From her explanation, The whole mechanism is based on discharging an unhealthy body, no matter it is positively or negatively (electrostatic) charged, to zero volt or charge. Embracing a tree is also the work of discharging of arms and palms to zero charge. Pavement Bricks and living trees contain moisture inside to increase the conductivity to the soil of mother earth. The remaining question is whether a neutrally, positively or negatively (electrostatic) charged body is more healthy. What the health \ hell level will one be at after practicing earthing for the second half of one's life??
@@oliviang7643 wet grounds facilitate good grounding so cement pavements \ bricks are all right if the moisture is high enough (like the mornings in nearly all the 4 seasons) to provide conduction to the soil underneath. Asphalt road is no good as it is a good insulator to block the conduction \ discharging with mother earth.
