A new study found that using the sauna was associated with a decrease in a biomarker of inflammation (CRP) in a dose-dependent manner. The more frequent the sauna use…the more robust the effect of lowering inflammation. This study was published early this year from with one of the world’s leading sauna researchers, Dr. Jari Laukkanen.
He has also shown dose-dependent effects with sauna use on cardiovascular disease, all-cause mortality, and Alzheimer’s disease. Using the sauna 2-3 times per week (20 minutes at 174º F) was associated with: 27% lower cardiovascular disease risk, 24% lower all-cause mortality, and a 20% lower risk of Alzheimer’s disease compared to men that only used the sauna one time per week. Using the sauna 4-7 times per week (20 minutes at 174º F) was associated with: 50% lower cardiovascular disease risk, 40% lower all-cause mortality, and a 66% lower risk of dementia and a 65% lower risk of Alzheimer’s disease compared to men that used the sauna once a week.
