Infrared light (experienced as heat) is the invisible part of the sun’s spectrum with the ability to penetrate human tissue, giving a soothing, natural warmth. It is naturally occurring from the sun and is the basis for our infrared sauna therapy. Sunlighten's saunas have Solocarbon® infrared technology that is therapeutic: It is 95-99% efficient at heating the body directly rather than simply heating the air. It works to raise the core body temperature to produce a deep, detoxifying sweat at the cellular level where the majority of toxins reside.
Infrared heat is completely safe and healthy for all living things. You can be exposed to infrared light for hours without the risk of burning. Infrared is a naturally occurring output of the sun but does not contain the harmful UV rays associated with unprotected sunlight. It's even used in hospitals to warn newborns.
Infrared is part of a natural spectrum consisting of 3 wavelengths: near, mid and far. You will have the chance to choose a program based on your health goals that will optimize the wavelength in the program.
