By Dr Mercola,
The terms “earthing” and “grounding” are interchangeable. It is simply the act of placing your bare feet on the earth, or walking barefoot. When you do, free electrons are transferred from the earth into your body, and this grounding effect is one of the most potent antioxidants we know of.
Unfortunately, few people ever walk barefoot anymore to experience it.
Hopefully, as more and more people become aware of the importance of being grounded, this will change, or at the very least spawn a much needed change in the way most footwear is made. Synthetic rubber soles disconnect you from the earth. Leather soles do not. So you can still find shoes that allow you to remain grounded without going barefoot.
Grounding has numerous benefits, aside from creating a general feeling of well-being. For example, walking barefoot can help ameliorate the constant assault of electromagnetic fields and other types of radiation from cell phones, computers and Wi-Fi.
By getting outside, barefoot, touching the earth, and allowing the excess charge in your body to discharge into the earth, you can alleviate some of the stress put on your system. That is the grounding effect. I have personally prioritized grounding myself to the earth as much as possible for over 5 years.
