James Oschman, PhD, is one of the most prolific, and most simple-to-understand scientists who writes about the scientific basis for energy (i.e. electro-magnetic) medicine. Oschman has written a number of books, and even more papers, but his paper called: Assume a Spherical Cow: The role of free or mobile electrons in bodywork, energetic and movement therapies, is a great introduction to the whole idea.
You can see the paper for yourself HERE (scroll down to the bottom of the page), and I highly recommend reading it if you’re at all interested in this subject, but here’s the main points:
To quote Oschman: “Virtually every modern disease, including the diseases usually tied to aging, have been linked with chronic inflammation.”
To put this into more plain English, earthing the body means that that there are more ‘free’ electrons available to bind to - and neutralize - the free radicals that can do so much harm to human health.
To find that out, you’ll have to read Oschman’s paper for yourself… But take heart, because it’s an easy read and well worth the effort.
