Whole body cryotherapy (WBC) involves exposing individuals to extremely cold dry air (below -100 °C) for one to three minutes. WBC draws from age old techniques like cold water immersion, ice baths, or ice packs to help heal, repair or rejuvenate your muscles. To achieve the subzero temperatures required for WBC, two methods are typically used: liquid nitrogen and refrigerated cold air. During these exposures, individuals wear minimal clothing, which usually consists of shorts for males and shorts and a crop top for females. Gloves, dry socks and boots are commonly worn to reduce the risk of cold-related injury.
