The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
Sauna also increases prolactin, which repairs nerve damage
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Prolactin. In one study, um, men that used the sauna, they were in the sauna for an 80° uh, Celsius sauna until they felt exhausted. They had a t-fold increase in prolactin levels.
Regular sauna use is probably one of the most powerful stimuli that increases both growth hormone and prolactin.
And similar to growth hormone, prolactin levels lasted for a couple of hours.
In another study, women who did a 20inut dry sauna twice a week had a 510% increase in prolactin levels after each sauna session.
4–7 sauna sessions per week, 20 minutes at 80°C+, reduce cardiovascular mortality risk by 40% over a decade.
Regular sauna use raises BDNF and improves verbal memory in older adults.
Sauna protocols only generate the longevity effect when sessions exceed 30 minutes.
Hot-tub bathing yields cardiovascular benefits comparable to traditional Finnish sauna at matched core-temp dose.
