As you relax in the gentle far infrared heat, your body is actually hard at work producing sweat, pumping blood, and burning calories. As your body increases sweat production to cool itself, your heart will work harder to pump blood at a greater rate to boost circulation. This increase in your metabolism will burn calories.
According to the Journal of the American Medical Association, "Many of us who run do so to place a demand on our cardiovascular system, not to build big leg muscles. Regular use of a Sauna imparts a similar stress on the cardiovascular system, and its regular use may be as effective a means of cardiovascular conditioning and burning of calories as regular exercise."
Day Spas and Medi-Spas around the world are using Infrared Saunas more and more to help eliminate cellulite. Since the far infrared radiant heat of the sauna warms three times as deep as conventional saunas, it is significantly more effective at reducing cellulite.
