Ways Magnets are Used
Magnetic therapy has been used to treat everything from arthritis and fibromyalgia to migraines and insomnia. Most drug stores now carry wrist braces and back braces with magnetic inserts. There are even magnetic mattresses that are advertised to ensure a better night's sleep. While most still consider magnetic therapy in the alternative medicine field, there have been dozens of scientific studies that indicate magnets may provide an effective treatment for a variety of medical conditions. In a double-blind study by Dr. Carlos Vallbona, published in Archives of Physical Medicine and Rehabilitation, participants who used active magnets reported a significant reduction in pain when compared to a placebo group.
Theories
Magnetic therapy is not new, but dates back to ancient China, India and Egypt. Today it is even prescribed by doctors in many countries throughout Europe. One theory on how magnetic therapy works was that the magnets have an effect on the electromagnetic fields of the body. It is now known that the human body has not only biological reactions, but electromagnetic interactions. Many chemicals (ions) in the body have either a positive or negative charge. These ions are affected by magnetic fields. Typically the body balances the positive ions, such as sodium and potassium, and the negative ions like calcium and chloride. When there is an imbalance an increase in positive ions can trigger pain in the body. The theory behind magnet therapy is that the magnets can help restore balance and facilitate healing.
The Science of Magnetic Therapy
Therapeutic magnets or active magnets are not the same ones used on the refrigerator. They are much more powerful. The Magnetic Therapy Council explains that these magnets are composed of metal alloys such as iron, nickel or cobalt. When placed on the skin the magnet fields attract the iron in the blood and increase circulation to that area of the body. The increased blood flow brings oxygen and nourishment to the area and stimulates healing. In a study published in the Journal of Alternative and Complementary Medicine, Dr. Sala Horowitz points out that magnetic therapy has been approved for use with arthritis, non-healing bone fractures, female incontinence, inflammation and sleep management.
Misconceptions and Precautions
It is a myth that therapeutic magnets will draw the iron from the blood. The iron in the human body is chemically bonded in the hemoglobin. Using magnets will not cause anemia. However, as with any alternative treatment, individuals should exercise caution. Complementary medicine should be used in conjunction with, not in place of, conventional medical care. Never discontinue prescription medication or treatments without first consulting your physician.
