.thorne.com/u/huberman   Mechanistic review of training adaptations Example protocols

Science & Tools For Muscle Growth, Increasing Strength & Muscular Recovery | Episode 22
7460
In this episode I describe how our brain and nervous system control muscle tissue and how to leverage that for muscle maintenance, growth (hypertrophy) and recovery. I explain how neurons control muscle contractions and limb movements. I explain muscle metabolism and muscle fiber recruitment. I detail protocols for increasing muscular growth and for neuro-muscular recovery. I explain the effects of deliberate cold, anti-inflammatory agents, and anti-histamines on training progress. I describe science-supported protocols using certain weight load ranges, total sets per week, training intensity, frequency, and in-between set activities if one's goal is to increase muscle growth, strength or endurance. I review three foundational compounds and nutrients and three optimization compounds and nutrients that have been shown to improve neuro-muscular performance. Finally, I explain how to leverage exercise and weight training to enhance cognitive function.   Thank you to our sponsors: InsideTracker - https://insidetracker.com/huberman Belcampo - https://belcampo.com/huberman Headspace - https://headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman   Supplements from Thorne: http://www.thorne.com/u/huberman

How to Learn Skills Faster | Episode 20
6734
This episode I discuss the science and practice of learning physical skills: what it involves at a biological level, and what to focus on during skill learning at each stage to maximize learning speed and depth. I also describe what to do immediately after a training session (note: this is different than the optimal protocol for cognitive skill training) and as you progress to more advanced levels of performance. I also cover the science of skill-based visualization which does have benefits, but only if done correctly and at the correct times.

Supercharge Exercise Performance & Recovery with Cooling | Episode 19
5030
This episode I explain the science of heating and cooling the body, a process called thermoregulation-- and how to apply that knowledge to significantly improve physical performance. I describe the three areas of our body that can remove heat (or bring heat into the body) faster than anywhere else, why that is so, and how proper cooling of these areas with specific protocols can allow people to perform 200-600% more volume and repetitions of resistance exercises at the same weight loads, or to run, cycle or swim significantly further. I also describe how to use directed cooling of so-called glabrous skin: the bottoms of feet, palms and face, to significantly enhance recovery times from exercise. Also, why the common practices of trying to heat up or cool the body via the torso or whole-body submersion in cold can be inefficient and/or dangerous-- and the better alternatives. Finally, I discuss the temperature-effects of caffeine, alcohol and anti-inflammatory compounds. The information in this episode is focused on mechanisms and tools for increasing athletic or exercise performance.   Thank you to our sponsors: InsideTracker - https://insidetracker.com/huberman Helix - https://helixsleep.com/huberman Theragun - https://theragun.com/huberman   Our Patreon page: https://www.patreon.com/andrewhuberman Supplements from Thorne: http://www.thorne.com/u/huberman Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab   Timestamps: 00:00:00 Introduction 00:05:08 Physical Performance & Skill Learning 00:06:40 Optimal Learning Protocol (Recap): 4 Steps 00:08:31 Variables Impacting Physical Performance 00:10:00 Temperature Is the Dominant Variable 00:12:08 Understanding Mechanism Is Key 00:13:42 Heat: The Enemy of All Performance (& Why) 00:16:30 Blood Flow & Sweating & Piloerection 00:22:35 Heat Is What Limits Effort: Even If You Feel Fine/Motivated 00:25:29 Proper Cooling Can Double, Triple, Quadruple (Or More) Your Ability 00:26:42 Heat Induced Confusion & Death 00:30:02 The Three Body Parts Best For Heating & Cooling Your Whole Body 00:31:38 Face, Palms, Bottoms of Feet; Glabrous Skin 00:33:00 Arterio-Venous Anastamoses (AVAs) Are Super Cool(ing)! 00:37:15 Palmar Cooling Can Supercharge Your Athletic Performance 00:38:35 ATP, Pyruvate Kinase & Heat 00:40:55 Palmer Cooling Outperforms Anabolic Steroids Several-Fold 00:43:45 Increasing Endurance, Willpower & Persistence 00:46:33 Cardiac Drift, & Moving the ”I Quit” Point 00:50:44 Deliberate Heating: Myths and Better Protocols 00:53:20 Protocols For Self-Directed Cooling To Vastly Improve Performance 00:59:23 How To Use Cold To Recover Faster & More Thoroughly 01:02:05 Ice Baths & Cold Showers Can Prevent Training Progress: mTOR, etc. 01:06:29 Alcohol, Caffeine, NSAIDs: Their Temperature Effects Matter 01:09:44 Are Stimulants Counter Productive For Performance?

