How Magnetic Therapy Works
|
All physical and mental functions are controlled by electromagnetic fields produced by the movement of electro-chemicals (ions) within the body. When an injury occurs and tissue is damaged, positively charged ions move to the affected area, causing pain and swelling. In order for healing to take place, the injured site must be restored to its natural negative electromagnetic charge. Pain and inflammatory-related electro-chemicals must be removed and oxygen and nutrients transferred to the area.
 The application of a magnetic field to an injured area helps restore the normal electromagnetic balance. The magnetic field relaxes capillary walls, as well as surrounding muscle and connective tissues, allowing for increased blood flow. More oxygen and nutrients are transferred to the injury site, while pain and inflammatory-related electro-chemicals are more efficiently removed. The overall process restores the normal electromagnetic balance of the area, relieving pain and inflammation, and promoting accelerated healing.
Several controlled clinical studies conducted in the past few years suggest that magnets may effectively treat some disorders. And a few health-care providers are routinely using magnets for a host of conditions.
Blechman, an associate professor in orthodontics at Columbia University's School of Dental and Oral Surgery, has used magnets for years with orthodontic patients to move teeth and to accelerate new bone growth. Some of his faculty colleagues at Columbia's medical school are using magnets experimentally to reduce pain among people who've had coronary artery bypass procedures, he said.
A small number of studies have found magnets, either "permanent" magnets or electromagnets, to be effective in relieving certain kinds of pain and hastening wound-healing. Perhaps most significantly, electromagnets are being used experimentally at several university medical schools to treat depression. The procedure is known as transcranial magnetic stimulation.
Individual response time will vary, and can range from a few minutes, to a few weeks. The effectiveness of magnetic therapy is dependent upon using the correct magnetic products, the length of time they are applied, and the type and severity of the problem.
