Design: In this double blind model, twenty-eight (28) subjects met at the Bowerman Sports Medicine Clinic on the campus of the University of Oregon and were grounded to the earth via contact with a grounded yoga mat or were sham-grounded. Ten yoga exercises were repeated five times over a one-hour period. Blood was taken pre and post exercise and analyzed for blood viscosity using a scanning capillary viscometer. Results: Subjects connected to the earth significantly reduced their post exercise systolic blood viscosity (p = 0.03) and diastolic blood viscosity (p = 0.03). Conclusion: Grounding has the ability to affect exercise induced inflammation, thereby reducing blood viscosity. 16. G. Chevalier. “The effect of grounding the human body on mood,” Psychological Reports, vol. 116, no. 2, pp. 534–542, 2015. Earthing (grounding) refers to bringing the body in contact with the Earth. Health benefits were previously reported, but no study exists about mood. This study was conducted to assess if Earthing improves mood. 40 adult participants were either grounded or sham-grounded (no grounding) for 1 hr. while relaxing in a comfortable recliner chair equipped with a conductive pillow, mat, and patches connecting them to the ground. This pilot project was double-blinded and the Brief Mood Introspection Scale (comprising 4 mood scales) was used. Pleasant and positive moods statistically signifi- cantly improved among grounded— but not sham-grounded—participants. It is concluded that the 1-hr. contact with the Earth improved mood more than expected by relaxation alone. More extensive studies are, therefore, warranted. 17. G. Chevalier, G. Melvin, T. Barsotti. “One-hour contact with the Earth’s surface (grounding) improves inflammation and blood flow—A randomized, double-blind, pilot study,” Health, vol. 7, pp. 1022-1059, 2015. 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 65
