Deep Heat Patch delivers up to eight hours of deep relieving warmth directly on the site of muscular aches and pains, joint stiffness, backache, strains, sprains and menstrual cramps.
Heat increases the blood circulation in the skin and deeper tissues
When muscle spasm or tension is caused by local lack of oxygen - for example, after exercise, the increase in local blood flow induced by heat can reduce the feeling of pain by bringing more oxygen to the area.
Pain-sensing nerves are stimulated by natural body chemicals, serving as a warning of damage to tissue - an increase in local blood flow removes these chemicals, so reducing pain.
Heat also increases the ability of collagen, tendons and ligaments to extend, so gentle movement of affected areas is less painful.
