Li-Fi, fiber & alternatives

I am submitting this comment in response to HHS’s Request for Information on Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation, and Wireless Radiation Exposure. I am responding from the perspective of a family member of a person impacted by EMFs. The lady in question had huge headaches, ear ringing, sleepless nights, increasingly irritable, caused problems in her family. I told her to turn off the wifi router as much as possible, she could only turn it off during the night. It made all the difference. All symptoms disappeared within a few days. My family had short livied similar issues, which made us hard-wire our house and use blocking materials on our walls and windows. We now have no issues, long gone.

Evidence shows that wireless radiation is used as a bioweapon as quite crimes against humanity. This is unacceptable and illegal. Wired technology such as wired lan lines and ethernet are much safer and secure options for technology. Wireless devices should only be used in emergency situations.

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 presume this book has already been recommended, "The Body Electric" However I would like to add a couple personal ideas: In the past, the stereotype of "Tin Foil Hat" has been associated with conspiracy theory. I have wondered, what would make these particular people sensitive to EMF enough to wear tin foil? My thought is that they could have higher heavy metal content in the body that might act like an antenna. This could be from vaccines or from environmental exposures. If mercury ultimately ends up in the brain stem, it would make the tin foil hat even more applicable in blocking signal to the otherwise minimal heavy metals in the body. Even braces have been joked as being able to pick up radio waves. Another idea, I think for this and many other reasons, in home saunas should be subsidized for every American to build with HSA funds. This would also strongly help combat plastics in the body thanks to the personal studies by Bryan Johnson. Another idea, I think every school should be made into a complete Faraday cage, potentially with lead paint under siding to prevent exposure, so that students and teachers are made to be present in class, as well as cut exposure to EMFs in school. I believe it can be argued that it does not serve our children to have in their pockets the most distracting thing of all time during class. I believe in the event of emergencies, old fashioned wired telephones should work just fine. A small addition to that is standardize the books please, there's no reason college education requires buying new editions on old information. Standardize academics and remove extra curriculars, make those into community classes without pay. The classic books need to be in schools again. Wiring in walls could be made into a grid to power the building as well as cage external EMFs with enough grounding, I say this as an aerospace electrician, however every building would need special engineering, and doing so would cost a ton more copper, but could be measured inside of each room with a sensitive RF meter or even an oscilloscope for measuring the wavelengths exposed to, as in The Body Electric, specific frequencies and pulsing matters as well. I may even just recommend the final chapter of the book. Maybe we can control for Russian standards in home/school/work areas. I think home standards could include the use of piling earth alongside sturdy walls as a form of EMF shielding, similar to living underground. This could provide safe EMF exposure at home without the high demand for conductive metal for a faraday cage or lead paint for a complete blockage of EMF fields. I think studies should be done in the wearing of polyester, which generates static electric charge stored on the body. If my instinct is correct, this is bad for the body, as it makes me feel bad until I am grounded by ESD shock. If this is true, we should move towards natural materials. I think trade for more agriculture could improve, I know Ireland has had to throw away excess wool or use it to nourish farm soil rather than sell it. My final suggestion is if we upgrade the grid to provide nuclear power is that we bury the power lines. Europe does this, and I think especially in tornado alley this is not only safer but the EMF exposure is automatically grounded by being under the earth, plus it should be easier to work on. Thank you for reading. I suspect I negatively impacted my health working in electrical testing, operating DITMCO machines for nearly a decade. I wonder if these electric cars will have high EMF production. I also wonder if we should incorporate jewelry that acts as a capacitor so that we never store an ESD charge in our bodies. The book The Body Electric is required reading on this subject. Please, read it.

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!!

