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

My guest this episode is Dr. Justin Sonnenburg, Professor of Microbiology & Immunology at Stanford University. Dr. Sonnenburg’s research focuses on how microbes in our gut impact our mental and physical health and how diet and your environment shape your gut microbiome. We discuss the architecture of the gut microbiome and microbiota variability in different regions of the gastrointestinal (GI) tract and how these can change in response to diet, environment or genetics. We explore the early establishment of your microbiome and how your mode of delivery into the world (C-section or not) shapes your gut. We also discuss lifestyle factors that can alter your microbiome and the integral role the gut microbiome plays in communicating to other organs, including your brain. Dr. Sonnenburg details his recent clinical study, which found that diets rich in fermented foods (but not fiber) increase microbiota diversity and reduce signals of inflammation. Additionally, we examine how foods typical in Western Diets (e.g., high fat, low fiber, processed foods) can negatively impact the gut microbiome. Throughout the episode, we discuss actionable tools from peer-reviewed clinical findings that anyone can implement, regardless of budget, in order to optimize their gut microbiome and health.

In this episode, I discuss the profound effect the gut has on the nervous system. I cover the structure and function of the gut-brain axis and the role of the gut microbiome in the brain and overall health. I describe how the gut controls hunger or satiety by affecting neurons in our brain. I also contrast the many pathways by which the gut influences the brain: direct vs. indirect pathways, chemical vs. mechanical, and fast vs. slow signaling. Additionally, I discuss what defines a healthy microbiome and how your lifestyle impacts the gut microbiome, including the effects of stress, fasting, antibiotics, pets, environment, prebiotics and probiotics. I address how different foods shape the gut microbiome, in particular, the emerging data that fermented foods can increase the diversity of healthy gut microbiota. Throughout the episode, I explain peer-reviewed and textbook findings that reveal the critical role of the gut microbiome in supporting mental and physical health and I outline simple tools that anyone can use in order to enhance their gut microbiome health.

My guest is Dr. David Spiegel MD, Associate Chair of Psychiatry & Behavioral Sciences, Director of the Center on Stress and Health and Director of the Center for Integrative Medicine at Stanford University School of Medicine. Dr. Spiegel has more than 40 years of clinical and research experience with hypnosis, stress physiology, and psychotherapy. In this episode, we examine the role of clinical hypnosis for the treatment of trauma, chronic pain, anxiety and more. Dr. Spiegel explains how to determine your level of ‘hypnotizability’ and provides case studies of incredible successes with hypnosis to treat a variety of ailments. We also discuss how breathing, vision and directed mental focus can modulate internal states and enhance performance. Additionally, we discuss how the adoption of self-hypnosis techniques can reduce stress and enhance sleep in anyone. Dr. Spiegel teaches us how hypnosis works at the neural circuit level to enhance cognitive flexibility. Throughout the episode, Dr. Spiegel summarizes key clinical trials and peer-reviewed findings and resources to work with a trained clinical professional or to do guided self-hypnosis.  For the full show notes, visit hubermanlab.com.

In this episode, I discuss the psychology and biology of desire, love and attachment. I explain how childhood attachment types are thought to inform adult attachment styles to romantic partners, and I describe some of the major theories of human mate selection, relationships and infidelity. Additionally, I explore the neurobiology and proposed subconscious processing underlying desire, love and attachment, including the roles of empathy and “positive delusion." I outline how self-awareness can shift one’s relationship attachment style towards securely bonded partnerships. Finally, I describe specific tools and supplements that have been researched to increase libido and sex drive. Throughout the episode, I explain the science and key mechanisms underlying romantic love and outline tools for those seeking to find a strong, healthy relationship, or for those wanting to strengthen an existing relationship.  For the full show notes, visit hubermanlab.com.

In this episode, I discuss the transformative nature of play—how it changes our feelings, thoughts and actions and indeed, how it can rewire our brain to function better in all contexts. I explain the role of play in childhood, as well as adulthood in skill and social development and describe key characteristics of the mind and body during play. Additionally, I explore how play allows the brain to test contingencies in different roles/environments. Throughout, I discuss the underlying neurobiology of play. I also describe how low-stakes play, and tinkering can broaden and shape your future capabilities. Finally, I discuss how our childhood ‘personal play identity’ informs our adult personality. Throughout the episode, I use the science of play to outline recommendations for using play as a means to enhance neuroplasticity and explore novel situations, regardless of age.

In this episode, I discuss ways to set up your workspace to optimize productivity, focus and creativity. I discuss how to adjust light, physically arrange your work environment, and leverage body posture to enhance productivity. Additionally, I explore how to shift your work environment for particular types of tasks. Moreover, I review the role of body movement in the workspace. I also discuss sound-based tools that can either enhance or diminish cognitive functioning (the ability to focus on deep work). I describe a particular frequency of binaural beats that studies show can be used to enhance memory and recall. This episode covers quality peer-reviewed findings practical tools anyone can use, regardless of budget, in order to optimize their workspace to achieve heightened levels of productivity, increased alertness and focus, and creativity.

My guest is Dr. Alia Crum, Associate (tenured) Professor of Psychology at Stanford University and Director of the Stanford Mind & Body Lab. Dr. Crum is a world expert on mindsets and beliefs and how they shape our responses to stress, exercise, and even to the foods we eat. We discuss how our mindset about the nutritional content of food changes whether it is satisfying to us at a physiological (hormonal and metabolic) level. She also tells how mindsets about exercise can dramatically alter the effects of exercise on weight loss, blood pressure, and other health metrics. Dr. Crum teaches us how to think about stress in ways that allow stress to grow us and bring out our best rather than diminish our health and performance. Throughout the episode, Dr. Crum provides descriptions of high-quality peer-reviewed scientific findings that we can all leverage toward better health and performance in our lives.

In this episode, I discuss the science of setting, assessing, and pursuing goals. I explain the neural (brain) circuits that underlie goal setting and pursuit. Then I describe nine science-supported tools anyone can apply toward their goals. I explain when and how to use goal visualization, when to use multitasking and how to use specific rewards to improve the likelihood of reaching your goals. I also explain why envisioning failures and their consequences are effective and how to set goals of the appropriate level of challenge. I also explain how the molecule dopamine is used to gauge our progress toward milestones and long-term overarching goals and how to leverage dopamine for goal pursuit. Finally, I explain a unique tool called 'space-time bridging' that can be used to support all aspects of goal setting, assessment, and pursuit. This episode ought to be useful for anyone seeking to improve their performance in work, school, exercise, athletics, or personal development. For the full show notes, visit hubermanlab.com.
