Not at all. Humans have walked barefoot on the Earth, and sat and slept on conductive skins since time immemorial, thus absorbing into their bodies the Earth’s natural electric energy. During the late 1880s, a back-to-Nature movement in Germany featured walking barefoot and sleeping on the Earth for which many positive health benefits were claimed. Modern research on Earthing (also called grounding) is much more recent. Ongoing research led to a demand for the development of conductive sheets, mats, bands, and patches for use indoors that are the equivalent of being barefoot outdoors.
