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; 0.76~1.5 microns-near;1.5~5.6 microns-middle;5.6~1000 microns-far infrared. Among these segments, only far infrared penetrates organic substances such as the human body two to three inches so that the warming effect is very uniform.
Health Mate Sauna's exclusive M-type far infrared heaters radiate this far infrared to safely and effectively warm your body.
