“In this video, Dr. Rhonda Patrick summarizes a recent study that found that frequency of sauna use was associated with increased decreased risk of death. Using the sauna 2-3 times per week was associated with 24% lower all-cause mortality and 4-7 times per week decreased all-cause mortality by 40%.”

“In this Knowledge Project excerpt, Dr. Rhonda Patrick distinguishes Finnish sauna protocols near 174–175°F from lower-temperature infrared sauna, which may require longer exposure. Dose depends on temperature, humidity, duration, acclimation, hydration, and health.”
Episode
“A staggering 60% of all calories Americans consume come from ultra-processed foods that fail to induce proper satiety, remain cheaper than whole foods, and hijack our dopamine reward pathways, pushing us to overeat, incentivizing unhealthy food choices, and reinforcing addictive eating behaviors.”
Clip
“Exercise promotes the release of insulin-like growth factor-1 and its downstream targets, growth hormone and brain-derived neurotrophic factor, to drive muscle and neuron growth. Sauna use increases these factors, too, and when used post-exercise, may have a synergistic effect to improve cardiovascular, musculoskeletal, and neurological health.”
Episode

Clip
“In a placebo-controlled study of eight healthy adults, adrenaline infusion lowered plasma magnesium, and levels had not recovered one hour later. Investigators proposed a shift into cells after beta-adrenergic stimulation; the study did not measure cortisol, urinary loss, total-body depletion, or clinical deficiency.”
Clip
“During the peak phase, participants sometimes completed two interval sessions per week, while the longer maintenance phase generally used one interval session alongside continuous endurance work and strength training.”
