De-stress · Brain health technique
Sauna / Heat Therapy
Evidence grade: Context Dependent
Periodic use of dry or steam heat (e.g., Finnish sauna, infrared sauna) to raise core body temperature and induce controlled hyperthermia, followed by gradual cooling.

How to practice Sauna / Heat Therapy
Begin with 1–3 sessions per week, 10–20 minutes at 160–180°F (70–82°C), followed by a cool-down period. Work your way up to 4+ sessions per week at 180F (dry) for 20 minutes - consistent with the highest benefit cohort in the Finnish studies. Hydrate well and avoid alcohol or dehydration. Those with cardiovascular disease should consult a physician before regular use. Consistency and gradual adaptation matter more than duration extremes. Avoid extreme heat - at least one observational study showed increased dementia risk in 200F+ heat.
The evidence behind Sauna / Heat Therapy
Regular sauna use is linked to lower cardiovascular mortality, reduced dementia risk (65% lower risk in highest benefit cohort), and improved mood in large Finnish cohorts. Mechanistically, heat stress increases circulation, induces heat-shock proteins, and mimics mild exercise effects on vascular and autonomic function. Evidence observational but consistent and biologically plausible.
