I went to that first link and then in the second post it lead to a youtube.
I watched that youtube and got reinterested in purchasing the earthing pads. Then when I read one of the comments, I became fearful again of wasting money. I am very EMF sensitive. This is what the person commented:
"I have a grounding mat and a rod with a chord running outside and started feeling very buzzed and often got flu-like symptoms afterwards. I am EMF sensitive so I bought a Trimeter to measure the EMF's on the grounding mat. The grounding mat EMF's were in the hazardous area so I stopped using it and stopped recommending it. An electrician said this could be due to induction from electrical fields. Wrote to earthing.com—they knew nothing about the Trimeter measurements. I'd like an explanation.
