Sauna bathing and mortality in the Finnish KIHD cohort
Who, how long
2,315 Finnish men (42–60), 20.7 years
What they found
4–7 saunas a week: –50% cardiovascular death and –40% all-cause mortality versus once a week; sessions over 19 minutes were better.
⚠ Caveat
Men only; frequent sauna-goers may be wealthier and healthier; no RCT.
