Magnets have been used for their healing properties since ancient times, and now a new study has found that they can reduce swelling when applied immediately after an inflammatory injury.
In their initial study, researchers from the University of Virginia set out to investigate the effect of magnetic therapy on microcirculation, which is blood flow through tiny blood vessels.
They placed magnets of 70 milliTesla (mT) field strength, which is about 10 times the strength of the common refrigerator magnet, near rats’ blood vessels and found that they dilated constricted blood vessels, and constricted vessels that were dilated. The results suggested that the magnetic filed could relax blood vessels and increase blood flow.
