HHS-OASH-2026-0397-1123 https://www.regulations.gov/comment/HHS-OASH-2026-0397-1123 2 decades ago I developed serious sleep problems. For 2 years I slept very little. Then one day I noticed a strange small structure on the roof of tthe neighbouring apartment block. I found out it had been installed there for 2 yrears. It was a cell phone booster station. I researched that and found out that it was likely the cause of my sleep problem. I coated our bed room walls facing it with 3 layers of tin foil and slept fine after that.
