How Nature & Other Physical Environments Impact Your Focus, Cognition & Health | Dr. Marc Berman

This episode my guest is Dr. Jack Feldman, Distinguished Professor of Neurobiology at the University of California, Los Angeles and a pioneering world expert in the science of respiration (breathing). We discuss how and why humans breathe the way we do, the function of the diaphragm and how it serves to increase oxygenation of the brain and body. We discuss how breathing influences mental state, fear, memory, reaction time, and more. And we discuss specific breathing protocols such as box-breathing, cyclic hyperventilation (similar to Wim Hof breathing), nasal versus mouth breathing, unilateral breathing, and how these each affect the brain and body. We discuss physiological sighs, peptides expressed by specific neurons controlling breathing, and magnesium compounds that can improve cognitive ability and how they work. This conversation serves as a sort of "Master Class" on the science of breathing and breathing-related tools for health and performance.  For the full show notes, visit hubermanlab.com.

In this episode, I review the science of habit formation and habit elimination and how the process of neuroplasticity (brain rewiring) underlies these processes. I describe two new systems for habit formation. The first system is grounded in the neuroscience of brain states and our ability to perform (and to avoid) certain tasks at different phases of the 24-hour day. The second system focuses on 21-day habit formation and consolidation. I also discuss "task bracketing" as an approach to enhancing habit formation and eliminating unwanted habits and the neural circuits that underlie task bracketing in the basal ganglia (a brain region for generating and stopping behaviors). I also review the science of dopamine rewards and how to apply that knowledge to shaping habits. The science and tools in this episode ought to be helpful for anyone looking to build better habits and eliminate unwanted habits for school, work, fitness, relationships, creative endeavors, and more—indeed for any person or situation where behavioral changes are needed.

In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don't Have To, and the host of the Lifespan Podcast, which launches January 5, 2022.  In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology. This episode includes lots of basic science and specific, actionable protocols, right down to the details of what to do and when. By the end, you will have in-depth knowledge of the biology of aging and how to offset it. Read the full show notes for this episode at hubermanlab.com.

This episode I discuss the science of social bonding- the process by which we form attachments. I explain the neural and hormonal basis for "social homeostasis" (our drive for a given amount of socializing) which reveals why we get lonely, why we seek out connection with others and how power dynamics (hierarchies) shape those connections. I also discuss the neurochemical basis of introversion and extroversion, of trust and how shared experiences that promote similar physiological states in two or more individuals, leads to more rapid bonding. I also discuss how food and oxytocin play key roles in social bonding. This episode covers quality peer-reviewed science and practical tools for anyone seeking to find, build or end relationships.

In this episode, my guest is Dr. David Berson, Ph.D., Professor & Chairman of Neuroscience at Brown University. Dr. Berson discovered the neurons in your eye that set your biological rhythms for sleep, wakefulness, mood and appetite. He is also a world-renowned teacher of basic and advanced neuroscience, having taught thousands of university lectures on this topic. Many of his students have become world-leading neuroscientists and teachers themselves.  Here Dr. Berson takes us on a structured journey into and around the nervous system, explaining: how we perceive the world and our internal landscape, how we balance, see, and remember. Also, how we learn and perform reflexive and deliberate actions, how we visualize and imagine in our mind, and how the various circuits of the brain coordinate all these incredible feats.  We discuss practical and real-life examples of neural circuit function across the lifespan. Dr. Berson gives us a masterclass in the nervous system—one that, in just less than two hours, will teach you an entire course's worth about the brain and how yours works.

In this episode, I discuss fear and trauma, including the neural circuits involved in the "threat reflex" and how specific experiences and memories come to activate that system. I also discuss how our body is involved in trauma and fear. First, I describe the logic of fear mechanisms and how "top-down" processing-- meaning connections from the parts of the brain that assign meaning to our feelings, are involved in fear and erasing fears and traumas. Then I discuss what successful fear and trauma treatment must include and consider various treatments for whether they meet that standard, such as EMDR, Cognitive Behavioral Therapy, Ketamine, other drug-assisted therapies, and more. I also review new data on how 5 minutes per day of deliberate, self-imposed stress can erase fear and depression. And I review the role that social connection plays in erasing or maintaining fears by activating specific molecular pathways in the brain and body. Finally, I review supplementation with over-the-counter compounds for their effects on anxiety and fear and when to take them, if at all.  Read the full show notes for this episode at hubermanlab.com.

In this episode, my guest is Dr. David Buss, Ph.D., Professor of Psychology at the University of Texas, Austin, and one of the founding members of the field of evolutionary psychology. Dr. Buss describes his work on how people select mates for short and long-term relationships, the dynamics of human courtship, and mate value assessment — meaning how people measure up as potential partners. We also discuss the causes of infidelity and differences for infidelity in men and women. He explains how people evaluate and try to alter other people’s mate value as a means to secure and even poach mates. We discuss monogamous and non-monogamous relationships in humans. And we discuss what Dr. Buss calls “the dark triad” — features common in stalkers and narcissists that relate to sexual and psychological violence in relationships. This episode is sure to be of interest to anyone single or in a relationship who seeks to know how people select mates and anyone who is interested in forming and maintaining healthy romantic partnerships.  Read the full show notes for this episode at hubermanlab.com.

In this episode, I discuss the science of gratitude, which has been shown in peer-reviewed studies to have tremendous positive effects on mental and physical health. I explain, however, that most commonly used gratitude practices are ineffective (such as gratitude lists). The key elements of highly effective gratitude practices are described, including the essential need for story (narrative), receiving or perceiving gratitude rather than giving it, and the role that theory of mind plays in this context. I also discuss why we can't simply make up feelings of gratitude and how reluctance undermines the process. I also explain the neural circuit mechanisms that underlie the reductions in fear and increases in motivation and lowering of inflammatory chemicals that effective narrative-based gratitude can trigger. Throughout the episode, I use the science of gratitude to design a brief but highly effective protocol.  Read the full show notes for this episode at hubermanlab.com.
