At first glance, this all seems rather hippy-ish. But there is huge evidence that having you feet in contact with the earth has heart protective benefits. Grounding produces proven effects on physiology and health. In a 2013 study "grounding increased the surface charge on red blood cells and reduced blood viscosity and clumping". Grounding appears to be one of the simplest and most profound interventions for helping reduce cardiovascular risk and cardiovascular events. Blood is a complex fluid containing a variety of cells, proteins, nutrients, and waste products, along with dozens of clotting factors. The mobility or zeta potential of red blood cells is a simple method for measuring blood viscosity. This is because blood viscosity is strongly influenced by the blood cells surface charge that drives them apart. Grounding also has a positive impact neutralising reactive oxygen species.
