  • Benefits of Heat Therapy Historically, heat has been a natural remedy used both to relieve pain and enhance the recovery process. By increasing the temperature of the skin surface and underlying tissues, heat stimulates the thermoreceptors- sensory receptors that respond to heat and cold - which then help block transmissions of pain signals to the brain. This translates into a significant decrease of discomfort. Heat therapy increases blood flow, which helps to decrease stiffness, relaxes sore muscles, and provides soothing comfort. Heat should not be used on areas of swelling and bruising. (If swelling occurs, use ice, then apply heat after the swelling goes away.) This was taken from www.thermacare.com
  • Muscular pain is caused by the tightening of the muscles. Heat makes objects expand. So applying heat to a painful, or tightened muscle, stops the tightening by expanding the muscle. Factoid#21 - Cold makes thing shrink.
