My guest is Dr. Christof Koch, PhD, a pioneering researcher on the topic of consciousness, an investigator at the Allen Institute for Brain Science and the chief scientist at the Tiny Blue Dot Foundation. We discuss the neuroscience of consciousness—how it arises in our brain, how it shapes our identity and how we can modify and expand it. Dr. Koch explains how we all experience life through a unique “perception box,” which holds our beliefs, our memories and thus our biases about reality. We discuss how human consciousness is changed by meditation, non-sleep deep rest, psychedelics, dreams and virtual reality. We also discuss neuroplasticity (rewiring the brain), flow states and the ever-changing but also persistent aspect of the “collective consciousness” of humanity.

In this Huberman Lab Essentials episode, my guest is Dr. Alia Crum, PhD, professor of psychology at Stanford University and the director of the Stanford Mind & Body Lab. Dr. Crum explains that our mindsets—for example, what we believe about stress, exercise and the food we eat—shape how we feel, behave and even how our bodies respond. We discuss studies showing simply believing a food is indulgent can shift satiety hormones and that viewing your daily activity as real exercise can improve weight loss and health markers. We also discuss how to reframe stress so it becomes a tool for growth and improved performance. Read the episode show notes at hubermanlab.com.

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. 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. Read the episode show notes at hubermanlab.com.

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.

My guest is Dr. Nirao Shah, MD, PhD, a professor of psychiatry, behavioral sciences and neurobiology at Stanford University School of Medicine. We discuss how the brains of males and females differ and how those differences arise from different genes and hormones during fetal development, in childhood and adulthood. We discuss what drives male- versus female-specific behaviors and how hormonal fluctuations across the lifespan, including puberty, the menstrual cycle, menopause and aging – affect behavior, cognition and health. Additionally, we discuss how biology relates to gender identity and the impact of hormone therapies on brain circuits that regulate mating, parenting and social bonding.
