EMF stands for electro-magnetic frequencies. We are electric beings in an electric universe made of EMFs.
EMFs can be natural like the sun's radiation, lightning, or the Earth's frequency called the Schumann Resonance.
They can also be man-made, like the energy emitted from our cell phones, wifi, tablets, cell towers, Bluetooth, and other SMART devices.
Man-made EMFs include radiofrequency (RF) from wireless devices like cell phones and cell towers. Electricity is another type of EMF which includes dirty electricity. Finally, magnetic fields can either be given off by the Earth naturally or are created as electricity passes through electric system of your home for example.
