Grounding

I had no sooner written about Japanese forest bathing than I read about "grounding," which is ... walking outside barefoot. Grounding, also known as "earthing," is a way of touching base with the essentials. Those who favor it say that it might help prevent chronic diseases, and research shows that it can improve sleep and lower stress.

Sounds touchy-feely (in more ways than one!) ... and yet, consider this: One theory that explains the positive effect of grounding is that earth's negative charge neutralizes the free radicals that can damage our cells. Antioxidants not from fruits and vegetables but from the earth itself.

And then there is the circadian rhythm aspect of grounding, the fact that touching ground can help regulate our autonomic nervous system, our breathing out and our breathing in.

The article in the Washington Post explaining this research ended with suggestions: Walk barefoot on ground or sand (something I'll be doing in a few minutes, as a matter of fact!). Garden in the earth, or even lean against a tree trunk.

We are only beginning to understand how connected we are to the natural world around us.
