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.
the use of sauna for sake of growth hormone release. ... you could do 20 minutes, then get out of the sauna for 10 minutes, and just cool off at room temperature, and then get back into the sauna, then get out, and then shower, dry off, and head to bed.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

if you want to get the greatest growth hormone increases, do sauna or other deliberate heat exposure fairly seldom, probably no more than once per week, maybe even less, and do it a lot that day.
So, there is a specific sauna protocol that can allow you, can allow anybody, in fact, to increase the amount of growth hormone released into their brain and body 16 fold. That's right, 16 fold. However, it involves shifting from a hot environment to a cool environment, to a hot environment, to a cool environment, over and over and over again, over a very short period of time, because it engages a switch, a process, that compounds, it builds on itself, to increase growth hormone further and further.
one study in particular, that discovered certain forms of deliberate heat exposure using sauna can stimulate very large increases in growth hormone output, which for people in their 30s, 40s, and beyond could be very useful, and may also be useful for people who are just trying to stimulate the release of more growth hormone in order to, for instance, recover from exercise or stimulate fat loss or muscle growth or repair of a particular injury.
heat, this is a study out of Finland, showed that you get massive, even 16 fold increases in growth hormone, which are extremely beneficial for metabolism and for recovery.
So these massive increases in growth hormone are seen when you are doing these sessions of sauna that are repeated on the same day and you're only doing that about once a week.
entering environments with where it's very hot for short periods of time anywhere from 20 minutes to 30 minutes where the temperature is 80° C to 100° C has been shown to increase growth hormone release 16 fold that's right 16-fold that's 1, 1600%

and that you would want to time that to other events in your life, maybe hard workouts or if you're trying to push through a fat loss barrier or simply in order to access growth hormone at peak levels, maybe three times per month or four times per month.
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.
