In this Huberman Lab Essentials episode, I explain the biology of flexibility and discuss the organ systems that shape range of motion and limb flexibility. I also discuss different types of stretching, which methods are most effective, and practical tools for timing stretching relative to exercise. Finally, I provide specific protocols for how intensely and how often to stretch to maximize flexibility, support exercise performance, and offset age-related losses of flexibility.

Andy Stumpf is a retired Navy SEAL, world-record-holding wingsuit BASE jumper, martial artist, and author. We discuss the mental framework and moment-to-moment decision-making process that can allow anyone to build discipline and resilience and better navigate both everyday life and life's most challenging moments. Andy explains several simple-yet-powerful tools gleaned from his time in — and after — his SEAL career that can help you determine where to focus your actions and how to clear your mind of things you can't control or that hold you back mentally. Andy also shares and reflects on lessons learned from some of the deeply personal challenges he faced outside of combat and freefall. Finally, we explore the all-too-frequent tragedy of people — including high performers — taking their own lives, and consider what might be done to prevent more such losses.

In this Huberman Lab Essentials episode, I discuss science-supported tools to improve sleep by supporting a healthy circadian rhythm using key behaviors and environmental cues. I explain specific morning, afternoon and evening behaviors that will increase daytime alertness and support deeper, more consistent sleep at night. I also cover sleep supplements, the effects of caffeine, alcohol and THC on sleep, as well as practical strategies for managing jet lag and shift work. Read the episode show notes at hubermanlab.com.

Dr. Marie-Pierre St-Onge, PhD, is a professor of nutritional medicine at Columbia University School of Medicine and an expert on the bidirectional relationship between nutrition and sleep. We discuss how even moderate sleep loss increases appetite, changes hunger-related hormones, and causes weight gain, even when calories are not increased. We also explain how meal timing and specific foods, like fiber, ginger, saturated fat, and various oils, affect sleep onset, sleep quality, and metabolism. Throughout the conversation, we discuss specific foods and diets that directly support weight loss, better sleep, and long-term cardiometabolic health. Read the show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain the neuroscience of grief, including how the brain maps relationships across three dimensions — space, time, and closeness — and why losing someone requires a remapping of those neural circuits. I describe how grief differs from depression, the role of oxytocin in driving yearning after a loss, and why people move through grief at different rates. I also discuss science-based tools for grieving adaptively, including how to access feelings of attachment while decoupling them from episodic memory. Finally, I explain how foundational biology — particularly sleep and cortisol rhythms — shapes our capacity to navigate the grieving process. Read the episode show notes at hubermanlab.com.

Jeff Cavaliere, MSPT, CSCS, is a physical therapist and certified strength and conditioning specialist and one of the world's leading public educators on resistance training to build muscle size and strength, avoiding and overcoming injuries, and improving your posture and movement patterns (biomechanics). We discuss often-overlooked muscles and exercises that support decades of pain-free training and long-term progress. Jeff explains the best and most efficient ways to strengthen glutes, rotator cuff, neck, and foot muscles and connective tissues, and how to resolve back, hip, and other pain. We also cover the essentials of cardio, fat loss, and nutrition and how to make excellent and ongoing progress despite real-life training constraints. This episode is crucial for men and women as young as their teens, 20s, and 30s, all the way up to their 70s, 80s (and beyond) to be strong, mobile, and pain-free.

In this Huberman Lab Essentials episode, my guest is Dr. Eddie Chang, MD, a neurosurgeon and Chair of the Department of Neurological Surgery at the University of California, San Francisco (UCSF). We discuss the neural circuits underlying speech and language, including how the brain controls the larynx, vocal folds and articulators to shape breath into words. We also explore his pioneering work on speech neural prosthetics — brain-machine interfaces that allow paralyzed patients to communicate by decoding neural activity into speech and avatar-driven facial expressions. Additionally, we examine the neurobiology of stuttering, the role of auditory feedback in fluent speech, and the broader ethical questions surrounding brain augmentation technologies.

Dr. Nick Epley, PhD, is a professor of behavioral science at the University of Chicago and a leading expert on the science of social connection. We discuss how seemingly small daily interactions with strangers (as well as with people we know) can meaningfully improve our mental and physical health. Dr. Epley also explains how to reduce social anxiety using simple and easily accessible science-supported tools. We also discuss the data on assumptions — both the ones we and others make — and why so often those are wrong when it comes to social dynamics. Read the episode show notes at hubermanlab.com.
