Multifaceted Benefits of Passive Heat Therapies: Finnish Sauna Review
Do Finnish saunas extend healthspan?
Yes. Regular Finnish sauna use significantly reduces the risk of cardiovascular disease, dementia, stroke, and all-cause mortality, contributing to extended healthspan. A comprehensive review published in Temperature synthesizes evidence showing that frequent sauna bathing (4-7 times per week) reduces hypertension risk by approximately 47%, stroke risk by approximately 62%, dementia risk by approximately 66%, and cardiovascular mortality.
Passive heat therapy works by improving cardiovascular function similar to moderate exercise, enhancing production of protective heat shock proteins, reducing systemic inflammation, improving insulin sensitivity, and supporting mental health through endorphin release and stress reduction.
