How Sauna Use Can Impact Brain Health and Longevity

Dr. Peter Attia and Dr. Rhonda Patrick dig into why sauna keeps showing up in longevity conversations: regular use is tied to lower rates of both cardiovascular disease and dementia, and the two are more connected than people think — better vascular health measurably carries over into better brain function.

One angle they cover is training. Pair sauna with endurance work and you get bigger VO2 max gains than endurance training alone — a small trial found roughly a 6% improvement after three weeks of post-workout sauna sessions.

The mechanism behind a lot of this is heat shock proteins. Sit in a 160–175°F sauna and HSP levels climb sharply, helping cells repair damage and handle future stress better.

Infrared saunas get you similar benefits — expect roughly double the session time to match the cardiovascular effects of a traditional dry sauna, since infrared units run at lower ambient temperatures.
