How to Control Your Metabolism by Thyroid & Growth Hormone

In this Huberman Lab Essentials episode, my guest is Dr. David Berson, PhD, a professor of neuroscience at Brown University and an expert on the visual system and circadian biology. We explore how the brain processes visual information, from photons entering the eye to conscious perception in the cortex. We discuss color vision, the discovery of melanopsin and intrinsically photosensitive retinal ganglion cells, and how light regulates our circadian clock and melatonin release. We also examine the vestibular system's role in balance and motion detection, the cerebellum's function in motor coordination, and the midbrain's integration of multiple sensory inputs. Finally, we discuss the basal ganglia's role in decision-making and an extraordinary case of neuroplasticity in visual cortex. Read the episode show notes at hubermanlab.com.

My guest is Konstantina Stankovic, MD, PhD, Professor and Chair of Otolaryngology at Stanford School of Medicine. She explains how hearing works and why hearing loss—affecting over 1.5 billion people—impacts people of all ages. We discuss how hearing loss impairs focus and increases the risk of cognitive decline, as well as the role of menopause and other biological milestones in hearing health. We share science-backed protocols to protect your hearing and highlight risks to avoid. And we discuss tinnitus—its causes and treatment options.

In this Huberman Lab Essentials episode, I explore how biological rhythms and neurochemicals impact our perception of time. I describe how the body aligns with daily and seasonal light cycles to regulate hormones that influence energy, mood and motivation throughout the year. I share science-based tools to enhance focus and productivity, including strategies for structuring work intervals and optimizing the timing of exercise and daily light exposure. I also explain how neurotransmitters like dopamine and serotonin influence our perception of time and how factors such as novelty, emotion and routine impact how we experience and recall time.

My guest is DJ Shipley, a retired Tier 1 operator Navy SEAL and now a top public educator on how to build mental and physical health and reach top-level performance in any endeavor. DJ’s life is one marked by extraordinary strivings, wins, setbacks and comebacks that together have shaped his approach to overcoming challenges of all kinds and to daily life. DJ explains a regimen of clear, practical steps and a mental stance that can allow anyone—male, female, young or old—to build extreme resilience of mind and body and to be successful in family and work. We also discuss his experience with new, emerging treatments for addiction, PTSD and depression that many people, not just veterans, are benefiting from. The tools DJ describes to “stack small wins” and to be ultra-intentional about your mindset will be of immense benefit to anyone wishing to achieve the best version of themselves.

In this Huberman Lab Essentials episode, my guest is Dr. David Buss, PhD, a professor of psychology at the University of Texas at Austin and a pioneer in the field of evolutionary psychology. We explore the science behind human mate selection in both short- and long-term relationships. We discuss universal traits valued in long-term partners along with key differences between women and men in what they prioritize when selecting a mate. We also discuss the darker aspects of mating behavior, such as deception, the evolutionary function of jealousy and the motivations behind stalking. Read the episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain how the immune system defends against infection and describe the relationship between the immune and nervous systems. I discuss the immune system's three primary layers of defense, emphasizing how each contributes to protection from infection. I share practical tools to enhance immune function and accelerate recovery from sickness, including specific breathing patterns, sleep positioning and targeted supplementation. I also explore the powerful mind-body connection, showing how mindset and nervous system activation can directly influence the body's ability to heal. Read the episode show notes at hubermanlab.com.
