A **grounding bed sheet**, often called an earthing sheet, is designed to connect the human body to the Earth’s natural electric charge while sleeping. These sheets are typically woven with conductive materials, such as **silver or carbon fibers**, and connect via a wire to the grounding port of a standard electrical outlet or an external grounding rod. The underlying concept is that direct contact with the sheet allows for the transfer of electrons, which proponents suggest may help neutralize free radicals, reduce inflammation, and improve sleep quality by aligning the body with the Earth’s surface potential.
