The earth has its own electromagnetic field, aligned to the poles, and the cells of the human body also have subtle magnetic forces. Conventional medicine uses electromagnetic energy in imaging equipment, harnessing this force for diagnosis, and also in order to influence the body’s own electrical currents to promote healing, particularly of fractures. Complementary therapists claim that ordinary magnets can also do this, and many are beginning to use magnets as part of a healing programme.

The body has many electromagnetic energies travelling through it which are measurable or assumed, as in Eastern meridian channels, and magnetic therapy is particularly well known in Japan. The use of powerful magnets placed close to the body for a short or long period of time can influence blood flow, improving the oxygen supply to the area being treated, and stimulating the metabolism and speeding the elimination of waste products. Magnetic therapy may be used as a self-help treatment, and many magnetic products, such as shoe insoles, mattresses, pillows and car-seat covers are available. A practitioner will suggest the most suitable items for your needs, and show you how to use them. Special supermagnets may be used for specific points on the body, often over lymph nodes or acupuncture points.

At this time we still await some reasonable trials or studies of magnets being used in treatment. If a practitioner has had some experience or training then I can see no risk, except that I would avoid magnetic therapy in conditions that might have been triggered by electromagnetic energy, such as cancer.
