Wi-Fi & indoor exposure

Public Comment on Electromagnetic Hypersensitivity Submitted to: U.S. Department of Health and Human Services Docket: HHS-OASH-2026-0397 I am submitting this comment as someone who has experienced significant symptoms that I associate with electromagnetic field (EMF) and radiofrequency (RF) exposure. I have a history of concussion, and my electromagnetic sensitivity began after my concussion in 2018. My symptoms include intense head pressure, heat and burning or tingling in my head and face, ear pressure, rapid heart rate, and chest fluttering. Symptoms have occurred in environments such as airports, train and bus stations, hybrid vehicles, and anywhere where wifi is present. Traveling on highways is difficult because cell towers create symptoms while in the car. I cannot have wifi or streaming in my home, and must drive a car without updated electronic/wireless systems. Symptoms can take three to four days to subside. These experiences have affected my daily life. I recognize that my experiences alone cannot establish causation. However, I believe that people experiencing these symptoms deserve compassionate medical evaluation and rigorous scientific investigation. I respectfully ask HHS to: Fund independent research into electromagnetic hypersensitivity, including possible neurological, autonomic, and other physiological mechanisms. Investigate whether people with a history of concussion or other neurological conditions may experience different symptom patterns upon exposure. Conduct a transparent review of the scientific evidence underlying current RF exposure standards, including uncertainties and potential health effects that remain insufficiently understood. Develop clinical guidance to help healthcare professionals evaluate and treat people reporting electromagnetic sensitivity without dismissing their symptoms or assuming an unproven cause. Include affected individuals in setting research priorities and evaluating practical approaches to improving their quality of life. The cause of my symptoms remains uncertain, but their impact is real. I urge HHS to take these experiences seriously, support rigorous research, and ensure that people reporting electromagnetic sensitivity receive appropriate medical attention. Thank you for considering my comments.

I am responding as a patient, advocate, and concerned member of the public. Ques.3(a)–(g) Personal Experience Six years ago, my environmental health physician diagnosed me with EMR syndrome. My exposures included extensive computer use in college, working in a Wi-Fi-equipped building with computer labs and a Smartboard, making hundreds of photocopies daily, and living near a cell tower. Combined with mold exposure and stress, these factors coincided with years of debilitating illness. Symptoms I have experienced from RF/EMFs include tinnitus, headaches, burning throughout my body, facial burning after watching an iPhone video, gum mucoceles/cysts after cell phone use, tingling teeth/jaw, hip pain while wearing a cordless FM-microphone battery pack, nausea after dental X-rays, and anxiety. I manage symptoms with a low-RF/EMF lifestyle: silver-lined clothing, an RF-shielding canopy when living near a cell tower, an RF Safe cell phone QuantaCase, a BluShield plug-in device, and use corded technology when possible. An EMF building biologist assessed my home with meters and helped reduce exposure. I also take calcium, magnesium, and supplements intended to support glutathione production and replenish minerals. Ques. 11(a), (f), and (g) Sensitive Populations I am particularly concerned about children. The Epoch Times article, How Screen Time Affects Different Organs, by Arsh Sarao (11/1/25), reports that excessive screen time may reduce gray matter in brain areas involved in decision-making and emotional regulation. I have observed irritability, aggression, hyperactivity, and obstinance in children after screen use, and anger, agitation, and depression in adults following wireless exposure. I have noticed calmer behavior after consuming mineral water and calcium-rich foods. These observations deserve further investigation. Ques. 13(f), (j), and (k) Cumulative Exposure Research should assess cumulative close-to-body RF exposure from wireless earbuds, smartwatches, hearing aids, and health monitors, including devices tracking atrial fibrillation and diabetes; some communicate continuously via Bluetooth and smartphones. Consumers should retain the option of analog electric meters instead of RF transmitting smart meters. Landlines do not emit RF and should remain available, with funding to maintain copper lines. Incandescent bulbs should remain an option, and electromagnetic interference from LED/fluorescent lighting should be studied. Ques. 14 Environmental Effect Research should examine possible links between RF/EMF exposure, mold, and mycotoxin illness. Dr. Dietrich Klinghardt’s research, referenced in the July 2014 Townsend Letter (attached; p. 10), reportedly states that molds exposed to high EMF levels release up to 600 times more mycotoxins and also proliferate faster. These effects could potentially exacerbate symptoms in individuals already suffering from mold-related illness. Ques. 16 Federal Research Priorities I respectfully urge HHS to review Dr. Andrew Goldsworthy’s "The Biological Effects of Weak Electromagnetic Fields" (attached). Goldsworthy proposes that electromagnetic fields may increase cell-membrane permeability, allowing calcium ions to leak into cells. Calcium regulates nerve signaling, muscle contraction, and inflammation; disrupted balance could affect multiple body systems and explain reported multisystem symptoms. Goldsworthy’s work deserves serious consideration and further study. In addition, The EMF Medical Conference 2021 recordings (see References) provide valuable research and clinical observations from physicians and RF/EMF experts and should be reviewed. Ques. 18 Recommendations I recommend that HHS consider the following: -Promote public service announcements and safer-technology education, especially for children, using Environmental Health Trust materials (see References). -Set school health standards for responsible technology use. -Expand public access to RF/EMF meters and detectors for purchase or rental. -Add EMF building biology tracks to college/university environmental science programs. -Encourage schools, workplaces, hospitals, and residential facilities to use qualified EMF building biologists for assessments and remediation. -Recommend that municipalities employ EMF building biologists to assess cumulative emissions from smart meters, cell towers, and other RF infrastructure. -Investigate exposure-reduction approaches discussed by Goldsworthy, including Balanced Signal Technology and resonance/scalar-frequency methods. -Limit X-rays and other imaging to medical necessity and explore tracking patients’ cumulative imaging exposure. Conclusion I respectfully ask HHS to investigate these concerns with scientific rigor, consider affected individuals’ experiences, and develop practical measures to protect public health while allowing people to make informed choices about technology. Thank you for the opportunity to share my experiences and views.

