So no cold plunging and then sauna?

That's probably still very healthy. The study looks at deaths per year at non-optimal temperatures. Living in a desert is different than taking a sauna.

		Yeah, I expect it's pretty similar to how long-term, constant stress is correlated to poor longevity, but frequent bouts of short term stress of intense exercise followed by recovery is correlated with good longevity.
