Earthing is a totally new word to me, and I bet, to most of you as well. When I first came across an article about it recently, I was so intrigued that I read it to the last word.
No regrets, however. It's an interesting addition to the vocabulary, as well as to general knowledge.
Dr. Stephen Sinatra, a cardiologist, explains that Earthing, also known as grounding, is a caveman medicine. It means literally walking barefoot on the earth, sand, or grass. Concrete and slate surfaces would be alright, but not asphalt. Ceramic tile surfaces are also okay as long as the tiles are laid on top of concrete or gravel foundations.
