One of the most common benefits of a sauna is weight control. Sweating away in a sauna after a hard workout will help you burn a few extra calories.
Any kind of sauna – infrared, dry, or steam -- will heat the body and therefore raise your heartbeat and metabolism. By raising your metabolism, your body burns calories quicker and more effectively. You can burn up to 300 calories in a 20 minute sauna session, the same number of calories as a short jog or a long walk burns. Dry saunas elevate your metabolism more than a wet sauna, because they use higher temperatures. Therefore you will burn calories quicker and in a shorter amount of time using a dry sauna.
