Grounding Shields You From EMFs

Untitled Design 1

We live in an electrified world surrounded by gadgets, appliances and wiring that constantly exposes us to electromagnetic fields (EMFs). With plenty of people becoming more and more sensitive to EMFs and suffering the health consequences of them, many people look for ways to reduce their exposure. One way to do that is earthing or grounding.

So how does being grounded help protect you from EMFs? Well, electrons are transferred from the Earth to the human body through physical connection to the Earth. We therefore equalise with the Earth’s electrical potential, giving us a net negative charge – just the way the body likes it!

But it’s not as simple as thinking the electrons from the ground are canceling out or neutralising the EMFs directly. The protective mechanism actually works through what is known as the “umbrella effect.”

Our bodies are conductors. To understand the umbrella effect, we first need to appreciate that our bodies are conductive due to the electrolytes and charged ions present, especially in our blood and cells. This allows alternating EMFs from sources like appliances and wiring to induce tiny currents and make our body’s electrons wiggle back and forth.

You can measure this effect by checking your body’s AC voltage with a multimeter – it will read higher when you are close to EMF sources compared to being further away. This increased “body voltage” happens because the EMFs are driving a movement of electrons inside you.

So when you become grounded or earthed, for example by going barefoot outside or using an earthing mat or bedsheet, your body’s electrical potential equalises with the electrical potential of the Earth itself (as I mentioned earlier).

By connecting your body to this vast electrical system of the Earth, your body essentially becomes an extension of it.

And this is where the protective “umbrella effect” comes into play. Once your body’s electrical potential matches the Earth’s, the EMFs experienced are deflected and pushed away from your body. It’s like opening up an umbrella – the umbrella doesn’t stop the rain, but it creates a deflected space around your body where the rain cannot enter.
