Why it works - The skin is the largest organ of the body. When it is exposed to ultra-cold temperatures, the blood vessels in the skin constrict. This constriction forces the blood to the liver, lungs and heart which detoxify, reoxygenate, and send the blood back to the skins surface. This improves circulation, eliminates toxins and inflammation which leaves you feeling invigorated and refreshed. Repeated treatments or sessions will improve many systems within the body including hormone regulation and metabolism.
