This is episode 3 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley, and leading public educator about the role of sleep in health, disease and performance.  We explain how our sleep architecture changes as we age. We also cover how childhood development and aging affect sleep biology and needs. We also discuss whether polyphasic sleep (multiple short sleep periods) is beneficial.  Then, we discuss naps, including their positive benefits, individual variability, those who should not nap, and alternative rest states like non-sleep deep rest. Dr. Walker shares protocols to optimize nap duration, timing and effectiveness. We also explore the effects of caffeine on sleep and other health aspects, as well as the optimal timing for caffeine intake. This episode describes many actionable science-based tools for optimizing sleep, naps and caffeine use for better health and performance. The next episode in this special series explores the relationship between sleep, memory, and creativity.

In this episode, my guest is Dr. David Yeager, Ph.D., professor of psychology at the University of Texas, Austin, and the author of the forthcoming book "10 to 25." We discuss how people of any age can use growth mindset and stress-is-enhancing mindsets to improve motivation and performance. We explain the best mindset for mentors and being mentored and how great leaders motivate others with high standards and support. We also discuss why a sense of purpose is essential to goal pursuit and achievement. Whether you are a parent, teacher, boss, coach, student or someone wanting to improve a skill or overcome a particular challenge, this episode provides an essential framework for adopting performance-enhancing mindsets leading to success.

This is episode 2 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology and founder of the Center for Human Sleep Science at the University of California, Berkeley. We discuss basic and advanced tools for improving sleep and explain how sleep quality is affected by temperature, light and dark, caffeine, alcohol, cannabis, nutrition, meal timing, and different medications.  Dr. Walker also provides strategies for coping with a poor night of sleep, wind-down routines, technology in the bedroom, insomnia, visualizations, and building sleep “confidence.”  We also discuss the current status of sleep research for developing advanced techniques to optimize sleep.  This episode provides numerous zero-cost behavioral protocols for improving sleep quality and restorative power, which can benefit daytime mood, energy, performance, and overall health.  The next episode in this special series explores napping, caffeine, and additional protocols to improve sleep.

In this episode 1 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., professor of neuroscience and psychology and founder of the Center for Human Sleep Science at the University of California, Berkeley, and the author of the book “Why We Sleep” discusses the essential role that sleep plays in our health. We cover how sleep affects our hormones, immune system, learning and memory, mood, appetite, and weight regulation. We also discuss what causes the urge to sleep, how sleep is structured throughout the night, and the biology of the different phases of sleep. We also teach you how to determine your individualized sleep needs, including your chronotype (best waking and to-bed time), tips for combat snoring and insomnia, and your QQRT (Quality, Quantity, Regularity, and Timing)—a key framework for optimizing your sleep and therefore daytime energy and focus, and overall health. The next episode in this special series explores how to improve one’s sleep. For show notes, including referenced articles and additional resources, please visit hubermanlab.com.

In this episode, I explain the major categories and types of peptides currently in use for therapeutic purposes. I discuss peptides for improving tissue rejuvenation and repair, promoting longevity, improving muscle growth and fat loss, and boosting mood, vitality, and libido. I explain the biology of how these peptides work and both their potential benefits and risks. I also discuss peptide sourcing, dosages, cycling, routes of administration, and how peptides work in combination.  This episode will help you better understand the rapidly expanding landscape of peptide therapeutics and how to evaluate if specific peptides might be advantageous towards achieving your physical or mental health goals.

In this episode, my guest is Asi Wind. He's one of the world’s top magicians and mentalists.  We discuss what magic and mentalism reveal about the human mind, including how memories are made, how to erase them, and how and why we perceive things the way we do, all in the context of how he performs his astonishing tricks.  Asi explains that magic works because it involves storytelling, which is key to how we organize memories. He also explains how emotional connection allows people to co-create and believe a common narrative, even one that did not actually occur.  We also discuss how Asi's love of painting and photography and his specific daily routine allow him to access creativity. We also discuss fear, perfectionism, and how feeling emotions deeply serves his craft.  Whether you are interested in magic or not, this conversation with Asi will give you an incredible window into how you perceive, learn, and remember the world around you and how what you believe may or may not be based in reality.  For show notes, including referenced articles and additional resources, please visit hubermanlab.com.

In this episode, my guest is Dr. E.J. Chichilnisky, Ph.D., a professor of neurosurgery and ophthalmology at Stanford University. He studies how we see and uses that information to build artificial eyes that restore vision to the blind.  We discuss how understanding the retina (the light-sensing brain tissue that lines the back of our eyes) is critical to knowing how our brain works more generally.  We discuss brain augmentation with biologically informed prostheses, robotics, and AI and what this means for medicine and humanity.  We also discuss E.J.’s unique journey into neuroscience and how changing fields multiple times, combined with some wandering, taught him how to guide his decision-making in all realms of life.  This episode ought to be of interest to anyone interested in learning how the brain works from a world-class neuroscientist, those interested in the future of brain therapeutics and people seeking inspiration and tools for navigating their own professional and life journey.
