What Is Far-Infrared Heat?
Infrared heat is light produced by the sun. This is the heat you feel penetrate your skin when you
stand in the sun - and miss when you walk into the shade. Infrared energy is also given off as body heat.
The human body can also absorb infrared heat. Infrared energy is measured in wavelengths as microns.
The human body can best absorb infrared energy in the 3- to 50-micron range, with the best absorption occurring at 9.4 microns.
TheraSauna TheraMitters emit infrared heat in the 7- to 14-micron range with a peak at 9.4 microns, the same as the human body, making it easier to absorb.
Easier absorption also means that the infrared heat penetrates deeper into body tissues than traditional hot air saunas - up to an inch-and-a-half.
