'Have you ever noticed how good it feels to walk barefoot on a sandy beach, or in a forest? There is a reason for that—it’s called the grounding effect. The reason for this sense of well-being is due to the fact that you’re receiving a surge of potent healing electrons from the ground.
The earth has a slightly negative charge, so when you stand barefoot on that sand, electrons from the earth flow into your body, giving you a virtual “transfusion” of healing power.
The featured documentary, The Grounded 2, is a sequel to the film The Grounded, released in 2013. The sequel features Step Sinatra, the son of cardiologist Stephen Sinatra MD, astronaut Dr. Edgar Mitchell, and yours truly, among many others.'
