I was interested in your reference to Dr. Christopher's work and being barefoot. I co-authored the Earthing book and am interested in finding any historical references to the health benefits of being barefoot outside.
Ray's experience of calmness and clarity by being outside in his socks was totally in sync with feedback that we get on a daily basis.
The fact is that Mother Earth is a treatment table!!! Just connect by being barefoot outside (or even in socks) or using one of the indoor Earthing systems while you sleep or work, and you get wonderful health benefits. This is as natural as it gets.
I welcome your response at info@earthinginstitute.net
