Episode Details

What if regular heat exposure — saunas, hot baths, even infrared — could strengthen your heart, lift mood, and lower Alzheimer’s risk? (Original episode ~60 minutes → condensed to ~15 minutes.) In this short version of the Dhru Purohit Show, host Dhru Purohit and guest Bill Gifford (author of Hotwired) unpack the epidemiology and biology behind sauna and heat therapy: dramatically lower cardiovascular mortality, a 63% reduced rate of Alzheimer’s in Finnish cohorts, improved sleep, and even rapid antidepressant effects from controlled hyperthermia. You’ll learn practical, science-backed guidance on how to start safely (hot baths, infrared or traditional saunas), why heat shock proteins and improved cerebral blood flow matter for neuroprotection, and how to pair heat with core health pillars like exercise, hydration, and sleep. Topics covered: sauna, heat therapy, Alzheimer’s prevention, cardiovascular health, mood, heat shock proteins, contrast therapy, and practical safety tips.
