US Cryotherapy

Often employed by athletes recovering from workouts or injuries, cryotherapy uses subzero temperatures to reduce inflammation, relieve pain, and increase mobility. During each session, up to four guests spend 30 seconds inside an antechamber cooled to -66 degrees Fahrenheit, then 2.5 minutes in a main chamber at -166 degrees Fahrenheit. Though the skin's surface temperature can drop by more than 30 degrees, the treatment's short duration keeps guests' core temperatures at normal levels. Upon exiting the chamber, guests move into an exercise room where they stimulate reparative blood flow by performing a 10-minute cardio workout or visualizing a grocery-store shopper sneak 11 items into the 10-items-or-less line.

US Cryotherapy provides necessary safety gear to keep hands, ears, mouths, and noses warm, and recommends guests come dressed in gym shoes and swimsuits. First-timers must complete a brief physical-readiness questionnaire, which screens for health conditions that may cause complications during cryotherapy sessions or attempts to gain part-time work as an ice sculpture.
