HHS-OASH-2026-0397-3719 https://www.regulations.gov/comment/HHS-OASH-2026-0397-3719 I am reporting significant physical and neurological symptoms that I associate with exposure to 5G and other electromagnetic fields (EMF's) I feel as though I can sense nearby cell towers before I actually see them. I experience what feels like electricity running through my body, severe headaches, nausea, and electrical sensations traveling down my arm and occurring in areas where I have metal hardware in my body. I also can experience difficulty concentrating, brain fog, and profound exhaustion that interfere with my abililty to function normally. These experiences are distressing and affect my overall quality of life. My medical history is complex and includes dysautonomia, MCAS, TBI, chronic inflammation and I do believe this has made it much worse, severe osteoporosis with multiple vertebral fractures, and persistently low iron stores. I have also experienced significant environmental sensitivities and have a history of mold exposure including stachybotrys. I am particularly concerned about the relationship between my environmental exposures, neurological symptoms, and overall health. Given my persistently low iron levels and exhaustion, I am concerned that environmental factors may be contributing to my declining health. I recognize that I cannot establish EMFs as the cause of my iron deficiency without scientific evidence, but I believe these concerns deserve further investigation. I urge HHS to support independent, rigorous research into radiofrequency radiation, 5G infrastructure, and other electromagnetic exposures. Research should examine neurological symptoms, headaches, nausea, sensory disturbances, concentration difficulties, fatigue, individual susceptibility, and potential effects in people with complex chronic illnesses. I also encourage researchers to investigate whether reported symptoms correlate with objectively measured exposure levels and whether there are identifiable biological mechanisms that could explain the experiences. My goal is to help advance research that provides clear answers about potential health effects and appropriate public health protections.
