Grounding, also called earthing, is a technique some people use to connect their physical bodies to the earth's electrical energy.  Planet Earth has a negative electric charge. Some scientists theorize that there is a transfer of free electrons to the human body during grounding.  This electrical conduction may lead to various physical effects, including pain reduction, changes in immune response, wound healing, effects on inflammation, and possible prevention and treatment of autoimmune diseases and chronic inflammatory conditions. The effects of grounding (Earthing) on inflammation, the immune response, wound healing, and prevention and treatment of chronic inflammatory and autoimmune diseases.
