Dr. Wendy Suzuki: Boost Attention & Memory with Science-Based Tools

I explain how to blunt sugar cravings through fundamental knowledge of how sugar is sensed, metabolized, and utilized within the body. I explain how sugar is processed through the digestive tract and nervous system and how both the taste and nutritive components of sugar can lead to specific appetite changes and cravings. I discuss the connection between sugar, dopamine, and cravings and outline many tools to curb sugar cravings, specifically craving highly processed refined sugars.

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.

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.
