This sauna uses far-infrared radiant heat (FIR). It is a form of light not visible to the human eye that can be felt as heat. Unlike conventional saunas that need to heat the air,  far-infrared sauna heat warms the body directly though direct light conversion. The infrared sauna allows for the heat to penetrate into the body quicker and have greater therapeutic effects. The heat increases circulation to promote oxygen and nutrients in the blood to nourish damaged tissues. The skin is an organ that the body is able to eliminate toxins from. Improving blood flow and eliminating toxins can help with many different health conditions including weight loss, muscle tension, chronic pain conditions, and skin conditions. It also helps to boost the immune system and provides a deep sense of relaxation.
