2 HOURS OF GROUNDING IMPROVES BLOOD VISCOSITY The surface of red blood cells carries a negative electric charge that maintains spacing of the cells in the bloodstream. The stronger the negative charge the greater the potential of the cells to repel each other, and the better the viscosity (thinner!) of the blood, and the better the flow. This is referred to as the ‘Zeta potential’. In this short video clip, you see a demonstration of the effect of grounding on the zeta potential of red blood cel
