Do Home Saunas Really Work?

Numerous long-term scientific studies say yes! Giordano points to one Finnish study, in particular, from researchers at the University of Eastern Finland, published in JAMA Internal Medicine in 2015. It followed more than 2,000 middle-aged men over the course of about 20 years, concluding a list of incredible health benefits through regular sauna use.

These included lower blood pressure, decreased risk of dementia and Alzheimer’s disease, and decreased risk of respiratory diseases (e.g., things like pneumonia and chronic obstructive pulmonary disease/COPD). Giordano specifically notes a reduced risk of fatal cardiovascular events (e.g., sudden cardiac death, cardiovascular disease, coronary heart disease, and all-cause mortality), too. Most notably the risk of these CV events decreased as the frequency and duration of sauna sessions increased (e.g., twice weekly for 20 minutes per session to four times weekly for 20 minutes per session).
