Sauna Hype goes back to the papers.

Heat and cold went mainstream in the 2020s. Podcasts turned small studies into daily protocols, and brands built product pages on top of those protocols. Each retelling let the numbers drift a little further from the paper.

Sauna Hype is a science publication about that drift. We trace each claim to the study it came from and read the study in full wherever we can get it. Then we give the claim a reading on the Hype Dial and link every figure to its source.

Plenty of what people say about saunas stands up well. The Finnish studies that followed men for twenty years found large associations, and newer trials keep adding to them. Cold water gets more hype than the sauna on a much thinner record.
