Hi Olsen, do you still use the grounding sheet? I found this from Dr. Mercola's letter a few days ago - Grounding Helps Thin Dangerously Thick Blood and Fights Inflammation and Disease. It tells some science behind Grounding -

When you walk barefoot, free electrons are transferred from the earth into your body, and this grounding effect is one of the most potent antioxidants we know of.
Inflammation thrives when your blood is thick, and you have a lot of free radical stress, and a lot of positive charges in your body. Grounding effectively alleviates inflammation because it thins your blood and infuses you with negatively charged ions through the soles of your feet.
Surfaces that allow for proper grounding include sand, grass, bare dirt, and untreated concrete, brick and ceramic tile. Leather-soled shoes also allow you to ground while walking, whereas rubber-soled shoes disconnect you from the earth and block beneficial electron transfer.
Grounding helps thin your blood by improving its zeta potential, which means it improves the energy between your red blood cells. Research has demonstrated it takes about 80 minutes for the free electrons from the earth to reach your blood stream and transform your blood.
Grounding is contraindicated if you take Coumadin, as it may thin your blood too much.

Very interesting!
