Earthing therapy
Within the sphere of fringe science, earthing or grounding is a practice which proponents claim provide an array of health benefits.[1] The therapy involves being in direct physical contact with the ground or with a device connected to electrical ground.[2][3] A study conducted by Dr Stephen Sinatra, Gaétan Chevalier and James Oschman and published in the Journal of Alternative and Complementary Medicine claims that earthing increases the charge on red blood cells to reduce blood viscosity.[4] A further followup article by James Oschman and published in the same Journal claimed health benefits included normalization of cortisol and improved sleep.[5][6] However, the claims rely on poorly designed studies that lack sample sizes large enough to be significant.[7] An objective evaluation published in the Journal of Chiropractic Medicine of the degree of current exchange between the earth and a grounded human body was been found to be small, on the scale of nanoamperes, and did not appear to reflect information beyond subject motion.[3] Robert Lahita, a rheumatologist and microbiologist, calls the claims of health benefits "really wacky. I don't even hesitate to say that's really crazy."[8] Some of the proponents also appear to have a substantial commercial interest in the therapy.[9]
