A sauna benefits your heart health, as long as you practice sauna safety
Are saunas good for you? Sweating is an impulse that goes far back in human history. About 3,000 years ago, the Mayans of Central America used sweat houses for religious ceremonies and good health. Nearly every culture has its own way of using heat for relaxation, therapy and ritual; ancient Roman baths, modern Turkish steam baths, and trendy American hot tubs are but a few examples.
One of the oldest — and hottest — of these techniques is the sauna. Saunas have been used for thousands of years in Finland, where nearly a third of all adults take them regularly. And saunas are increasingly popular in the United States, where over one million are in use.
Popularity is one thing, safety is another. Are saunas good for your health, or can they be harmful?
