How Do Magnetic Wrist Bands Work?

History and Theory

Ever since ancient Egypt, physicians have speculated on the potentially beneficial effects that magnets might have on the body. Magnetic fields can change the way that electricity works, and as we now know, the human body runs on a significant amount of electricity. The basic theory behind magnetic wrist bands, and magnet therapy in general, is that the magnetic fields generated by wearing the band will affect the iron in the blood and the flow of electricity through the nerves. This is supposed to cause a number of positive effects in the wearer's body.

Effects

Some claim magnetic wrist bands can reduce pain and swelling related to a number of conditions, including carpal tunnel syndrome and arthritis. The magnetic fields are said increase the production of red blood cells, in addition to the oxygen-carrying capacity of the blood cells that already exist, according to magnetictherapybracelet.co.uk. Additionally, magnetic wrist bands claim to increase blood circulation, which is also beneficial. Blood that carries more oxygen and nutrients to the body's extremeties can help reduce pain and swelling in the wrists and fingers, which is where most wearers have pain they want relieved.

Evidence

Despite all of the claims as to what benefits magnetic wrist bands, and magnetic therapy in general, can provide, there is very little evidence that these wrist bands do more than lighten a person's wallet, according to mycarpaltunnel.com. If someone tries to dig past the basic theory of magnetic wrist bands, it begins to look less and less like hard science with definite results. However, there is also no evidence that wearing magnetic wrist bands is harmful in any way to the wearer. So if someone wants to try magnet therapy for their own aches and pains, there's no proof that it works, but also no proof that it hurts.