Re: Electromagnetic Fields, RF Radiation, and Wireless Radiation Exposure Question 2 — Perspective I am commenting as an EMF affected individual and writer who has covered wireless radiation and public-health concerns for years. This reply offers policy recommendations informed by government reports and my review of this subject, rather than original research or clinical findings. I welcome HHS’s examination of RF/EMF exposure. The public deserves a transparent assessment of whether existing protections adequately address today’s exposure conditions, particularly for children and other potentially vulnerable populations. Questions 5–6 and 12 — Exposure standards and health evidence I urge HHS to independently reassess the scientific basis of current federal exposure limits. Protection against established heating effects should not substitute for evaluating potential effects from long-term exposure at lower intensities. Please critically examine research concerning oxidative stress, DNA damage, reproductive and developmental outcomes, neurological function, and sleep. Reviews should distinguish association from causation, and experimental exposures from realistic human exposures. Where findings conflict, HHS should explain how exposure measurement, temperature control, sample size, study design, replication, and funding sources affect its conclusions. Uncertainty should be acknowledged rather than presented as proof of safety. Questions 8–9 and 13 — Real-world exposure and disclosure Exposure assessment should reflect how people actually use technology: phones against the body, wearables used for extended periods, and overlapping emissions from devices and infrastructure. HHS should evaluate how duration, proximity, frequency, modulation, and simultaneous transmissions affect exposure and the interpretation of health studies. In 2012, GAO recommended reassessing the FCC’s exposure limit and phone-testing requirements, particularly for use against the body. Its report page currently lists both recommendations as closed without implementation: https://www.gao.gov/products/gao-12-771 HHS should work with the FCC to address these concerns and improve consumer disclosures. Any separation distances or operating conditions required for compliance should be prominent and understandable, rather than buried in technical instructions. Question 11 — Children and potentially vulnerable populations Children’s developing bodies and the possibility of lifelong exposure beginning early in life warrant specific assessment. HHS should explain whether existing safety margins adequately address children, pregnancy, and other potentially vulnerable groups. Research should include long-term developmental outcomes and exposure patterns in schools and childcare settings. People reporting electromagnetic sensitivity should receive respectful clinical evaluation and rigorous investigation of their symptoms, possible contributing factors, and effective management approaches, without presuming an established cause. Questions 14–15 — Environmental and infrastructure considerations HHS should coordinate with environmental agencies to assess potential effects on wildlife, pollinators, plants, and livestock. Human exposure limits should not automatically be assumed to protect other species. Infrastructure assessment should incorporate measured exposure and cumulative neighborhood conditions. Distance from an antenna alone is an incomplete measure; transmission characteristics, direction, terrain, and other sources also matter. Questions 16–18 — Research priorities and practical action I urge HHS to fund independent, reproducible research on chronic exposure, childhood development, reproductive health, neurological outcomes, and plausible biological mechanisms. Priorities should include longitudinal studies with better exposure measurement and replication of important findings. Research funding and advisory processes should disclose relevant industry relationships and protect scientific independence. HHS should publish its review methods, evidence assessments, research priorities, and a timetable for public updates. While research continues, HHS should evaluate and communicate practical, low-cost ways to reduce unnecessary exposure, including wired connections where feasible, greater distance from transmitting devices, disabling unused wireless functions, and the use of scientifically researched EMF protection devices like Blushield. Guidance should explain the evidence and remaining uncertainties. Please use this RFI to produce meaningful research commitments, clear public guidance, and recommendations to strengthen federal protections wherever warranted. Families should be able to benefit from communications technology while receiving an honest account of what is established, what remains uncertain, and how avoidable exposure can be reduced.

