Shiatsu is a form of massage originating in Japan that uses finger and palm pressure on parts of the body called meridians. It is considered a holistic therapy that can help relax muscles and reduce stress and pain. While there is no evidence it can treat diseases, proponents believe it can aid conditions like arthritis, headaches, and issues related to pregnancy and circulation. The related technique of zen shiatsu incorporates elements of Buddhist meditation to enhance the massage and understand chi or life energy flow through the meridians.
