The PEMF Podcast 84. Is Grounding & PEMF The Same? 20 Year Grounding / Earthing Expert - Dr. Gaétan Chevalier
Mar 4, 2026
Dr. Gaétan Chevalier, physicist and director of the Earthing Institute, researches grounding and its effects on blood flow, inflammation and autonomic regulation. He explains what grounding is, how electrons move through the body, safe methods and testing, and how grounding compares and can work together with PEMF therapy. Practical tips and common myths are also addressed.

Episode notes
Physicist Turned Earthing Researcher Through Replication
- Gaétan moved from plasma physics and nuclear fusion research to studying meridians and earthing after meeting Dr. Motoyama and later Clint Ober, initially skeptical but convinced by replicated battery-powered studies.
- He recounts hands-on research where arthritis patients and massage therapists experienced measurable benefits, leading to continued earthing research.
Grounding Reduces Blood Viscosity Via Zeta Potential
- Grounding increases negative charge on red blood cells raising zeta potential, causing cells to repel and blood to flow more like wine than ketchup.
- Chevalier links this rheological change to easier cardiac workload and improved circulation measured in his studies.
Ground For At Least Thirty Minutes
- Aim for at least 30 minutes of grounding to produce measurable physiological changes like reduced local inflammation and changes in heart rate variability.
- Chevalier notes some healthy people respond in ~20 minutes, but 30 minutes is the reliable research-based threshold.
