Dr. Martin Picard, PhD, is a professor of behavioral medicine at Columbia University and an expert on how our behaviors and psychology shape cellular energy production and rates of aging. He explains that your mitochondria don’t just “make energy”; they translate what you do—your mindset and your relationships—into the energy you experience as vitality or lack thereof. He explains how exercise, nutrition, sleep, meditation, and even certain thought patterns and our sense of purpose can charge our cells like batteries. He also shares findings that hair greying is the result of cellular stress and is reversible. This episode links physical and mental ‘energy’ with cellular energy and provides science-supported tools to improve your physical and mental health. Read the episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain how to create lasting habits and break unwanted ones. I explain two habit-building systems: one aligned with daily rhythms and another based on a 21-day cycle of forming and reinforcing habits. I also discuss why habit formation differs between individuals and how certain "linchpin" habits can make other behaviors easier to adopt. Finally, I share practical tools—including visualization, task bracketing, and methods for rewiring bad habits—to support lasting behavioral change. Read the episode show notes at hubermanlab.com.

Dr. Glen Jeffery, PhD, is a professor of neuroscience at University College London and a leading expert on how different colors (wavelengths) of light impact cellular, organ and overall health. He explains that long-wavelength light (red, near-infrared and infrared) can enter the body and brain to enhance mitochondrial function and thereby improve metabolism, eyesight, blood glucose regulation, mood, hormones and more. We also discuss how short-wavelength light from LED bulbs can impair mitochondrial health and why balanced, full-spectrum light is essential for health. Dr. Jeffery shares simple yet powerful ways to use natural and artificial light sources to enhance your metabolic function, eyesight and longevity.

In this Huberman Lab Essentials episode, I discuss the science of social connection and how we form meaningful bonds with others. I explore the neural basis for "social homeostasis"—our drive for a certain amount of social interaction—which explains why we feel lonely, seek connection and how we navigate social hierarchies. I also explain how the brain and neurochemicals, such as oxytocin and dopamine, shape our relationships from infancy through adulthood and underlie traits like introversion and extroversion. The episode also offers practical insights into forming deeper connections and how shared experiences with others enhance social bonding. Read the episode show notes at hubermanlab.com.

My guest is Dr. Jennifer Groh, PhD, professor of psychology and neuroscience at Duke University. She explains how our brain encodes sights and sounds and integrates them so we can navigate and understand the world around us. She explains what thoughts really are and how what you focus on determines your thoughts, not just in that moment but your future thoughts too.

In this Huberman Lab Essentials episode, I explore the neuroscience of fear and trauma and how to effectively process and eliminate traumatic responses. I explain why successful fear treatment requires both extinction of the old fearful response and replacement with a new positive association—not just cognitive reframing. I also explain how the threat reflex activates specific circuits connecting the amygdala, prefrontal cortex, and dopamine systems, and why detailed recounting of traumatic events progressively reduces their physiological impact. Finally, I review evidence-based approaches, including prolonged exposure therapy and cognitive behavioral therapy, discuss how five minutes per day of deliberate stress through cyclic hyperventilation can rewire fear responses, explain the critical role of social connection in activating neural pathways that reduce trauma, and share supplementation options for managing anxiety.

My guest is Dr. David Fajgenbaum, MD, professor of translational medicine and human genetics at the University of Pennsylvania. He explains how, unbeknownst to most doctors, many approved medications can successfully treat or even cure diseases other than the ones they are typically used to treat. He shares his story of escaping death from Castleman's disease by discovering a life-saving treatment using repurposed drugs that were approved for other purposes. Our conversation explores how researchers, physicians, and you—the general public—can explore novel treatments and cures to conditions the medical profession has deemed untreatable, including cancers. We also discuss the crucial role of mindset in battling diseases and the lesser-known use of compounds to promote health and longevity. Read the episode show notes at hubermanlab.com.

Here I explain the lymphatic system, a crucial bodily network for overall health and appearance. I explain how the lymphatic system works to remove cellular waste and fluid from your organs and combat infections. I provide science-based tools that support your lymphatic system for the sake of health and appearance, including: how to reduce fluid retention in your limbs, trunk or face, how to eliminate 'bags' under your eyes and brain fog, and how to improve cardiac health and longevity. Because your lymphatic system lacks a central pump, it needs the mechanical forces generated by specific types of bodily movement, breathing and pressure to circulate your lymph properly, and I explain how you can activate these. I also explain how to support optimal functioning of your glymphatic system, a brain- and spinal cord waste-clearing system active during sleep that is crucial for brain functioning and longevity, including to prevent dementia.

In this Huberman Lab Essentials episode, I explore the science of gratitude and how to develop an effective, research-supported gratitude practice. I explain why common gratitude practices (like simply listing things you're grateful for) are far less impactful than engaging in story-based gratitude practices. I also explain how being grateful activates specific brain regions, which enhance calm, social connection and motivation, while reducing anxiety and inflammation. Finally, I share why we can't simply trick our brains into feeling grateful and describe a practical weekly gratitude practice that will improve both your mental and physical well-being.

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.
