Cold Water Immersion (CWI) and Cryotherapy are both forms of cold exposure, though they differ in a few key ways. Cryo works by super chilling the air in the chamber using a gas such as liquid nitrogen whereas CWI uses just water. Because water is a better conduit of heat than air, the effect is that CWI has a significantly faster impact on the body than Cryo. Additionally, with CWI you are able to get your hands, feet, and head under the water for important benefits, whereas with Cryo, your hands, feet, and head are covered. With CWI you are also receiving various benefits of hydro-therapy that water immersion brings. Cryotherapy is typically done in a studio setting and requires very expensive equipment, whereas CWI you can do at your home or in nature.
