Cryotherapy is the use of cold to aid in recovery of an injured or inflamed area.
Applying cold to an injury produces two important effects. It helps relieve pain, and it reduces swelling. Cold slows down nerve activity, which creates a numbing effect and reduces the sensation of pain. It also does it without any of the side effects that prescription or OTC medications might cause.
Cryotherapy also helps reduce swelling and slows down cellular metabolism, which allows your body to heal faster. Excess swelling can impede the healing process and also contributes to uncomfortable pressure pain. Slower cellular metabolism means less cell death and therefore less tissue for the body to repair.
