PEMF stands for Pulsed Electro Magnetic Fields. A PEMF Therapy mat provides extremely low frequencies in a Pulsed form to penetrate every cell in the body and force them into Resonance with the Earth Based 0-30Hz frequency range and to charge your cellular batteries. Why is it important? We are meant to be in harmony with the Earth based frequencies range of 0-30 Hz. These were the only frequencies surrounding us before electricity was introduced and the only frequency range within which our cells can be fully energized and heal. Protect yourself against the ever present wireless and harmful electrical frequencies surrounding us.
