Grounding the Human Body Improves Facial Blood Flow Regulation: Results of a Randomized, Placebo Controlled Pilot Study
Earthing (grounding) refers to bringing the human body in direct contact with the negative electric charge of the earth’s surface by barefoot exposure outdoors or using special conductive indoor systems that are connected to the Earth. To determine if earthing improves facial blood circulation/flow, a double-blind study was designed with forty subjects either grounded or sham-grounded (27 grounded subjects and 13 sham-grounded subjects acting as controls) for at least one hour in a comfortable recliner chair equipped with conductive mat, pillow, and patches. The grounding systems were either grounded or sham-grounded via a wire to the ground port (third hole) of a power outlet. A Laser Speckle Contrast Imaging camera was used to continuously record changes in facial blood flow non-invasively. Facial blood flow regulation clearly improved among grounded— but not sham-grounded—subjects. The results demonstrate, for the first time, that even one-hour contact with the earth restores blood flow regulation to the face suggesting enhanced skin tissue repair and improved facial appearance with possible implications for overall health. Further studies, using larger comparison groups, longer monitoring times, and more measuring methods, are warranted in order to confirm the novel influence of the Earth as a protector of skin health and appearance.
Another case study was done in 2013:
Earthing (Grounding) the Human Body Reduces Blood Viscosity—a Major Factor in Cardiovascular Disease
Chevalier G, Sinatra ST, Oschman JL, Delany RM. Earthing (grounding) the human body reduces blood viscosity—a major factor in cardiovascular disease. Journal of Alternative and Complementary Medicine, 2013; 19(2): 102-110.
This experiment tested the effects of two hours of grounding on red blood cells (RBCs). Ten healthy subjects—seated in comfortable reclining chairs in a dimly lit, soundproof room—were grounded with conductive patches on their hands and feet, which were wired into stainless steel rods embedded in the earth outside. Blood samples from the subjects were analyzed under a microscope to determine zeta potential (degree of negative charge on the surface of a red blood cell) and RBC aggregation (clumping) before and after grounding.
For each subject, eighteen total measurements were tracked over the course of the two hour grounding period. Graphical data of these measurements revealed a significant increase in zeta potential and reduced RBC aggregation—meaning an increase in RBC mobility and storage capacity and a lower likelihood of clumping and clogging.
Results suggest that grounding reduces blood viscosity and inflammation, which are both vital for the prevention of cardiovascular disease. Conductive contact with the earth keeps the blood flowing efficiently, increasing its ability to deliver fresh oxygen and nutrients throughout the body.
