This article expounds on the concept of grounding. I hope you'll take a look. It's that important!

an excerpt:

Earthing Triggers Physiological Normalization
For me, the concept of reconnecting to the Earth has revealed one of Nature's great healing secrets. On a personal note, I experienced an immediate cessation of annoying restless legs syndrome when I started sleeping grounded two years ago. I sleep grounded now whether I am at home or traveling. Over time, the also annoying need to get up at night to pee, typical of men my age (72), has substantially abated. Some nights I get up once. Others not at all. A couple of my friends have had the same results.

My wife has less pain from substantial musculoskeletal issues as a result of sleeping grounded and using grounded EKG patches during the day. One woman who transcribes for me wanted a conductive bedsheet after hearing and transcribing some of the interviews of doctors and patients that I did for the book. After she started sleeping grounded, she told me that she was "absolutely amazed." Not a single flare-up of her fibromyalgia pain.

To quickly experience Earthing yourself, just walk or sit barefoot on grass, sand, gravel, or unpainted concrete ground surfaces that conduct energy. Wood, asphalt, and plastic do not conduct. Stay for at least a half hour or so and at the end of that time you will notice you are calmer, and if you had pain to begin with, it will be less, or maybe even gone.

Biophysicist James Oschman, PhD, a leading expert and author on energy medicine, sums up Earthing this way: "The moment your foot touches the Earth, or you connect to the Earth through a wire, your physiology changes. An immediate normalization begins. And an anti-inflammatory switch is turned on. People stay inflamed because they never connect with the Earth, the source of free electrons which can neutralize the free radicals in the body that cause disease and cellular destruction."

Please read the book to learn the full story, the research details, and the dramatic feedback from doctors and patients. There is much in the book that will interest sophisticated, open-minded practitioners and health-oriented readers of this publication. You will be amazed, as I was, by the primordial power and promise of this concept.

The Benefits of Earthing
For more than ten years, Earthing research and feedback from individuals who have grounded themselves, primarily while sleeping at night, demonstrate a multitude of benefits. Here is a short list of them:
improvement or elimination of the symptoms of many inflammation-related disorders
reduction or elimination of chronic pain
better sleep and faster to sleep
increased energy
lowered stress, more calmness by cooling down the nervous system and stress hormones
normalization of the bodys biological rhythms
thinner blood, improved blood pressure and flow
muscle tension and headache relief
lessened hormonal and menstrual symptoms
dramatically faster healing and reduction/prevention of bedsores
reduction/elimination of jet lag
protection against potentially health-disturbing environmental electromagnetic fields (EMFs)
accelerated recovery from intense athletic activity
