What is Cryotherapy?
Cryotherapy (or cold therapy) is the use of low temperatures for medical purposes. It’s often used for reducing pain and inflammation—the kind that comes with sprains, pulled muscles, injured ligaments and strained tendons. It’s an easy, inexpensive way to get targeted, noninvasive pain relief.

Your perception of pain is regulated by nerve cells. Nerves carry pain signals from receptors in the skin to the spinal cord, and eventually to the brain where pain is perceived.

When you apply cold therapy over a painful area, a different sensation is sent to the brain. This time, as signals travel from the skin to the spinal cord, the cold sensation blocks the pain signal from reaching your brain. As a result, your perception of pain is blocked.
