Background: Research conducted during the last 15 y has demonstrated that grounding (Earthing) the human body to Earth's surface charge generates multiple beneficial physiological effects. Anecdotal reports include lowering of high blood pressure (BP).
Objective: To test such reports, a pilot case history series was undertaken with hypertensive patients in a single physician cardiology practice.
Intervention: Patients grounded themselves at home for at least 10 h/d for several mo.
Outcome measure: BP was measured at baseline in the clinic, and then, after starting grounding, 3 subsequent times in the clinic again at approximately monthly intervals. Patients were also given a BP monitor and were asked to measure their BP on Mondays, Thursdays, and Saturdays at 8:00 AM and 8:00 PM for 12 wk.
Results: All 10 patient measurements were found to be significantly improved at the end of the trial period, and some, well before the end. Systolic levels decreased during this time, ranging individually from 8.6% to 22.7%, with an average decrease of 14.3%.
Conclusion: This is the first known study measuring the influence of grounding the body on hypertension. The results indicate that grounding appears to be a safe BP-reducing therapy warranting further research.
