It is not a secret that spending time in nature is good for you. For years, researchers have been detailing how people who live near green spaces — parks, greenbelts, tree-lined streets, rural landscapes — have better physical and mental health, and practices such as Japanese forest bathing and Nordic hygge, which has a strong outdoorsy component, are being embraced here in the United States. Could grounding be next?
I was intrigued when a colleague recently recommended a mutual patient — seeing her for stress management and me for nutritional advice — experiment with walking barefoot in the grass for a short time each day. A few weeks later, I stumbled across an article that gave a name to that practice — grounding. The idea behind grounding, also called earthing, is humans evolved in direct contact with the Earth’s subtle electric charge, but have lost that sustained connection thanks to inventions such as buildings, furniture and shoes with insulated synthetic soles.
Advocates of grounding say this disconnect might be contributing to the chronic diseases that are particularly prevalent in industrialized societies. There is actually some science behind this. Research has shown barefoot contact with the earth can produce nearly instant changes in a variety of physiological measures, helping improve sleep, reduce pain, decrease muscle tension and lower stress.
There are many reasons connecting with nature is good for mind and body, but electricity probably is not one you have considered. If you think back to the last time you took a science class, you may remember that everything, including humans, is made up of atoms. These microscopic particles contain equal numbers of negatively charged electrons, which come in pairs, and positively charged protons, so an atom is neutral — unless it loses an electron. When an atom has an unpaired electron, it becomes a “free radical” with a positive charge, capable of damaging our cells and contributing to chronic inflammation, cancer and other diseases. In this case, “positive” is not a good thing.
