There is some confusion surrounding the topic of electromagnetic fields (EMFs) and Earthing. Some people are afraid that their Earthing sheet will attract EMF frequencies like an Antenna. However, this would be impossible because in order for an antenna to work, it cannot be grounded. Whenever you are grounded, your skin effectively produces a ‘faraday cage’ effect and will repel electromagnetic fields (EMFs) coming from the external environment. This effect can be demonstrated with a quick multimeter test measuring body voltage before and after touching the Earthed surface.
This is also known as the “umbrella effect”, discovered by Nobel Prize winner Richard Feynman. Feynman explains; when the body’s potential is the same as the Earth’s electric potential (and thus grounded), it becomes an extension of the Earth’s gigantic electric system. The Earth’s potential thus becomes the “working agent that cancels, reduces, or pushes away electric fields from the body.”
In addition, it is not possible for EMFs to be ‘pulled’ or ‘attracted’ as EMFs do not have electric charges. They cannot be attracted to anything. They simply radiate outward to infinity from an emitting source, such as electric wires, appliances, and phone masts.
