The famous 20-Year study on sauna use

There have been Finnish studies suggesting that regular sauna use may have positive effects on various health outcomes, including mortality rates. Research conducted in Finland, where saunas are deeply ingrained in the culture, has provided valuable insights into the potential benefits of sauna bathing. Here are some key findings:

1. Cardiovascular health: A study published in JAMA Internal Medicine in 2015 examined the association between sauna use and cardiovascular disease (CVD) risk. The study followed over 2,300 middle-aged Finnish men for an average of 20 years. The results showed that frequent sauna bathing (4-7 times per week) was associated with a significant reduction in the risk of fatal CVD events, coronary heart disease, and all-cause mortality compared to those who used the sauna once a week or less.

2. Lower blood pressure: Another study published in the European Journal of Epidemiology in 2017 found that regular sauna bathing was associated with lower blood pressure levels. The study followed over 1,600 middle-aged Finnish men and women for an average of 14 years. The results indicated that frequent sauna bathing was associated with a decreased risk of hypertension and lowered blood pressure levels over time.

3. Reduced overall mortality: A study published in JAMA Internal Medicine in 2018 further explored the association between sauna use and all-cause mortality. This study followed over 2,300 Finnish men for a median follow-up period of around 20 years. The results showed that regular sauna use (2-3 times per week) was associated with a lower risk of all-cause mortality, including deaths related to cardiovascular events and other causes.

These Finnish studies suggest that regular sauna use, particularly several times per week, may be associated with a reduced risk of cardiovascular events and overall mortality.
