HHS-OASH-2026-0397-0037 https://www.regulations.gov/comment/HHS-OASH-2026-0397-0037 I am a 74-year-old female in excellent health and suffer from EMF/RF hypersensitivity. It started in Spring of 2023 when I upgraded to an iPhone 14. Upon using it, I experienced tachycardia, multiple arrythmias, light headedness, loss of energy and confusion. I stopped using my cell phone and began extensive research into the cause. With the help of a Building Biologist recommended by SafeTechNC.org, I was able to keep myself safely distanced from the wireless radiation from cell phones, routers, blue tooth devices, computers and cell towers. Meanwhile, I visited two cardiologists; one in Wilmington, NC and one at Duke University Hospital in Durham, NC. Both cardiologists said that my heart is healthy but reacting to outside stimuli. I told them about wireless radiation and my cardiac response to it. They could not confirm wireless radiation as the cause, because they had never heard of such a thing. So today, after countless attempts to build my resilience to wireless radiation, I continue to be sensitive but not hypersensitive. I am grateful for that. Susan Barrus
