The main symptoms I experienced while being exposed to these technologies were difficulty concentrating and extreme headaches that only subsided after a nights sleep. Cell towers and groups of smart meters have proven to be the most dangerous sources that I have found. Wifi will also cause concentration issues that will increase with signal strength, and multipule range extenders. This became obvious during wifi rollouts into retirement homes where the units were installed one after another down all the hallways.","attachments":[],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-4691","tags":["health-experiences","sleep-cognition","exposure-places"],"source_hash":"143b359178ff3e248d07fc5a152fea35c33d6e5a80ad540068a1b484370e2db7","slug":"health-experiences-comment-4691","classification":{"id":"HHS-OASH-2026-0397-4691","body_sha256":"72fbc9dd0a7b500562baffb90f983b96f1593b742119b2858a1b5e82187c5854","status":"ai_reviewed","primary_topic":"occupational","topics":[{"id":"occupational","evidence":"As a worker with occupational exposure in the telecommunications industry"},{"id":"neurological","evidence":"difficulty concentrating and extreme headaches that only subsided after a nights sleep."},{"id":"smart-meters","evidence":"Cell towers and groups of smart meters have proven to be the most dangerous sources that I have found."},{"id":"wifi","evidence":"Wifi will also cause concentration issues"},{"id":"infrastructure","evidence":"Cell towers and groups of smart meters"}],"summary":"Reports occupational exposure in telecommunications associated with headaches and concentration difficulties that improved with distance or sleep.
