Whole body cryotherapy uses a state of the art machine called the Cryosauna which simulates the same benefits of old with a whole new level of cold in just three minutes. The cryosauna uses cryogenic nitrogen vapor to lower the temperature as much as -120ºC (-184ºF). Your skin reacts to the cold and sends messages to your brain which activates anti-inflammatory molecules and endorphins, increases oxygen in the blood and releases toxins.
