While undergoing whole body cryotherapy, the body pulls the blood away from the extremities and into the core therefore the extremities must be protected. The vessels around the core then constrict, moving the blood into the body’s core. The body then begins working to protect and boost the vital organs, producing and releasing nutrients, such as anti-oxidants into the blood. This is why most people notice very little discomfort in their chest, stomach and back area. The body is producing heat as well to protect the core.

Extra benefit: Blood in the core will more rapidly circulate through the liver – allowing for an additional benefit – detoxification!
