what is earthing

The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipments are grounded then if the insulation inside the equipments fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is effectively shorted and fuse will immediately blow. When the fuse is blown then the dangerous voltages are away.

Studies now show that just standing on the earth barefoot has amazing health benefits as we drain off free-radicals and the electric charge we carry with us. This phenomena is also known as "earthing".

Think of it this way. The earth is a giant car battery with a liquid metal core. It carries a strongly negative charge. And anything above the ground (such as in the air or insulated from the ground) carries a positive charge. This is why lightning strikes oocur, and why we need to “ground” or protect all of our electrical and electronic equipment, to keep them from sparking or short circuiting.

In essence, to ground something is to plug it back in to the earth, which is actually the third prong on our electrical outlets (called a ground).

Human beings, and all organisms for that matter, are electrical in nature as well. We get ekgs, mri’s, and all sorts of electrical tests to measure our health, hearts, and bodies; our nervous system works on electrical impulses, and even the heart beats with an electrical charge (which is why you may get a pacemaker if it starts getting out of tune).

We are electrical in nature, and like electrical equipment and electronics needs to be properly grounded to function well (if you’ve ever listened to an ungrounded radio you know what I mean, you’ll hear tons of static and background noise until it’s grounded), we need to be grounded for proper health and well-being and for proper functioning of our bodies.
