For a few years, I'd been waking every 2 or so hours throughout the night - often laying in bed for an hour or more trying to get back to sleep. I thought it must have been a placebo effect after the first night of using the earthing sheet as I woke only once and fell easily back to sleep. The next night I slept straight through. Even after two weeks of sleep-filled nights, I was convinced it was a placebo effect. Into the third week, I PROVED to myself it WAS a placebo effect as I returned to my old waking every couple hours pattern ... until I arose in the morning to discover I had not switched on the socket. NOT PLACEBO. Thank you, Mother Earth!! Thank you Sleep Earthed!
