One-Hour Contact with the Earth’s Surface (Grounding) Improves Inflammation and Blood Flow—A Randomized, Double-Blind, Pilot Study


Earthing (grounding) refers to the human body being in contact with the surface of the Earth by barefoot exposure outdoors or using special indoor systems connected to the Earth. Previous studies have showed multiple beneficial effects as a result of such contact, including better sleep, normalization of cortisol, reduced inflammation, pain and stress, and better blood flow. To determine if Earthing for one hour improves facial blood circulation, forty middle-aged volunteers were divided into a grounded group and a sham-grounded group according to a double-blind procedure. They were asked to sit in a comfortable recliner chair equipped with a grounding mat, pillow and patches. The grounding systems were either grounded or sham-grounded via a wire to the ground port of a power outlet. An infrared imaging camera was used to measure changes in blood flow and temperature. Thermal imaging showed clearly improved circulation of fluids (including blood) throughout the torso, which in turn, translates into enhanced delivery of blood to the head and improved blood circulation in the face as well. The results of this innovative study demonstrate that even one-hour contact with the Earth appears to promote significantly autonomic nervous system control of body fluids and peripheral blood flow that may improve blood circulation in the torso and face, facial tissue repair, skin health and vitality and optimize facial appearance (face anterior view p = 0.002; face lateral views p = 0.017; full anterior torso view p = 0.002). Further study using larger comparison groups and following subjects for a longer period of time (longitudinal study) is warranted.
