When heat is applied to your skin, it actually reduces the sensation of pain. Heat stimulates thermo receptors, which block your body’s pain transmitters from sending pain signals to your brain
Heat increases circulation to the injured or sore area, which means more oxygen and nutrients are sent to the damaged tissue
Heat helps stretch soft tissues and relax sore muscles which promotes flexibility and decreases stiffness
The application of ice is common for the treatment of most medical conditions that affect the musculoskeletal system.
Ice, when applied correctly, can be of enormous benefit to reduce pain, inflammation, and swelling. Most physicians agree that for an acute injury, ice is the cornerstone of treatment, as well as rest, compression, and elevation of the affected body part.
