Cryotherapy works by lowering the skin temperature of the body very rapidly and for a short period of time (2 to 3 minutes). This dramatic but brief reduction in the body’s temperature causes the release of a sudden burst of adrenaline, giving an immediate boost to the body’s immune system. This immune system improvement can last for days or even weeks after the treatment. There is also a short term release of endorphins, the body’s natural pain killer. This change in physiology within in the body can result in accelerated healing and promote increased well being in all the body’s organs, cells and systems.
