Infrared light, as radiated by the Sun, lies between the Visible and Microwave sectors of the electromagnetic spectrum.
In an infrared sauna, the infrared heater produces radiant energy, which is the same as the heat from the sun, only without the harmful ultraviolet rays. Most of these heaters draw on technology developed in 1965 by Dr. Tadashi Ishikawa, a member of the Research and Development Department of Fuji Medical.
The experience of a far infrared sauna is similar to sunbathing, which gives you the radiant heat that is all your own. The far infrared heat penetrates your skin, giving you that wonderful natural warmth. Unlike sunbathing, Infrared heat therapy is completely healthy and safe. You can relax in a far infrared sauna and it will never cause your skin to burn. Far infrared heat is completely healthy and safe for all living things. In fact, far infrared heat is so safe it is used in hospitals to warm newborn infants.
