The Science & Health Benefits of Deliberate Heat Exposure | Episode 69
I describe the mechanisms by which deliberate heat exposure impacts body temperature, metabolism, heart health, hormone production, exercise recovery, cognition, mood, and longevity. I detail specific protocols for deliberate heat exposure, including exposure times, temperature ranges to consider, time of day, and delivery mechanisms (sauna vs. hot bath vs. open air heat, etc.) in order to achieve different specific outcomes, including dramatic growth hormone releases, or reduction in cortisol levels. I also discuss the ability of locally applied heat to heal or otherwise improve various bodily tissues and new data on how local application of heat may induce the conversion of metabolically sluggish white fat to metabolically robust beige fat.

Using Salt to Optimize Mental & Physical Performance | Episode 63
I discuss the role of salt (sodium) in the nervous system and the key role that it plays in mental performance, physical performance and health. I explain how the brain senses salt levels in our body and how that relates to our feelings of thirst. I cover the physiology of the renal system and the hormones that control sodium and water balance in our body. I also explore how salt interacts with stress and our immune systems and its crucial role in neuron function. Additionally, I examine research findings suggesting that some individuals might benefit from increased intake of sodium and other electrolytes (magnesium and potassium) to enhance mental performance, lessen anxiety, and offset dizziness. Yet, other people may need less sodium. I discuss how you can determine your optimal sodium intake and why sodium intake levels need to be uniquely tailored to an individual’s lifestyle. Finally, I explain how salt creates ‘hidden’ sugars in many processed foods and the problems that can create. Throughout the episode, I explain peer-reviewed findings outlining salt’s essential role in overall health and describe general recommendations and tools anyone can use to find their optimal salt balance and thereby enhance their brain and body’s performance.

Dr. Justin Sonnenburg: How to Build, Maintain & Repair Gut Health | Episode 62
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.

How to Enhance Your Gut Microbiome for Brain & Overall Health | Episode 61
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.

The Science of Love, Desire and Attachment | Episode 59
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.

Using Play to Rewire & Improve Your Brain | Episode 58
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.

Dr. Alia Crum: Science of Mindsets for Health & Performance | Episode 56
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.

The Science of Setting & Achieving Goals | Episode 55
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.
