Western scientists have also mapped out and proven the existence of this system of body points by using sensitive electrical devices. Stimulating these points with pressure, needles, or heat triggers the release of endorphins , which are the neurochemicals that relieve pain. As a result, 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. Besides relieving pain, acupressure can help rebalance the body by dissolving tensions and stresses that keep it from functioning smoothly and that inhibit the immune system.
Acupressure enables the body to adapt to environmental changes and resist illness.
Tension tends to concentrate around acupressure points. When a muscle is chronically tense or in spasm, the muscle fibers contract due to the secretion of lactic acid caused by fatigue, trauma, stress, chemical imbalances, or poor circulation. For instance, when you are under a great deal of stress you may find you have difficulty breathing. Certain acupressure points relieve chest tension and enable you to breathe deeply. As a point is pressed, the muscle tension yields to the finger pressure, enabling the fibers to elongate and relax, blood to flow freely, and toxins to be released and eliminated.
