Devices designed for whole-body cryotherapy utilize extremely cold air, typically delivered within an enclosed chamber, to rapidly cool the body’s surface. This process usually involves brief exposures, often between two and four minutes, to temperatures ranging from -110C to -140C. An example is a cryosauna, which resembles a stand-up tanning booth and exposes individuals to nitrogen vapor.
Whole-body cryotherapy is pursued for several potential benefits, including reduced muscle soreness and inflammation, improved recovery times after strenuous physical activity, and potential relief from certain types of pain. Historically, localized cold therapy has been used for centuries to manage inflammation and pain. The application of this concept to whole-body exposure is a more recent development, gaining popularity in athletic training and recovery protocols. Further research is ongoing to fully understand the physiological effects and long-term benefits of this practice.
