Stimulating specific points on the body can trigger the release of endorphins (chemicals produced by the body that relieve pain). When endorphins are released, pain is blocked, and the flow of blood and oxygen to the affected area is increased. This causes the muscles to relax and promotes healing. In acupressure, as with most traditional medicine concepts, local symptoms are considered an expression of the whole bodys condition. When performed correctly, acupressure increases circulation, reduces tension and enables the body to relax. Reducing tension, in turn, strengthens the immune system and promotes wellness. However, applying acupressure too abruptly, or using too much force during treatment, can lead to bruising and discomfort. Great care should be used when applying pressure to points on or near the abdomen, groin, armpits or throat. Special care should be when treating pegnant women or those with recently-formed scars, burns, infections or skin lesions.
