Long-running Finnish cohort studies have linked frequent sauna use to lower cardiovascular mortality and possibly to lower dementia risk.
What seems to matter
Frequency (4–7 sessions/week was the strongest signal), duration (15–30 minutes), and temperature (80–90°C / 175–195°F in traditional dry sauna).
How to start
Begin with 10 minutes and build. Hydrate generously. Avoid alcohol around sauna. Skip if you have uncontrolled cardiovascular disease unless cleared by a clinician.
