Pulsed electromagnetic field therapy (PEMF) is a whole body energy recharger. The body has natural ways of healing itself and pulsed electromagnetic fields play a major role in that process. The earth has a natural pulsed electromagnetic field but because of cellphones, powerlines, TVs, computers, microwaves, WIFI, Bluetooth, and other unhealthy electro smog devices we don't receive enough of the earth's naturals pulsed electromagnetic field.
