Most of us, however, could not explain the physical and physiological mechanisms causing the relaxation and pleasure. Most of us probably suspect it has something to do with the pleasure of being touched by another person and with the physical movement of muscles and other body parts. Massage therapists claim to understand the metaphysical reasons for the uplifting and relaxing effect of massage. Their explanations vary. Reflexology works by allegedly unblocking the 7,200 nerve endings in each foot so that they can respond to all of the glands, organs and other parts of the body and improve the blood supply as well.
Polarity therapy is a kind of acupuncture without the needles.
In acupuncture the metaphysical energy that gets blocked is known as chi. Over a period of time, people end up learning more about structure and how it works. Personally, I would prefer palpation. Massage therapists who are certified by the National Certification Board for Therapeutic Massage and Bodywork must take 500 hours of education classes and pass an examination. They must know some basic anatomy and physiology, as well as some first-aid.
