Mercola.com Dr. Pollack also offers some fascinating insights into the technique of earthing, or grounding—the simple act of walking barefoot to “ground” with the Earth. The scientific theory behind the health benefits seen from this simple practice is that your body absorbs negative electrons from the Earth through the soles of your feet.
Interestingly, Pollack adds support to this idea by explaining how the Earth is negatively charged, so when you ground, you’re connecting your body to a negatively charged supply of energy. And since the Earth has a greater negative charge than your body, you end up absorbing electrons from it.
These negatively charged electrons may then help increase the structure of the water in your cells—just as water increases in structure when a negative charge is introduced with an electrode.
