Infrared light (experienced as heat) is the invisible part of the sun's spectrum with the ability to penetrate human tissue, giving a smoothing, natural warmth. It is naturally occurring from the sun and is the basis for Sunlighten sauna therapy.
Sunlighten's solocarbon infrared technology is theraprutic because 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.
