Huberman Lab

My guest is Alex Honnold, a professional rock climber considered by many to be one of the greatest athletes of all time for his historic free solo (no ropes or man-made holds) ascent of El Capitan in Yosemite. We discuss how to envision massive goals in any part of life and the process of breaking down those goals into actionable daily steps. Alex shares how embracing your uniqueness and mortality is the most powerful way to envision and live a fuller, more intentional life. We also discuss strength and endurance training, assessing risk and how Alex prepares mentally and physically for extreme challenges. We also discuss how to balance goal-seeking with family and work. Regardless of your goals, profession or age, this conversation will very likely reshape how you think about and approach your life, goals and potential.

In this Huberman Lab Essentials episode, I explore intermittent fasting and time-restricted eating, highlighting the positive benefits for weight loss, metabolism, organ health, circadian rhythms and cellular repair.

I explain a practical framework for designing a time-restricted eating window that aligns with your lifestyle, exercise schedule and social schedule. I also cover what breaks a fast, how to support fasting with tools like salt intake and post-meal walks, and the use of fasting-related supplements, including berberine and metformin.

My guest is Dr. David DeSteno, PhD, a professor of psychology at Northeastern University. We discuss science, God and religion, including what science can and can’t reveal about the existence of God and where religious faith and science do and do not align. We also discuss why questions about life’s origins, miracles and the afterlife have persisted across time. Dr. DeSteno explains how religious rituals cause meaningful improvements in mental and physical health and how prayer and gratitude can markedly reduce stress, increase honesty and compassion and buffer against loneliness and despair. Finally, we explore what distinguishes religions and mission-based communities from cults, and we discuss the role that communities such as 12-step and Burning Man play in modern life.

In this Huberman Lab Essentials episode, my guest is Dr. Samer Hattar, PhD, the Chief of the Section on Light and Circadian Rhythms at the National Institute of Mental Health.

We discuss how light powerfully shapes mood, sleep, appetite, learning and overall mental health by aligning—or misaligning—our internal circadian clock. We explain practical protocols to support your circadian rhythm, including morning sunlight exposure, dim evening lighting and regular mealtimes. We also discuss strategies to manage jet lag, limit evening screen use, ease seasonal depression and improve focus by syncing light, sleep and food with natural biological rhythms.

My guest is Dr. Sergiu Pașca, MD, professor of psychiatry and behavioral sciences at Stanford University. We discuss the biology and genetics of autism, why autism diagnoses are increasing and recent progress in using stem cells to understand and treat profound autism and other brain disorders. Dr. Pașca explains “organoids and assembloids”—human stem cell–derived tools he pioneered to study, treat and cure complex brain diseases. We also discuss ethical and safety issues with using gene editing and stem cells in humans.

In this Huberman Lab Essentials episode, I explain how dopamine regulates motivation and provide science-based tools to help improve focus, discipline and overall drive.

I explore how particular activities affect dopamine levels and discuss how the highs, lows and baseline levels of dopamine shape your motivation and long-term satisfaction. I also explain practical strategies to boost dopamine levels, such as deliberate cold exposure, caffeine, effort-based rewards and specific supplements. Whether you're looking to enhance motivation for school, work or daily life, this episode explains how to get and stay motivated while supporting healthy dopamine levels.

In this episode, my guest is Dr. Michael Kilgard, PhD, a professor of neuroscience at the University of Texas at Dallas and a leading expert on neuroplasticity and learning across the lifespan. We discuss the need for alertness, effortful focus, post-learning reflection and sleep to induce neuroplasticity, and how dopamine, acetylcholine, serotonin and norepinephrine are each involved. He explains the behavioral steps for neuroplasticity, as well as vagal nerve stimulation (VNS) and other therapies for tinnitus, stroke, depression, PTSD and paralysis. This episode ought to be of use to anyone interested in understanding the modern science of brain rewiring and learning to improve cognitive or motor skills or treat sensory or motor disorders.

In this Huberman Lab Essentials episode, my guest is Dr. Craig Heller, PhD, a professor of biology at Stanford University and a world expert on the science of temperature regulation.

We discuss how the body and brain regulate temperature in different conditions and why conventional cooling methods, such as placing ice packs on the neck, do not effectively reduce core body temperature. Dr. Heller explains why cooling glabrous skin areas—the palms, soles and upper face—efficiently releases body heat and can significantly enhance physical performance and endurance. We discuss how targeted palmar cooling improves both short-term performance and long-term training adaptation in aerobic and anaerobic exercise.

In this episode, I explain cortisol and science-based protocols for properly setting your cortisol rhythm, which can significantly increase your daytime energy, focus, mood, and stress resilience, while also improving your sleep quality.

Most people mistakenly think cortisol is bad, and many assume their levels are too high, when in fact many health and performance challenges simply stem from a disrupted cortisol rhythm. Getting your cortisol rhythm right can be transformative for your health and performance.

I outline behavioral, nutritional, and supplement-based strategies to raise or lower your cortisol levels at the appropriate times of day and night. I also provide specific protocols for overcoming burnout.

If you’re dealing with stress, low energy, hormone or sleep challenges—or simply want to optimize these for the sake of your physical and mental health and performance—this episode offers science-backed protocols to help.

In this Huberman Lab Essentials episode, I explore the biology and psychology of attention-deficit/hyperactivity disorder (ADHD), and discuss both prescription and non-prescription treatment options.

I discuss the neural circuits involved in attention and concentration, emphasizing dopamine's role in regulating and coordinating focus. I explain how common prescription stimulants like Ritalin, Adderall, and Modafinil act on the brain to treat ADHD, and discuss non-drug approaches, including supplements and behavioral training to support focus. The episode offers tools and insights beneficial not only for those with ADHD but for anyone seeking to improve attention and focus.