I began developing physical symptoms including dizziness, pain in my skull, a sense of passing out, after taking advanced courses at the University of minnesota. I was supposed to be a computer software trainer. But the more I was exposed to high-end computers as they got stronger and stronger, the more my body started reacting. I developed in ovarian cyst for the first time after using a keyboard on my lap because of physical disabilities I couldn't sit up right and I had to sit sideways..... My first experience with a wireless mouse that worked on several gigabytes versus a wired mouse that I'd used for several years, my first experience with a wireless mouse is that it actually caused scarring on the right upper part of my arm. I stopped using it. Eventually with help from a friend and assistance from techies in the disabled community, we were able to put together a computer system that I was able to sit several feet back from. Using a wired mouse. But this was just the beginning of increasing problems. Remember, I was supposed to be a computer software trainer and I ended up with a bachelor in science from the University of Minnesota but wasn't able to do the work with a combination of multiple physical disabilities increased including increasing sensitivity to the technology as it got stronger. As I found myself nearer to cell phones that were becoming prolific (I was still using a landline telephone), and were being used by people in my life, I found that I could physically feel the energy from them that felt very uncomfortable and actually painful, within 15 to 20 feet of their use. When I found myself in a nursing home at the beginning of the pandemic after I lost my apartment due to multiple disabilities and a lack of PCA help, I was inundated by technology all over the place. Large flat screen TVs in public areas that I found myself not being able to be around, I didn't put a TV in my room at all, (when I was in my apartment I still was watching a small cathode ray tube TV, 6 ft away from it)... Anyway, people had cell phones all over the damn place, laptops, large TV screens, every single patient seemed to have some kind of large TV in their rooms, and if my room was next to a person's where the flat screen TV was up against my wall, I physically felt the electricity and I couldn't sleep. Exposure to all of this technology became more and more problematic. Eventually I started actually collapsing near the nurses station where there was so much technology in use and which was right near one of the gigantic large flat screen TVs used by the public community here. I actually started collapsing. I do have a history of autoimmune and inflammation diseases for several decades, and a history of brain damage going back several decades as well. But never collapsing. I got tested for epilepsy. I do not have epilepsy. However the electricity they used in the room to do the testing was so intense, I actually collapsed outside of the room before we could even do the testing. The problem is that I had become so ultra-sensitive to a combination of radio frequencies, EMF fields, RA's, electricity leaking through walls of this old nursing home that couldn't handle high-end technology, or proliferation of cell phones, and I just became sicker and sicker. My functional medicine doctor knew that this was a real physical ailment and diagnosed me with what is being called electromagnetic hypersensitivities. She knows it is real. It was terrible when some of the staff here started believing that I was acting out emotionally by collapsing on the floor. No, my brain and nervous system and all the cells in my body were reacting to the excessive exposure to all these different kinds of energy fields that were pummeling my body. So she gave me the diagnosis. And hold the staff unequivocally that this is real. So they stop pretending this is emotional. This is a real physical ailment. Unfortunately I've been forced to use a cell phone because there are no landlines in this nursing home except for staff. Which puts me in an exceptionally dangerous situation. I'm also concerned that there's talk about ending landlines in the united states. Which I believe would be a really dangerous as more and more people are realizing that excessive cell phone technology is dangerous. We are destroying ourselves, our bodies, probably other things in nature. When I don't absolutely have to use my cell phone as I am now to dictate this, I will put my cell phone on airplane mode and turn it off. And I have become concerned about the proliferation of cell phone towers and that cell phone companies are trying to keep increasing their power. Right now I am on a 4G cellphone and I don't want it to get any stronger. You need to do something to stop this danger that is being caused to all of us. Like cigarette companies making money off of our health problems 50 years ago, you need to stop these technology companies from doing the same.

Since 2005 when Wi-Fi became available in my local area, I have suffered radiation sickness whenever I enter a building infested with WI-Fi antennas. This includes ALL businesses, ALL federal, state and county buildings plus ALL medical buildings. My worst symptoms are painful headaches and severe tinnitus that does not resolve for hours. Both of these conditions develop immediately upon my entering Wi-Fi polluted buildings. Of course I cannot avoid this misery since as a human being, I am forced to enter highly-polluted buildings in order to meet my needs including groceries, medical/dental consultation etc. At the same time, the latest science confirms what is making me sick is a carcinogen. Because my neighbors send their Wi-Fi into my home, I am forced to screen my home with protective materials that keep trespassing Wi-Fi out of my living space. This effort is very expensive and alienating. We need a national effort to develop fiber to communities and to all buildings so that the human environment becomes less miserable and potentially deadly for all of us. My personal Wi-Fi is cabled and I have all Internet amenities I need without Wi-Fi. Public buildings and homes CAN be made safe without loss of connectivity. HHS PLEASE HELP clean up our radiation-toxic environment for public health and safety !!!!

