Sunlight contains all the colors of the rainbow, plus a number of invisible forms of light, including the infrared and ultraviolet spectrum. The infrared spectrum of light is quite large. Research has found that human beings produce infrared heat in the “far infrared range,” centered at 9.4 microns. Infrared heat in this range of wavelength is the most natural and the healthiest for the body. This wavelength of infrared heat penetrates in the tissue up to 1 ½ inches and begins a process of expelling stagnant substances that have accumulated in the body.

This infrared frequency range that’s both produced by the body and comprises the healthy rays of sunlight, is experienced in Clearlight^® infrared saunas. This penetrating heat gently raises the body’s core temperature and allows the body to detox naturally via the process of sweat, through the largest organ of the body – the skin. In addition, on a cellular level, the body feels the same elevated circulation, warmth, and energy that is usually felt only from exercise.
