Infrared focuses on first treating the body internally. Infrared light penetrates the skin and increases the body temperature from within. Prepare to sweat, cleanse, and purify not only from your pores, but deep from your cells. Our Infrared sauna use a much milder temperature environment (120-130 degrees F). Because the heat of the infrared sauna penetrates the body's tissues increasing the core body temperature, it's able to cause a more vigorous and detoxifying sweat at lower temperature
