HHS-OASH-2026-0397-1268 https://www.regulations.gov/comment/HHS-OASH-2026-0397-1268 I am submitting this comment as an individual, based on my own recent experience. In the last two years I have developed what feels like a new sensitivity to certain wireless equipment. I had not had this problem with similar devices before. After I upgraded my home network to Wi-Fi 6 and plugged in the new router, I immediately developed a severe headache and nausea. Both stopped when I unplugged the router. I now keep it in a separate room. If I spend more than a few minutes in that room, the headache and nausea return. I have also had similar headaches, with a burning sensation, on recent flights. I believe this may be related to in-flight Wi-Fi. I now avoid Bluetooth headphones and generally keep my distance from this kind of equipment. I am not claiming this proves a specific medical mechanism. I am reporting a consistent pattern in my own life and urging HHS to support research into whether some people have become more sensitive to RF/EMF, including newer Wi-Fi generations and dense wireless environments (homes, aircraft). Distinguishing established evidence from emerging findings and uncertainty would help families and policymakers. Thank you for considering public input.
