We live on a planet with a magnetic field and the surface of the earth is flowing with free electrons. You can picture it like a big battery- that gets charged up by solar radiation, lightning storms around the world, and the molten hot core in the center of the earth. Animals and creatures may somehow detect this electrical frequency/magnetic field and they can use this sense to help migrate or navigate. Humans are made of mostly salt water which is a good conductor and so we are affected by charges in the earth too.
The Earthing theory* is that once a person makes a conductive connection with the earth, that the free electrons not only instantly ground them, but the longer the connection, the more electrons accumulate in the body and it "recharges" you- so to speak....like a recharging battery! This gives us a whole new meaning to "recharging at the beach"!
We all hear that anti-oxidants are good...but what does that mean? Why are they good? So what is oxidation anyway? Heres an excerpt from Wiki on oxidation:
...and WIki on free radicals....
- Free Radicals: For most biological structures, free radical damage is closely associated with oxidative damage. Antioxidants are reducing agents, and limit oxidative damage to biological structures by passivating them from free radicals. Free radical reactions are redox reactions that occur as a part of homeostasis and killing microorganisms, where an electron detaches from a molecule and then reattaches almost instantaneously. Free radicals are a part of redox molecules and can become harmful to the human body if they do not reattach to the redox molecule or an antioxidant. Unsatisfied free radicals can spur the mutation of cells they encounter and are, thus, causes of cancer.
Part of the Earthing theory is also that the free electrons from the Earth are used in the body to prevent free radical damage. The negatively charged electron is attracted to a positively charged ion in the body to create an ionic pair. The electron would be satisfying the free radical. This would then neutralize the damage done in the body.
So even though there are types of oxidative damage that we don't want happening in our bodies, there is also good oxidation too- that comes in the form of breathing in oxygen. Let us not forget that we need oxygen to live! There are many good biochemical things that happen in our bodies when our cells are oxygenated. In fact many chemical pairs in the body are just waiting to be oxidized by an oxygen atom- which sometimes they have to wait too long! Cells need to metabolize and repair and they need oxygen to do it! Hydrogen needs oxygen to become water. These are good oxidation in the body. Toxins and pollutants mostly have positive charges- those are the oxidative bad guys that we need negative ions for. Besides the earth giving us electrons, there are also negatively charged/electron donor minerals that the body can use, yet many people seem to be deficient in: Magnesium, iron and zinc are a few. The body can use these elements to satisfy free radicals or positively charged particles.
....BACK TO LAYMAN'S TERMS....
Now you know how scientifically, getting grounded in nature can heal, calm and recharge our bodies!
So get your bare feet in the ground or swim in the ocean to re-charge your body and breathe some fresh air to oxygenate your cells!
