Bests & Worsts Reviews from Amazon

This mat works but if you have thyroid issues like I do, you may not want to sleep with this every night. Like I did. This mat should only be used 30 mins a day. But I wanted more out of it. Which caused me to develop an overactive thyroid. When I'm actually taking meds for hypothyroidism. So just be careful. My dr was baffled on how my levels decreased so rapidly when on meds it takes a month or 2. So my meds were recently adjusted due to this. No I'm not on any new meds that could cause this, no I don't do drugs and my routine has not changed. Only addition was sleeping on grounding mat nightly for 3 weeks. So I researched and found a study that indicates the thyroid gland having significant reduction in TSH and T3 when using grounding overnight. It also decreases blood pressure and blood glucose. Cause I also suffer from high blood pressure. Without my meds I'm 140/90 ,On my meds I'm 126/73 but when I was sleeping on this mat, I seen numbers 123/51, 98/55, 100/60. So yes dont ground during sleep, if u do ,dont do it every night
