As soon as you take a seat or lie down in one of our IR saunas, FAR infrared waves begin to penetrate 2 to 3 inches into your body. These waves create a deep heating action, which activates the sweat glands. Sweat glands function in our body to naturally eliminate and expel waste materials and toxins. Since skin is the largest organ in the human body, the deep heating of the sweat glands allow for a deep detoxifying sweat. The human body is comprised of 70% water molecules. FAR infrared waves cause these molecules to vibrate. This vibration reduces the ion bonds and breaks down the water molecules. These molecules often encapsulate gases and other toxic materials