I am very concerned about 5g and Wi-Fi signals. These technologies are limited for health reasons through Europe, and several health researchers advocate against this technology. There are less popular resources on this available on less controlled search engines and databases.

I live in The Arena District in downtown Columbus, and there are all kinds of radiofrequency admitting antennas on the tops of buildings in the downtown. The exposure level outside on my 6th floor balcony is Extreme. The exposure level inside my condominium unit appears to be much lower, so it appears the construction materials of the building may be somewhat protective. I believe the building meets commercial construction standards. According to AntennaSearch Report, there are 41 Towers within 1.0 miles of 43215. The nearest tower is .24 miles away. Since I am inside most of the time, I have learned that the following things were increasing my RF exposure to either a High or Extreme level inside most areas of the condominium including radiofrequencies from the next-door neighbor's Wi-Fi and possibly other sources of RF coming through a shared wall into my bedroom. Also, the following items were being used in the condominium which contributed significantly to my exposure: -ROKU -Wi-Fi -a printer -a smart refrigerator -Alexa -a laptop computer and printer These measurements were confirmed by a Home EMF Assessment Report completed by Shielded Healing LLC. on 9/10/2020.

Hello, so my family and I have had the opportunity to live away from 5G and than again back into 5G. We were in an area for 3 years with 5G in our neighborhood. We had sicknesses often, and health issues constant. Whether it being sick as many times as every two months for sure we would get bugs and it would go through family. It was an older home so I figured that might have to do with it. We then moved into an area that has no 5G and surrounded by old growth trees. We all lived there for 1 year and through the worst bugs going through our schools and workplaces. We never got sick once in the whole year. Two winters…. Then we moved again to a new house back in 5G area. And we are now all getting sick constantly again. I would say more frequent. And bad sleeps. (Waking up so tired) We are now very close to a 5G box. And have seen direct correlation with our immunity and 5G. Our Immune system functions way better away from 5G. The house we were in when we moved away from 5G even had mold in it and dead animals behind the walls. That should have made us more sick. But it never. It was no sicknesses because we were far away from 5G. Also we only had one WiFi box in the house. At all times. But in the urban centers we are surrounded by neighbours with WiFi also… so that could be adding to it. But a huge difference when living urban with many signals compared to in an area that is away from signals, on our immunity…

My son had debilitating migraines when he was young. He would hold his head and rock back and forth in so much pain. Someone suggested we turn off our Wifi. I said that's crazy, how can we live without Wifi? We finally tried it as we were desperate. We hard wired everything and unplugged our router. He has never had another migraine!! That was 10 years ago! Many times when I stay in a hotel (with intense wifi and EMFs) I get a migraine. EMF sensitivity is real! Some of us feel the effects physically, but we are ALL affected. Most just don't realize it!!

I have had a continuous nonstop electrical sound hissing in my ears for 2 years now. (Tinnitus) I live about 2 blocks from a cell tower and live in a duplex with 5 adults on the other side of the wall using devices. I purchased a router cage and a block radiation case for my phone. With my living quarters I feel it’s a hopeless situation. I have noticed the further into the country side I go, it is significantly quieter. When I drive back to the city it increases again. It is hard to understand when people talk if there is other noise in the room. Thank you for investigating what is happening to the citizens of our country because of this radiation.

I gradually developed EHS after being exposed to many EMF sources, especially low frequencies, for a long time without knowing that they would harm me. In early 2010, I became more sensitive and started to learn about EMF and EHS. I later received a diagnosis confirming my EHS and realised that I had to avoid exposure and reduce oxidative stress by taking daily antioxidants. I have learned to survive in an electropolluted world, but this has meant making severe lifestyle changes. I can no longer go to meetings, the cinema, the theatre or concerts because of the emissions from smartphones, Wi-Fi and antennas. I cannot use public transport either, and it is difficult for me to access healthcare facilities for the same reasons. I actually have to stay in lockdown to avoid suffering. Is this a life?

As a worker with occupational exposure in the telecommunications industry, it became clear that distancing myself from Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation, and Wireless Radiation Exposure also removed the negative effects I was experiencing from these devices. 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.

Thank you for this initiative.. the RF radiation starting from microwaves , which I do use bit for no more than 3 mins for heating and not in plastic containers; all scientific researched informed decisions, many don’t know that cooking food since it changes food structure especially proteins, breaks their structure, so food becomes toxic to be consumed .. Also , pretty much all microwaves I have tested ( and I tested about 10) emit significant radiation ( in the red levels when growing g cells are killed) to the outside space while in use ( new and old models ); I have a professional RF measuring device and it reads at red levels next to it ( and most hang right above the stove , so brain is being friend if you are cooking while it’s on, consequence a headache or worse if continued); need to move away to about 6 ft to be clear completely and about 3 feet out of red zone. Same goes to the WiFi routers , their signals are eartic but never stop . The RF towers are terrible, I am not living next to one, but that radiation travels far, depending on the height and power of the tower. Definitely need to be investigated. I measured those as well and chose school and home away from them. The radiation effects that science shows : activates mold and bacteria in our bodies and creates the histamine , mast cell activation and antibody elevation related illness.
