The Science & Process of Healing from Grief
This episode, I discuss grief and the challenges of processing losses of different kinds. I explain the biological mechanisms of grief, including how neural circuits for emotional and factual memory combine with those for love and attachment, to create feelings of absence and yearning. I discuss how grief is distinct from depression, yet why they can feel so similar. I also provide science-based tools to assist with the grieving process, including how to reframe and remap the relationship with those we have lost while still maintaining a strong emotional connection to them. I also explain the importance of having and building strong foundational psychological and biological states so that we can better cope with grief when it happens. Finally, I describe tools to adjust those states, including those for accessing sleep, managing stress and emotional swings. This episode is for those suffering from grief but also for everyone, given that we all experience grief at some point in our lives. We recorded this episode before the recent mass shooting tragedies in the United States. While we hope the information in this episode will be of use to anyone suffering from grief of any kind and at any time, we are also careful to acknowledge that many people require additional support and resources. For that reason, we include mention of such resources and we generally hope people will access them if needed. For the full show notes, visit hubermanlab.com.

Boost Attention & Memory with Science-Based Tools | Dr. Wendy Suzuki
My guest is Dr. Wendy Suzuki, Ph.D., Professor of Neural Science and Psychology and (soon) Dean of New York University, whose research focuses on memory, attention, brain plasticity and simple, daily habits that can be leveraged to improve learning, focus, memory and cognitive ability. We discuss the role of cardiovascular exercise, weight training, deliberate cold exposure, meditation, verbal affirmations, sleep, and other behavioral practices for enhancing learning, mood and stress management, and increasing attention span. Dr. Suzuki shares the mechanisms by which these practices change our brain in order to improve cognitive function fast and reduce age-related cognitive decline.

Understand & Improve Memory Using Science-Based Tools
This episode I explain the mechanisms by which different types of memories are established in our brain and how to leverage the amount and timing of key neurochemicals and hormones, such as adrenaline (aka epinephrine) and cortisol, to improve your learning and memory abilities. I describe multiple science-based protocols to do this, including repetition, caffeine, emotional states, deliberate cold exposure, sleep, meditation, and the role of vision, including taking “mental snapshots.” I also describe how exercise and an associated hormone, osteocalcin, can improve cognitive ability and memory formation. I also describe unique aspects and forms of memory such as photographic memory, extreme facial recognition (aka super recognition), and the phenomenon known as déjà vu.

Understanding & Controlling Aggression
This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones—estrogen and testosterone—in mediating violent and and/or competive aggression. I also describe tools that can be used to modulate the factors that have been shown to ‘prime’ an individual for aggression, including sunlight, estrogen sensitivity, competition within social settings, and overall stress levels, and the hormone cortisol. I discuss how substances such as caffeine and alcohol can impact impulsive behaviors, and how nutrition and supplementation can be used to regulate mood and aggression.

Micronutrients for Health & Longevity | Dr. Rhonda Patrick
My guest is Rhonda Patrick, Ph.D. She earned her doctoral degree in biomedical science from St. Jude Children’s Research Hospital at the University of Tennessee Health Science Center and has become one of the leading public health educators on the brain and general health, aging, cancer, and nutrition. We discuss the four major categories of micronutrients that regulate cellular and organ stress and antioxidants, inflammation, hormone regulation, immune system, and longevity. Dr. Patrick provides actionable protocols for obtaining key micronutrients from food and/or supplement-based sources. Additionally, Dr. Patrick outlines protocols for deliberate cold and deliberate heat exposure to benefit metabolism, cardiorespiratory fitness, mental health, and lifespan.

The Science & Health Benefits of Deliberate Heat Exposure
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 Light (Sunlight, Blue Light & Red Light) to Optimize Health
I describe the mechanisms by which different wavelengths of light impact the cells, tissues and organs of the human body, and how specifically timed light exposure of specific wavelengths can be used to improve sleep, enhance alertness, modulate hormone levels, and improve mood. I also explain the use of ultraviolet and infrared phototherapies to relieve pain increase testosterone and estrogen levels; improve skin health, appearance and wound healing; and how red light can be used to offset age-related vision loss and provide neuroprotection. Throughout the episode, I describe the mechanisms of light-based therapies and actionable tools that people can use positively impact mental and physical health.

How to Optimize Your Hormones for Health & Vitality | Dr. Kyle Gillett
My guest is Dr. Kyle Gillett, MD, a dual board-certified physician in family medicine and obesity medicine and an expert in optimizing hormone levels to improve overall health and well-being in both men and women. We discuss how to improve hormones using behavioral, nutritional, and exercise-based tools and safely and rationally approach supplementation and hormone therapies. We discuss testosterone and estrogen and how those hormones relate to fertility, mood, aging, relationships, disease pathologies, thyroid hormone, growth hormone, prolactin, dopamine and peptides that impact physical and mental health and vitality across the lifespan. The episode is rich with scientific mechanisms and tools for people to consider. For the full show notes, visit hubermanlab.com.
