HHS-OASH-2026-0397-2810 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2810 Experienced both headaches and ear ringing when holding the cell phone close to my ear, which subsides when cell phone is put on a surface and speaker phone is used. Also, when sleeping in a place where the router is on, sleep is very poor. In a place where the router is turned off, sleep is dramatically improved. When stayed in a building next to a cell tower, child had severe nosebleeds daily that subsided when away from the cell tower.
