As the human body absorbs infrared heat a natural resonance occurs that causes a warming effect. It is this action that stimulates the bodys blood vessels, thereby increasing circulation by decreasing pressure within the heart. As circulation increases the body will perspire, allowing certain toxic waste to be purged from the body. This action reduces the workload of the kidneys, liver and pancreas as well as other organs within the body.

To gain maximum efficiency as a sauna, the Light of Life utilizes both the Medium and the FAR Infrared Wavelengths. From the Medium Infrared Wavelength, 4 to 5.6 microns are utilized to cause deep heat penetration. The balance of the required heat energy is gained from the Far Infrared Wavelength, 5.6 to 14 microns, with primary output spread evenly around the peak human output level of 9.4 microns. This allows for the higher heat penetration ability of the Intermediate / Medium Wavelength and the resonant absorption amplification of healthy tissue by the longer wave Far Infrared Band.

Scientific research has shown that Qi-Gong Therapy, as practiced in China, utilizes a form of Infrared therapy. Qi-Gong allows for the exchange and boost of the human energy level via special treatments based on the body being composed of water and minerals that emit Infrared at a wavelength between 6 and 14 microns.
