How It Works

Direct skin contact with a conductive surface connected to Earth ground allows electron transfer from the Earth's negative potential to the body. Proponents theorize this neutralizes reactive oxygen species and reduces inflammation, though controlled human trials remain limited.

1

Electron Transfer

Conductive carbon mat connected to ground port of electrical outlet transfers free electrons from the Earth to your body.

2

Desk or Bed Use

Place under bare feet at standing desk or on mattress for passive grounding during work or 7–8 hours of sleep.

3

Safety Resistor

Built-in 100kΩ resistor limits current flow. Includes ground-only plug adapter that connects to earth ground, not neutral.
