Barefoot on Concrete, not Grounded.
We are an electrical energy source and when we are not grounded to the Earth, our body builds up electrical energy and stores it. The electrical energy changes the pH level in our body and begins to cause our blood cells to stick together, clump, restricting flow, thickening the blood, rather than repel each other so they can flow correctly, reducing the surface area of our cells needed for transfer of nutrients and waste removal. Grounding has instant positive effects on the human body.
