Hot and cold therapy, also known as thermotherapy, is the use of heat or cold to relieve pain, reduce inflammation, and improve circulation
Hot therapy works by increasing blood flow to the affected area. This helps to deliver oxygen and nutrients to the tissues and remove waste products. It also helps to relax muscles and reduce pain.
Cold therapy works by decreasing blood flow to the affected area. This helps to reduce inflammation and swelling. It also numbs the area, which can provide temporary relief from pain.
The best type of therapy to use depends on the condition being treated. For acute injuries, such as a sprain or strain, cold therapy is usually recommended. This is because it can help to reduce swelling and pain. For chronic pain, such as arthritis or muscle pain, hot therapy may be more effective.
