“REM sleep occurs 70 to 90 minutes after a person first falls asleep and is essential for emotional well-being. On the other hand, deep, slow-wave sleep, which occurs during non-REM periods, provides a homeostatic recalibration of blood pressure, an essential element of cardiovascular health.”

“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.”

“Although whole-body hyperthermia and sauna use share some similarities, whole-body hyperthermia sessions are typically longer (an hour or more) and the participant's head is spared (often kept cool with ice or cool cloths), prolonging the participant's tolerance to the intense heat.”

“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.”

“When most people think about certain lifestyle factors that affect insulin sensitivity and blood glucose levels, they think about macronutrient composition, or calories, or fasting, or exercise (and lack of), but they don’t often think about sleep.”

“Prolonged endurance exercise, heavy sweating, sauna use, and a minimally processed diet can also increase the practical need to replace electrolytes, which is different from routinely adding large doses for a sedentary person eating processed foods.”

“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.”
