The size of the magnet is essential because you want something that is not that noticeable and can be worn comfortably on a daily basis. Using magnets that are more than 1/8" thick is already quite a bother to wear. As a general rule, the more magnets used the stronger the effect and the better the results. When looking for the proper magnets, it is absolutely necessary to consider only high quality grades available in the market. Using magnets that are too small, too thin or just too low quality would result only to wasted time and efforts. Another important aspect of using magnets in therapies is the difference between unipolar and bipolar magnets. To date, these ailments include arthritis, Fibromyalgia, carpal tunnel syndrome, back pains, sciatica and general muscle aches and pains. Other diseases that magnet therapy is also known to give relief are diabetes, high blood pressure, high cholesterol, and hardened arteries. It also promotes sound sleep, calms the nerves, and assists the relief of drug addiction. Today, the use of magnets to treat illnesses has been discouraged pending further testing of the efficacy of magnets. Medical authorities have been reluctant to issue their approval on the use of magnets simply because they have not been formally tested. Types If you really decide to use magnet therapy, you have to choose first the many different types of magnets and magnetic devices available today. Theories Magnet therapy is almost similar to the theory of acupuncture. The north-seeking pole of magnets is placed on the afflicted areas. These are the specific points on the meridian channels of energy. The idea is to improve energy and blood flow. The main difference is that magnet therapy is non-invasive and dos not cause additional pain. Pain relief Researchers at Baylor College of Medicine in Houston found magnets effective at blocking pains caused by post-polio syndrome. The syndrome is marked by leg pains and affects up to 20% of polio patients later in life. In the study, 76% of the patients who were treated with a magnet had pain relief.
