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] Studies assert that earthing increases the charge on red blood cells to reduce blood viscosity.[4] Additional claimed health benefits include 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] Objective evaluations of the degree of current exchange between the earth and a grounded human body have been found to be small, on the scale of nanoamperes, and do 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]
