What the evidence says

Laukkanen cohort: 4-7 sessions/week associated with 40% reduction in all-cause mortality and 63% reduction in sudden cardiac death vs 1x/week. Observational data only — no large RCT.

Mechanism

Heat stress induces heat shock proteins; cardiovascular training effect (HR up to 150 bpm); endothelial function; mild hormesis; possibly mimics moderate exercise

Studied, labeled, or reported dose & route

4-7 sessions/week at 80-100°C for 15-20 min — based on highest-benefit Kuopio cohort data

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
