Heat therapy involves raising the temperature of a specific area, which can enhance blood flow and circulation to that region. This slight temperature increase can help alleviate discomfort and to improve muscle flexibility. Heat therapy is also known to promote muscle relaxation and soothe any damaged tissue.
The application of cold therapy can result in a reduction of blood flow to a particular region., effectively decreasing inflammation and swelling that cause pain, especially around joints or tendons. This therapy can also temporarily reduce nerve activity, providing pain relief.
