Cryotek, Philadelphia

Lauded live on Dr. Oz for reducing inflammation and helping patients manage pain, Cryotek's Cryosauna envelopes clients in an open-top standup booth that surrounds the body with temperatures up -250 degrees Fahrenheit. Cryotek's researchers believe this exposure to cold—known as cryotherapy—during two- to three-minute sessions delivers many positive effects, including aiding clients with weight loss, cellulite reduction, and injury recovery. They also claim the Cryosauna supports other areas of physiological and even psychological health including reducing inflammation from arthritis, soothing irritation from psoriasis, reducing stress, and restoring libido. An FAQ page addresses queries ranging from what the treatment feels like to how it differs from kissing a snowman.
