Essentials: The Science & Process of Healing from Grief

In this Huberman Lab Essentials [https://www.hubermanlab.com/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.

Build Muscle, Great Posture & Resilience to Injury | Jeff Cavaliere

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.

Essentials: The Science of Learning & Speaking Languages | Dr. Eddie Chang

In this Huberman Lab Essentials [/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.

How to Overcome Social Anxiety | Dr. Nick Epley

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.

Essentials: Understanding & Controlling Aggression

In this Huberman Lab Essentials [https://www.hubermanlab.com/essentials] episode, I explain the neural circuits that activate and control aggressive states and behaviors. I discuss how hormones, genes and environmental factors such as day length can shift our aggressive tendencies. I also share science-based tools for modulating aggression, including sunlight exposure, heat therapy and supplementation with ashwagandha or acetyl-L-carnitine.