Boost Your Energy & Immune System with Cortisol & Adrenaline | Episode 18
6397
This episode I describe the biology of two essential hormones we all make: cortisol and adrenaline (also called epinephrine). Cortisol and adrenaline powerfully regulate our levels of energy, focus and immune system function. I describe various science-supported tools and practices to increase or decrease cortisol and/or adrenaline, depending on one's specific needs and goals. I also describe the biology of nootropics, and how cortisol and adrenaline can improve or degrade learning. Finally, I review the scientific data and tools for timing the release of these hormones to improve memory, energy and immune system function.   Thank you to our sponsors: InsideTracker - https://insidetracker.com/huberman Athletic Greens - https://athleticgreens.com/huberman Headspace - https://headspace.com/specialoffer   Our Patreon page: https://www.patreon.com/andrewhuberman Supplements from Thorne: http://www.thorne.com/u/huberman Social: Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Links: Intermittent Fasting & Growth Hormone Mechanism https://pubmed.ncbi.nlm.nih.gov/29233536/ Habitual Coffee Drinking & Changes In Brain Connectivity https://pubmed.ncbi.nlm.nih.gov/33875801/ Timestamps: 00:00:00 Introduction 00:05:41 Energy & Your Immune System, & Learning Faster 00:08:34 Why & How Intermittent Fasting Increases Growth Hormone 00:11:56 Why Your Stomach Growls 00:13:09 Hot Baths & Hormones 00:14:35 Energy, Adrenaline (Epinephrine), & Cortisol 00:15:48 Cortisol & Cholesterol, Competition With Testosterone & Estrogen 00:17:54 Adrenaline (Epinephrine) Is Your (Immune Systems) Best Friend 00:18:48 Cortisol Basics In Two (Actually 1) Minute/s 00:19:48 Adrenaline Basics In Two Minutes 00:21:32 Tool: Time Your Cortisol Peak To Waking Using Specific Light Intensities 00:27:20 Brief Increases In Cortisol & Adrenaline Boost Energy, Focus & Immunity 00:30:04 Ways To Increase Adrenaline, Epinephrine & Cortisol & Why That Is Good 00:35:00 Does Mindset During Stress Matter? 00:36:15 Protocols: Adrenaline Breathing Described 00:39:00 Practices To Increase Energy Without Increasing Stress 00:45:00 Using Stressors to ENHANCE Our Immune System: Science & Tools 00:55:11 Timing Thyroid Release For Energy 00:57:02 Adrenaline/Stress Increase Performance & Memory.

How to Control Your Metabolism by Thyroid & Growth Hormone | Episode 17
6360
This episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.

How Hormones Control Hunger, Eating & Satiety | Episode 16
5983
This episode I discuss how hormones from our gut, liver, pancreas and brain control our appetite-- and the specific tools we can use to adjust those hormones in order to achieve specific goals. I explain the brain areas that control our desire to eat, and our desire to stop eating. I discuss a hormone we all can make that is regulated by UV-rays from sunlight that reduces our appetite. I also explain that when we eat controls our appetite and not the other way around (and how to leverage that fact). I describe how we are basically always eating until we reach a threshold level of fatty acids and amino acids in our gut and the factors that can alter that signaling and make us eat far more than we need. I also explain how insulin, glucose and glucagon work, why cholesterol is so key for ovary, adrenal, liver and testes function and how the ketogenic diet impacts glucose and thyroid levels. As always, I describe many tools: specific supplements, prescription compounds, specific types (and timing) of exercise to regulate hormones, specific timing and types of eating, ways to reduce sugar cravings by triggering release of the hormone CCK, and more. Note: A future episode will cover Thyroid hormone. Also, I mis-spoke when explaining POMC neurons. I said “P-M-O-C” but should have said “POMC”. Apologies. The name I gave for what POMC is, however, was correct: "proopiomelanocortin".

How to Optimize Testosterone & Estrogen | Episode 15
7367
In this episode, I discuss testosterone and estrogen hormones and how they impact the brain, body, and behavior after puberty. I also discuss how various behaviors such as exercise (resistance and endurance training) and sex or observing sex impact these hormones and their levels. I ask: "what specifically is it about such activities that impact testosterone and estrogen?"; the resounding theme is that when our nervous system is activated in particular ways, it drives our endocrine system and vascular system to activate or repress certain hormone networks in predictable ways. I also discuss peer-reviewed studies and protocols addressing (at a mechanistic level) how light, cold and heat, and respiration (breathing) can positively or negatively impact testosterone and estrogen. We discuss specific supplements and compounds that peer-reviewed studies illustrate can adjust testosterone and estrogen levels by changing their binding to other proteins, raising them directly, or changing other hormones released from the brain and pituitary. I discuss optimization in the normal reference ranges for these hormones, and I discuss pheromones, apnea, menstrual cycles, menopause and andropause.

