This is a"dry sauna." This means that there is not a breathing problem often associated with a "wet" sauna. The dry sauna only heats the tissue of your body...not the air in the sauna seating area. The infrared heating element is like that used in hospitals' premature baby-care areas...it's very safe and good for you. You sweat out toxins through your skin. Your muscles get softer and ready to receive massage therapy.
