Cryo Spa Natural Healing Center uses the low temperature of nitrogen vapor to alleviate the symptoms of everything from arthritis and skin conditions to stress and fibromyalgia. Friendly staffers usher clients into the Cryosauna chamber, which envelops them in a blanket of nitrogen vapor for three-minute intervals. The sub-zero temperature promotes the release of endorphins and anti-inflammatory proteins to improve functions of the immune and metabolic systems. Because there's no humidity in the chamber, the temperature remains comfortable. An onsite massage therapist complements cryotherapy treatments with hot-stone, deep-tissue, and shiatsu massages.
