“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

“While it’s likely that there may be more going on with depression than just inflammation by itself, it could be an incredibly useful lens through which to look at promising avenues to potentially treat or prevent it, since controlling systemic inflammation shows promise as being both important for longevity and health in general.”

“Circulating LPS can also bind to lipoproteins, facilitating their absorption in the liver during LDL recycling, effectively removing LPS from circulation and lowering systemic inflammation – a phenomenon demonstrated mechanistically with statins that increase lipoprotein recycling by increasing LDL receptors.”

“00:34:40 - Repeated traumatic brain injury has cumulative neuroinflammatory effects in the brain over years, including amyloid-beta plaque and tau tangle formation. Study. 00:44:00 - A variant of the APOE gene increases risk of developing Alzheimer’s disease as much as 15-fold.”

“New Scientist article. 02:06:10 - Some people, like Tom Cruise and Keanu Reeves, seem to defy aging. 02:08:15 - One 12-ounce can of sugar-sweetened soft drink per day shortened telomere length, corresponding to 4.6 years of biological aging.”

“People who have poor cardiorespiratory fitness are more likely to be depressed. Sauna improves cardiorespiratory fitness and may offer a means to ameliorate the symptoms of depression and improve mood. In this clip, Drs. Rhonda Patrick and Jari Laukkanen discuss the benefits of sauna use in terms of cardiorespiratory fitness and mood.”
