Magnetic Field Therapy - Topic Overview

What is magnetic field therapy?

Magnetic field therapy uses magnets to maintain health and treat illness.

The human body and the earth naturally produce electric and magnetic fields. Electromagnetic fields also can be technologically produced, such as radio and television waves. Practitioners of magnetic field therapy believe that interactions between the body, the earth, and other electromagnetic fields cause physical and emotional changes in humans. They also believe that the body's electromagnetic field must be in balance to maintain good health.

Is magnetic field therapy safe?

Young children and pregnant women should not use magnetic field therapy, because the safety of this therapy is not proved. People who have medical devices or implants with a magnetic field, such as a pacemaker, should not use magnet therapy, because it could interfere with the function of the implant.

Magnet therapy is not thought to have negative side effects or complications when it is combined with conventional medical treatment.

Always tell your doctor if you are using an alternative therapy or if you are thinking about combining an alternative therapy with your conventional medical treatment. It may not be safe to forgo your conventional medical treatment and rely only on an alternative therapy.
