Grounding overnight: what the research actually says.
Eight hours of skin contact with the Earth's potential — and the small studies that suggest it matters.
Grounding — sometimes called earthing — is the practice of restoring direct electrical contact between the body and the surface of the Earth. In the modern home, insulated by rubber soles and elevated floors, that contact has largely been lost.
The research base is small but interesting. Controlled studies have measured reductions in inflammatory markers, changes in cortisol rhythm, and improvements in reported sleep quality after nights spent sleeping on conductive sheets connected to a grounded outlet.
It is not a cure for anything. It is, at most, a subtle recalibration — a way of restoring a baseline that most of us live without.
The appeal is quieter than that: eight hours in gentle contact with the Earth's potential. A return to a condition our physiology assumes.
