The north pole magnets are also ideal for use to correct spine injuries or help relieve back pains, headaches and even joint pains. For tissue healing like burns, the north pole magnet has proven to be effective as well. However, you should avoid using north pole magnets on pregnant women and to treat muscle weakness. Short history There may have been a revival of sorts regarding the role of magnets in a person s health and well-being, but this association goes a long way into the past. For over 2,000 years, magnet therapy in China had occupied a central role in Chinese medicine. It had also been mentioned in the earliest writings in Egypt, India and Greece. Among the well known methods include the use of magnetic mattresses, magnetic insoles and the more popular magnetic jewelry which uses bracelets, necklaces, earrings and rings as holders for the magnets. However, some would argue that magnetic jewelries do not induce much healing because of the small magnets used and the limited positions they are placed on the body. Historical records from Egpyt, India and Greece also showed the use of magnets in healing. Although used in alternative healing, it was until 1600s when a Swish physician Paracelsus acknowledged the used of his magnets for therapy. It was followed by another doctor named Dr. William Gilbert who studied the use of electricity and magnetism. By applying magnets on the surface of the affected area, the magnetic field relaxes the capillary walls of the body s cells resulting to increase blood flow to that part of the body and at the same time prevents the flow of liquids outside the cells which help control the pain. Some also claims that the same magnetic field disrupts muscle contractions preventing muscle spasms to occur. Bipolar magnets On the other hand, the bipolar magnets are considered more effective in stimulating surface tissues. The two-pole configuration is deemed better to treat injuries like wrist sprains. Additionally, some practitioners believe that the north side of the magnet calms a person while the south end stimulates.
