How it works:
Heat therapy interacts with the body to alleviate pain associated with muscle and tissue strain or damage. Heat therapy dilates the blood vessels of the muscles to increase the flow of oxygen and nutrients to the muscles helping to heal damaged tissue.
Heat stimulates the sensory receptors in the skin, which means that applying heat to the affected area will decrease transmissions of pain signals to the brain and thereby relieve the discomfort. Consequently, with heat therapy, there will be a decrease in muscle stiffness and an overall feeling of relief.
