EP409: 10 Good Things About Sauna

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Episode Summary Introduction: Dr Warrick Bishop, a cardiologist, author, and CEO of the Healthy Heart Network, explores the surprising health benefits of regular sauna use. After a recent sauna experience on a boat in Tasmania's Derwent River, Dr Bishop dives into 10 evidence-based reasons why saunas are beneficial for overall health and longevity. The episode emphasizes how sauna use complements a heart-healthy lifestyle by addressing cardiovascular, metabolic, and mental wellness. Key Takeaways: Regular sauna users have lower risk of heart attack and stroke due to heat mimicking moderate exercise by increasing heart rate, circulation, and vasomotor response in arteries. Saunas lower both systolic and diastolic blood pressure in people with mild hypertension by improving endothelial function and promoting vasodilation. Sauna use improves insulin sensitivity and glucose metabolism, reducing insulin resistance and inflammation in the body. Post-workout sauna sessions accelerate muscle recovery and reduce soreness, potentially through improved circulation and increased growth hormone levels. Regular sauna use is associated with reduced risk of Alzheimer's disease and dementia through reduced inflammation, improved blood flow, and increased brain-derived neurotrophic factor (BDNF). Saunas induce heat shock proteins that repair damaged cells and protect against cellular stress, contributing to cellular resilience and longevity. Sauna use reduces chronic inflammation by lowering high-sensitivity CRP levels, an important inflammatory marker. Post-sauna core temperature drops trigger natural sleep signals, improving sleep quality and duration. Heavy sweating during sauna may help eliminate heavy metals and environmental toxins, though scientific evidence remains limited. Saunas reduce stress and improve mental clarity, with benefits including relaxation, rejuvenation, and improved cognitive function.