I am submitting this comment as a consumer concerned about long-term exposure to wireless radiation from phones, Wi-Fi routers, cell towers, and other connected devices. I urge HHS to conduct a thorough, independent review of whether current exposure limits adequately protect public health. This review needs to consider those most heavily exposed and should examine potential effects beyond tissue heating, including evidence concerning cancer, reproductive health, and children’s development. Please prioritize research that reflects how people actually encounter wireless radiation: repeated exposure over many years, often from multiple sources and devices used close to the body. Assessments should consider signal strength, pulse patterns, duration, and combined exposure. Please consider Melnick and Moskowitz’s 2026 analysis of animal data, which argues that existing exposure limits may inadequately protect against cancer and reproductive harm (https://doi.org/10.1186/s12940-026-01288-6). I also ask HHS to evaluate Lai and Levitt’s review of exposure intensity, duration, and signal modulation (https://doi.org/10.1080/15368378.2022.2065683), and Scarato’s review of US regulatory gaps and proposed reforms (https://doi.org/10.3389/fpubh.2025.1677583). These papers warrant careful consideration alongside the broader evidence, including studies that have not found adverse effects. I ask HHS to: •Assess whether additional protections are needed for children, pregnant women, and other potentially vulnerable groups. •Support long-term research with safeguards against industry conflicts of interest. •Provide clear information about exposure and practical ways to reduce it, including wired alternatives in homes and schools. •Recommend updated standards wherever the evidence shows that existing limits are insufficient. Consumers should not have to navigate these questions alone. Please use this inquiry to advance transparent science, meaningful oversight, and public health protection.

I am submitting my comments as an individual consumer. I first experienced physical symptoms of nausea when the agency I worked for installed several desk top computers for the secretarial staff in 1990. I was in Barnes and Noble and a staff person showed me how to operate a Nook. My reaction was immediate and I felt faint and almost collapsed. As more devices that use wifi and radio frequencies have come into use I have physical reactions to cell phones, tablets, smart meters, my husband's hearing aids, Wi-Fi signals within businesses, desk top computers in groupings such as in libraries or retail electronics businesses and singly in my husband's in-home office, electric grids in floor heated concrete slabs, underground electric service feeds to residences, high tension power lines, cell phone towers, routers that broadcast Wi-Fi to multiple devices within a home or business, security systems that use Wi-Fi, ungrounded knob and tube wiring in residences, electric and hybrid vehicles that have storage batteries, and in vehicles that use Sirius radio, Bluetooth, backup cameras, and other warning devices dependent on radar and radio frequencies. The most frequent and consistent physical reaction I have to EMFs and RFs is burning sensation that first begins in my hands and feet and then migrates to the skin surface of my entire body. More extreme reactions include nausea and disorientation and shortness of breath. These symptoms will occur within 3 to 10 minutes from the time of exposure. Removing myself from the physical presence of the source does not immediately lessen the painful sensations which can persist for 30 minutes or more from the time of exposure. Grounding my body by standing barefooted on the earth or in water will help the sensations diminish within 30 to 60 minutes. My most used method of avoiding the painful effects of being in the presence of EMF, RF, and wireless radiation is to avoid the physical locations in which those forms of radiation are present. I do not fly on airplanes. I have stopped going to entertainment venues in which the audience's use of cell phones is not prohibited. I do not visit certain friends who have smart houses wired with WiFi. I cannot drive a car any newer than 2011. My husband uses cell phone outside of house and uses computer when I am not home. We had our house rewired in 2019, removing the knob and tube and replacing it with metal wrapped cable and all grounded outlets. We have shielded one side of our house from a neighbor who has a smart wifi connected house. My strategy is to avoid, put distance between my body and the source, remove myself as quickly as possible from any environment with these forms of radiation, use a copper wired land line, depend on my husband to use the computer for internet connections and communication. He is the one writing these comments for me. For many years (1990 to 2019) I did not connect the occurence of these physical symptoms with radiation sources. In 2019 we had our house evaluated by an electrian and found that I had been exposed to high levels of electromagnetic radiation due to the knob and tube wiring. Since then I have been able to correlate symptoms with sources of radiation. The steps we have taken have reduced the frequency of symptoms within our home. I have asked for neurological examinations from Kaiser Permanente and clinicians there do not subscribe to the correlation between my experience of symptoms and exposure to radiation. I am writing this in the hope that my experience will add validity to the experiences of others like me.
