This podcast episode explores the profound impact of heat exposure on sleep quality. Heat, through methods like warm baths, saunas, or exercise, promotes sleep onset and increases slow wave sleep. It triggers the release of ATP, adenosine, and sleep-regulating cytokines. Notably, exercise combined with heat exposure amplifies these benefits, leading to increased growth hormone and prolactin, hormones crucial for restorative sleep. Passive body heating techniques also offer non-pharmaceutical solutions for sleep disturbances, particularly in the elderly population.
