Magnetic bracelets are commonly used to treat the symptoms of arthritic conditions. Copper is considered to have anti-inflammatory effects in the body, and may therefore have painkilling properties. One study showed that copper from a bracelet can be absorbed into the body, and it does seem that this can offer some relief from arthritic pain. There are countless reports of people who have found magnetic therapy has relieved a variety of conditions including arthritis, menstrual cramps, headaches and carpal tunnel syndrome. It is not known for sure how magnets work. What is known, however, is that magnetic fields exist in all living things, including our own bodies, and some scientists believe that an imbalance in the body's field can lead to pain and disease. It is thought that magnets may rebalance the body's energy, thereby restoring health and relieving pain. There is also some evidence that magnets may improve blood flow, helping with the delivery of oxygen and nutrients to the body's tissues.
