Grounding / Earthing Research
Peer-reviewed research on electrical grounding of the human body, electron transfer, and physiological effects of earth contact.
Note: Grounding is an emerging research area with a smaller body of literature. Studies are primarily observational and mechanistic.
Proposed Mechanisms & Findings
Key findings from 300 studies on earthing and grounding.
Reduced Blood Viscosity
Grounding increases zeta potential of red blood cells, reducing blood viscosity and improving circulation. Effect measurable within 2 hours.
Decreased Inflammation
Studies show reduced inflammatory markers and faster wound healing. Free electrons from earth neutralize reactive oxygen species.
Improved Sleep Quality
Grounding normalizes cortisol rhythm, with participants reporting faster sleep onset, fewer night wakings, and feeling more rested.
Heart Rate Variability
Grounding increases parasympathetic nervous system activity, improving HRV within 40 minutes of contact with earth.
Pain Reduction
Delayed onset muscle soreness (DOMS) significantly reduced when grounded during recovery. White blood cell response normalized.
Electron Transfer
Earth maintains a negative electrical potential. Direct contact allows electron transfer, potentially balancing the body's electrical state.
The Grounding Hypothesis
Earth's Charge
Earth maintains a negative electrical potential of ~5 million volts between surface and ionosphere
Electron Flow
Direct contact allows free electrons to flow into the body, potentially neutralizing free radicals
Bioelectrical Reset
May normalize the body's electrical state, affecting inflammation and circadian rhythms
