This episode I am joined by Dr. Craig Heller, Ph.D., 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.

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.  Read the full show notes for this episode at hubermanlab.com.

This episode I discuss medical research on psychedelic compounds with Dr. Matthew Johnson, Ph.D., 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. He has unprecedented insight into how they can be woven into other psychiatric treatments, changing ones sense of self and of reality. Read the full show notes for this episode at hubermanlab.com.

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. Read the full show notes for this episode at hubermanlab.com.

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.

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.  Read the full show notes for this episode at hubermanlab.com.

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.

This episode I interview Dr. Anna Lembke, M.D., 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. 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.

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.

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. Read the full show notes for this episode at hubermanlab.com.

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".

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.  Read the full show notes for this episode at hubermanlab.com.

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.

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, and the two kinds of high intensity interval training (HIIT). I discuss efficiency of effort and maximizing quality of effort, and a hydration formula. I review how our heart literally gets stronger when we oxygenate muscles properly. 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.

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. Read the full show notes for this episode at hubermanlab.com.

This episode I describe the science of fat loss, including how fat is mobilized and oxidized (burned) and how to increase fat burning by leveraging the nervous system. Most people don't realize it, but our neurons connect to our fat and release epinephrine/adrenaline to facilitate fat oxidation. Read the full show notes for this episode at hubermanlab.com.
