Infrared is the band of light we perceive as heat. We
cannot see this band of light with the naked eye, but we can feel this type of light in the form of heat. Our sun produces most of its energy output in the infrared segment of the spectrum. Infrared rays heat your body without having to heat the air in-between, through a process called conversion.
The infrared is divided into 3 segments by wavelengths, measured in microns; near infrared: 0.76~1.5 microns; middle infrared: 1.5~5.6 microns; and far infrared: 5.6~1000 microns. Among these segments, only far infrared penetrates organic substances such as the human body so that the warming effect is very uniform.
Infrared Saunas differ from traditional saunas as it uses infrared energy to directly penetrate into the bodys tissue up to 1.5 inches to produce sweating.
Traditional saunas use steam to heat the air inside the sauna, which then heats your body until you begin to sweat. In order for this to be effective, temperatures must reach upwards of 190 Fahrenheit. Infrared saunas only need a temperature of up to 120 Fahrenheit to obtain the same effect. These lower temperatures make the environment more tolerable, while also allowing you to breath easier.
Infrared energy is not only safe, but is also highly beneficial for our bodies. Far Infrared lamps are actively used for medical treatments by physicians and chiropractors, as well as physical and massage therapists.