The Science of Sexual Development | Episode 14
5902
In this episode, I discuss how hormones such as testosterone and estrogen and their derivatives impact the early development of the brain and body and their maturation. I review published data on environmental factors shown to powerfully alter hormone pathways in animals and humans and the effects of cannabis, alcohol and cell phones on testes, sperm, ovaries and hormones. I describe the predictable relationship between genes, beard growth and balding patterns, and the importance of estrogen for brain development in people of all chromosomal sexes. Finally, I discuss how the hormones we are exposed to in the womb shape the relative length of our finger digits, the sounds our ears make (yes you read that correctly), and how those correlate with people's self-reports of their sexual preferences. As always, basic information and tools are discussed.   Thank you to our sponsors InsideTracker - https://insidetracker.com/huberman Helix Sleep - https://helixsleep.com/huberman Athletic Greens - https://athleticgreens.com/huberman   Our Patreon page https://www.patreon.com/andrewhuberman   Supplements from Thorne https://www.thorne.com/u/huberman   Social Instagram - https://www.instagram.com/hubermanlab Twitter - https://twitter.com/hubermanlab Facebook - https://www.facebook.com/hubermanlab Website - https://hubermanlab.com Newsletter - https://hubermanlab.com/neural-network   Links Mood Meter NSDR video Cell Phones & Hormones Finger-length ratios and sexual orientation (Nature)  Minireview: Organizational Hypothesis: Instances of the Fingerpost (Endocrinology) LeVay Study in Science Magazine on Sexual Orientation Brain Dimorphism   Timestamps (00:00:00) Introduction (00:06:47) Announcement: Mood Meter App Works Again (00:08:00) Maximizing Learning from the Podcast (00:10:00) New Non-Sleep Deep Rest Protocol, Spanish Subtitles (00:11:35) Sexual Differentiation: Hormones, Neurons & Behavior (00:14:15) Hormones Basics (00:15:26) Sperm Meets Egg, Chromosomal Sex, Gonadal Sex, (00:17:50) Y Chromosome Inhibition of Feminization (00:19:00) Placenta Is An Endocrine (Hormone-Producing) Organ, Adrenal Testosterone (00:19:45) Hormonal Sex, Morphological Sex (00:21:04) Hormones Fast & Slow, Sex Steroids Can Turn On Genes (00:23:06) Masculinization, Feminization, Demasculinization, Defeminization (00:23:42) Primary Sexual Characteristics: DHT Drives Penis Development (00:27:03) Secondary Sexual Characteristics (00:27:43) Penis Sprouting: Guevedoces (00:31:25) Estrogen, NOT Testosterone, Masculinizes The Brain (00:33:15) Breast Development In Males: Aromatase; Puberty, & Steroids in Athletes (00:34:50) Estrogen Powerfully Controls Brain Development In All Individuals (00:35:19) Avoiding Hormonal Disruption In Children & Adults: Specific Oils, Creams, Etc.

The Science of Emotions & Relationships | Episode 13
6061
In this episode, I discuss the biology of emotions and moods in the context of relationships. I focus on the science of how early infant-caregiver attachment, combined with adolescence and puberty shape our adult patterns of attachment. I explain the three universal aspects of emotions, the reality of right-brain versus left-brain personalities, and how the roots of adult attachment are also grounded in specific aspects of puberty.

How To Increase Motivation & Drive | Episode 12
5342
This episode explains the science of motivation and drive. I describe how dopamine-- a chemical we all make in our brain, underlies our desire for and pursuit of our goals, as well as our capacity to move and experience pleasure. I describe how we can leverage specific behaviors, reward schedules and dopamine-prolactin balance to help ensure we can maintain motivation and capacity for pleasure over the long term. I also discuss dopamine in the context of ADHD, craving and addiction, and some absolutely amazing results about specificity of drug effects based purely on belief.

Understanding and Using Dreams to Learn and to Forget | Episode 5
4669
This episode is all about the two major kinds of dreams and the sorts of learning and unlearning they are used for. I discuss REM-associated dreams that control emotional learning and their similarity to various trauma treatments such as ketamine and EMDR.
