Do Magnetic Bracelets Have Side Effects?

Magnetic bracelets used for magnet therapy may have some side effects that include dizziness, nausea, heavy menstrual periods or diarrhea, notes WebMD. While these are some side effects mentioned by people undergoing magnet therapy, there isn't enough evidence to suggest these side effects are directly related to the use of magnets or wearing a magnetic bracelet.

People with a defibrillator or pacemaker should use caution when wearing magnetic bracelets because magnets can interfere with the proper function of this technology. Overall, magnetic bracelets appear safe with little side effects and won't interfere with a pacemaker or defibrillator implant as long as the bracelet is kept at least 6 inches from it, states WebMD.
