After 3-4 months with the earthing sheets - I suddenly realised I can get out of bed and walk normally with no pain. For several years I was bent over double with pain and stiffness until I had warmed up. Then it hit me I had not had any carpal tunnel problems for a few months either. This had been very severe and I was holding off going for surgery. Best of all, my 3-month average blood sugar test, (HbA1c) came in at 5.4 with no explainable reason. It had been over 7 previously. My diet & exercise regimen had not changed a bit. Then I realised another very painful experience had also been eliminated - constant static electricity. I would still get "shocked" opening the car door using gloves and taking off a dressing gown - thousands of flashes of light surrounding me. All gone. Nothing has changed except for using earthing sheets and mats for typing at the computer. Earthing makes so much sense when you understand free radicals, electrons and physiology.
