Cryotherapy is the practice of applying ice, usually wrapped in a towel or other material, to the skin. This method is used to reduce inflammation and swelling, alleviate pain, and control bleeding.
The decrease in temperature causes the blood vessels to narrow, resulting in reduced blood flow.
Ice-packs serve as a pain relief method for various conditions, including intense headaches. They are commonly applied to sports injuries to reduce swelling and bruising. Additionally, ice-packs can be utilized to aid in stopping bleeding from small vessels, such as in the case of a nosebleed.
