The Electric Earth “Earthing” is based on the idea that the ground is charged with negative electrical potential, and having skin contact with it helps charge your body with electrons. This is helpful to your body because your body functions on bioelectricity; your nervous system and your cardiovascular system are two prime examples of this. With a more balanced electrical charge, your body’s essential systems can perform better. For example, if your immune and healing systems had a better charge, you can be more resistant to diseases and recuperate faster. Many researchers attribute the strength and hardiness of people from times past to their contact with the Earth; their walking barefoot and sleeping on the ground enabled them to regularly recharge their body’s electrical load.
