Sitting in a sauna for just 15 to 30 minutes can burn 1.5 to 2 times as many calories as anywhere else. So the average 150-pound woman loses about 68 calories per 30 minutes in the sauna.
To take full advantage of the weight loss benefits associated with saunas, you should start with 15- to 20-minute sessions a few times a week and gradually increase to daily sessions. The easiest way is to invest in a sauna for your home.
A sauna can help you burn some extra calories, but don't just sweat it out to lose weight. It is not an effective tool for real weight loss.
The heat of the sauna can cause you to burn calories long after your workout. It does this by speeding up your metabolism. This boost will last for hours after you leave the sauna. Heat also makes your heart beat faster.
It is recommended to do a sauna three times a week, and each sauna should not exceed 45 minutes.
