#099 The Science of Exercise for Cancer | Kerry Courneya, PhD 03/03/2025

#099 The Science of Exercise for Cancer | Kerry Courneya, PhD For decades, exercise was considered an optional part of cancer care—something beneficial for general health but not essential. The evidence is now overwhelming: exercise is not just supportive—it’s a therapeutic intervention that recalibrates tumor biology, enhances treatment tolerance, and improves survival outcomes. With over 600 peer-reviewed studies, Dr. Kerry Courneya's work has fundamentally reshaped our understanding of how structured exercise—whether aerobic, resistance training, or high-intensity intervals—can mitigate treatment side effects, enhance immune function, and directly influence cancer progression.

#096 How to Improve Metabolic Health with HIIT, Circadian-Timed Eating, & Sleep 10/08/2024

#096 How to Improve Metabolic Health with HIIT, Circadian-Timed Eating, & Sleep Exercise, meal timing, and sleep are three powerful tools for optimizing metabolic health, a key factor in healthy aging. Even slightly elevated blood glucose levels, but within the "normal" range, can contribute to brain atrophy in areas linked to aging and neurodegeneration. Long-term glucose elevations (high HbA1c) also promote harmful compounds that stiffen blood vessels, reduce heart flexibility, and raise cardiovascular risk. In this episode, recorded at the American Academy of Anti-Aging Medicine conference in Palm Beach, Florida, I provide practical, science-backed protocols on how to implement HIIT, circadian-timed eating, and optimized sleep strategies to dramatically improve metabolic health and protect against these harmful effects.

#095 What Microplastics Are Doing to Your Brain, Body, and Reproductive Systems 09/19/2024

#095 What Microplastics Are Doing to Your Brain, Body, and Reproductive Systems Every week, the average person ingests the equivalent weight of a credit card in plastic.* While certain preventive measures can significantly reduce your intake of these harmful substances, it’s crucial to acknowledge a more daunting concern: the bioaccumulation of microplastics in the brain, potentially at ten times the rate of other organs. Microplastics and their associated chemicals are alarmingly ubiquitous — they permeate breast milk, sperm, the hippocampus, the prefrontal cortex, the air we breathe, medications, the water supply, and our bloodstream, accumulating in most major organ systems. During this episode, we’ll explore the unsettling realities of microplastics and their associated chemicals, diving into how they infiltrate nearly every facet of our environment and body, and discuss actionable strategies to reduce exposure.

#080 How Heat Therapy Improves Slow Wave Sleep 05/30/2023

#080 How Heat Therapy Improves Slow Wave Sleep Heat therapy, such as using a sauna or soaking in a hot bath, may significantly improve your slow wave sleep. My latest episode delves into the fascinating intersection between exercise and passive body heating and elucidates how high energy expenditure exercise and heat exposure share nuanced mechanisms in sleep regulation. Some key aspects explored include: The surprising role of the immune system in regulating sleep through somnogenic cytokines, immune signals like IL-1B and TNF-alpha, released in response to heat stress and exercise. The interconnected nature of thermoregulation and sleep, particularly in the brain, which highlights the importance of overlapping sleep regulation and heat loss processes. This involves warm-sensing preoptic area neurons in the preoptic area of the hypothalamus, a region known to play a crucial role in sleep regulation. The intricate, bidirectional relationship between growth hormone (GH) and slow-wave sleep (SWS). With the majority of daily GH secretion occurring during the initial phase of SWS, stimulants of SWS, such as heat exposure, can result in enhanced GH secretion, establishing a strong connection between GH and sleep regulation. The varying influence of heat on growth hormone, ranging from doubling after two 20-minute sauna sessions at 80°C, to increasing its circulation up to 16-fold after two one-hour sauna sessions at 80°C. These findings highlight the potential for heat therapy and exercise with a high rate of energy expenditure to modulate slow wave sleep through the interconnected nature of thermoregulation, immunity, exercise, and hormones. By understanding and harnessing these links, individuals can potentially enhance their sleep quality and overall health and well-being. In this episode, I discuss: (00:00) - Introduction (01:06) - Increasing pre-sleep tiredness (02:06) - Effects of exercise (04:09) - How the immune system regulates sleep (05:07) - What heat and exercise have in common (06:39) - Hormonal effects of heat (06:59) - Growth hormone (09:26) - Prolactin and sleep onset (10:39) - Effect of sexual activity (12:08) - Overlap in the brain (thermoregulation vs. sleep) (12:46) - Heat protocols and tactics Join over 300,000 people and get the latest distilled information straight to your inbox several times per month: Become a FoundMyFitness premium member to get access to exclusive episodes, emails, live Q+A’s with Rhonda and more: Learn more about the premium podcast The Aliquot: /episode/index/show/foundmyfitness/id/26989089

#073 Sauna Benefits Deep Dive and Optimal Use with Dr. Rhonda Patrick & MedCram This episode features a discussion with MedCram co-founder Kyle Allred on the effects of sauna. I had the pleasure of being interviewed by Kyle on all things sauna science and we're posting that discussion for you here. As an exercise mimetic, sauna use has anti-inflammatory, mood-elevating, and detoxifying properties that research increasingly shows may deliver cardiovascular and brain benefits. The science of sauna use has been a research interest of mine for many years and this discussion is by far one of the most well-rounded discussions I've had on the subject. Thanks to Kyle and MedCram for having me for his interview. In this episode, we'll discuss: (00:00) Introduction (02:46) Summary of sauna benefits (10:47) Heat as an aerobic exercise mimetic (14:45) Effects of heat acclimation on endurance (17:37) Why heat shock proteins may protect against dementia (23:20) The stress-relieving effects of sauna use (personal anecdote) (27:43) Investigating sauna for depression (30:32) Brain-derived neurotrophic factor (BDNF) and endorphins response (34:51) Cellular repair mechanisms elicited by sauna use (40:05) Prevention of muscle atrophy (42:45) Detoxification of heavy metals (44:50) Heart rate variability, a measure of stress resilience (46:40) The synergy of sauna use and exercise (52:13) Cross-cultural and historical prevalence of heat therapy (56:12) Infrared sauna vs. traditional saunas (58:31) Rhonda's personal sauna protocol: duration, temperature, humidity, and frequency (01:03:22) How jacuzzi, hot baths, and hot showers compare to sauna use (01:06:19) Hydration, cold therapy, and sauna safety (01:11:18) Who should not use saunas? (01:15:21) Does sauna use increase blood sugar levels?
