Far-infrared is part of the sun’s invisible light spectrum that is essential to plants, animals, and humans.
Infrared heat is a form of energy that penetrates the body by warming muscles and tissue directly without heating the air. Infrared energy keeps us warm and repairs body tissue. The human body absorbs infrared in the 3 to 50 micron range. Light waves between 6 to 14 microns have special regenerative effects on the body, with the optimum absorption by the human body occurring at 9.4 microns.
QCA Saunas use the Patented Stable Heat™ System, which is able to consistently reach this important bench mark of far-infrared light.
