A growing body of evidence suggests that “earthing” – electrical connectedness to Earth, a.k.a. “grounding” affects human health. The recent book Earthing by Ober, Sinatra, and Zucker, as well as Nobel Prize winner James Oschman’s interest in the topic and sponsorship of Ober’s work brings attention to this matter.
To gain some understanding of the quantitative affects of grounding on health, M.D.s Karol and Pawel Sokal of the Military Clinical Hospital, Bydgoszcz, Poland conducted five different experiments wherein blood chemistry was assessed before and after subjects were electrically connected to Earth.

Their experiments included these five blood assays:
- serum calcium phosphate homeostasis and iron concentration
- electrolyte concentration
- thyroid hormone levels
- glucose concentration
- immune response to typhoid and tetanus injection
The basic earthing method involved electrically connecting the human subject to a copper plate measuring 60mm x 250mm placed upon damp ground. A copper wire ran from this plate to a second plate secured to the lower part of each subject’s leg, the goal being emulation of the electrical connectedness of a bare human foot being placed firmly on the ground as might be so in a culture or circumstance where one is barefoot.
The rationale for their interest – as expressed, and that of Ober and Oschman, is whether our modern existence is resulting in malady and disease as a consequence of electrical insulation from Earth – Earth being “the reference ground” for the global electrical system and in theory “all life” – the latter being the question of interest. The potential problem arises due to our electrical “isolation” from Earth, i.e. we tend not to go barefoot, we tend not to sleep in contact with Earth, our homes and offices tend to be electrically insulated from Earth, etc.
The results of their study are quite striking…They find that across all 5 areas, statistically significant changes in blood chemistry occur when the human organism is grounded vs. when it’s not. Grounding yielded:
- Decreased serum concentration of iron, calcium, and phosphorus in combination with reduced excretion of calcium and phosphorus – this suggesting storage of these minerals by the body. (The authors point out that the physiological affects of grounding are opposite those of weightlessness.) Even a 1 hour contact with Earth resulted in lowering of calcium and phosphorus concentrations. Alternatively, a 1 hour break with Earth following the period of overnight rest while grounded caused calcium and phosphorus levels to rise.
- Changes in thyroid hormone levels, thereby demonstrating grounding’s influence on metabolic action.
- A decrease in blood glucose in subjects with diabetes.
- Following typhoid and tetanus injection, grounding yielded a decrease in sodium, potassium, magnesium, iron, total protein, and albumin concentrations and an increase in transferrin, ferritin, and specific globulins, indicating heightened immune response, thereby demonstrating that immune function can be potentiated via grounding. Like electrolyte levels, changes in all of these factors reversed when contact with ground was interrupted for 1 hour.
The authors emphasize that grounding results in calcium-phosphate homeostasis that is opposite that of weightlessness, where it is known that astronauts lose bone mass rapidly during space flight. The current understanding of this phenomenon is that it is the loss of gravity and weight bearing that interrupts normal bone maintenance. The Sokal’s postulate that the loss of Earth’s electrical influence on the body may be an important mediating factor.
