Cold therapy, also known as cryotherapy, involves applying cold temperatures to the body to reduce pain and inflammation. This method is commonly used for injuries, such as sprains or strains, and can help numb the affected area, providing relief. Cold packs, ice baths, and cold compresses are typical tools used in this treatment. The benefits of cold therapy include decreased swelling and improved recovery time after physical activity. It is often recommended for athletes and individuals recovering from surgery. However, it is essential to use cold therapy safely to avoid skin damage or frostbite, ensuring that ice is not applied directly to the skin.
