A grounding sheet, also called an earthing sheet, is a specially made bed sheet woven with conductive fibers (often silver or carbon) that connects your body to the Earth’s natural electrical field while you sleep. This connection is typically made by plugging the sheet’s grounding cord into a wall outlet’s ground port or into a grounding rod placed outdoors, which allows electrical charge from the Earth to flow into the sheet and, in theory, into your body.
Proponents of grounding sheets suggest that mimicking the experience of walking barefoot outdoors can enhance relaxation, support deeper sleep, and help balance the body’s electrical environment. Grounding sheets are one of many products that can be used for connecting to the Earth’s electrical charge. There are also grounding mats, grounding shoes, and grounding socks.
