CRYO PGH, Pittsburgh

It seems there's almost nothing cryotherapy can't do. The blast of frigid air encourages injured muscles to heal, amps up energy levels, and may speed recovery time in athletes. It even has cosmetic applications. Fans of the frosty practice laud its ability to fade blemishes and help manage weight.

At CRYO PGH, cryotherapy veterans and first-timers alike enjoy a private, spa-like cryotherapy experience. It starts in the lobby, where a chic, contemporary design scheme and a friendly receptionist greet each guest. Next, it's into the treatment room, where visitors change into plush terrycloth robes of cobalt and white. Then, the real action takes place in the cryo-sauna itself, a standing chamber that plummets guests in sub-zero temperatures during the 2–3 minute session.
