Far Infrared is thought to be 7 times more effective at detoxifying heavy metals such as mercury, aluminum, and even cholesterols, nicotine, alcohol, ammonia, sulfuric acid and other environmental toxins, as opposed to conventional heat or steam saunas.

The human body is a reservoir of all kinds of bio-toxins which cannot be expelled immediately and become stored in the body, thereby triggering illness. When toxic gases such as sulphur dioxide and carbon dioxide, or potentially fatal heavy metal toxins such as mercury, lead and chlorine, meet large water molecules, they are encapsulated by clusters of water and trapped in the body. Where these toxins are accumulated, blood circulation is blocked and cellular energy is impaired. However, when a 7 to 14 micron FIR wave is applied to these large water molecules, the water begins to vibrate. This vibration reduces the ion bonds of the atoms which are holding together the molecules of water. As the water evaporates, the encapsulated gas and toxins can be released.
