I have been sleeping on a grounding mat for about one year at the suggestion of my son. I have not had a cold or sickness during that time. Also I think my spider veins have improved somewhat.

However, I too have ear fullness, tinnitus and hearing loss which continue to get worse with time. I’m suffering from what I believe to be long Covid symptoms that the mat has not helped. My symptoms include ear issues, blurring vision and constipation. I’m still trying to find help for these problems.
I had also hoped the mat would help.
