The Research Behind Grounding

Big Pharma won't tell you about this — but peer-reviewed journals already have. Here's every published study on earthing and grounding, from 2000 to today.

25+ Years of Research

Research into grounding began in the 1990s with Drs. Karol and Pawel Sokal in Poland and Clint Ober in the United States. Since then, studies have documented measurable shifts in the body's electrical state, blood electrodynamics, and self-healing mechanisms.

The mechanism is straightforward: grounding transfers free electrons from the Earth into the body. These electrons neutralize free radicals — the same process that makes antioxidants effective. Across published studies and thousands of real-world reports, the pattern is consistent: reduced pain, lower inflammation markers, and improved recovery.
