Refelexology is a system of massage used to relieve tension and treat illness, based on the theory that there are reflex points on the feet, hands, and head linked to every part of the body. It is considered a microsystem of acupuncture. Many explain reflexology through holographic theory. Holographic theory suggests all sub-areas of the body (feet, hands, ears, face) can be used to effect any area of the entire body just as DNA contains all the information to make the entire body and is contained in each cell of the body. Many find reflexology sessions to be extremely relaxing and often find relief in many of their chronic disorders as a result.
