The grounding effect can be measured with a multimeter device, which allows one to measure voltage in the body before and after grounding.
The video below shows how touching the Earthing sheet causes a significant drop in body voltage.
Why is body voltage important?
When not grounded, you will generally see a high amount of volts being carried by the body and this is often further increased when there is a presence of dirty electricity in the surrounding environment. Body voltage becomes even higher as we move further away from the ground. In fact, for every meter (3.28 feet) you are above the ground, 300 volts of charge will build up in the body. This means if you are in a second story bedroom, your charge would be 1,000 volts, on average.
As we know, carrying excess positive charge in the body can be a problem and is an important marker of inflammation. It is recommended that one adopts strategies such as grounding to combat any excess positive charge in the body and to stay in good health. When grounded, the body shares the same electrical potential as the Earth and this provides a protective effect against any excess positive charge.
