Proposed biological mechanisms

I am a telecommunication engineering graduate and my comments are to be considered as an independent individual contributor. I experience ear buzzing, headaches and sometimes skin itch in the presence of EMF equipment such as WiFi routers and mobile phone base stations. To create exposure standards and risk assessment (questions 5. o. and 5.p) methods, several aspects need to be considered: - EMF intensity, variety and duration of exposure; - realistic testing use cases: a SAR measured in a lab might be different from an effective SAR of a phone placing a call from a driving car for example; - environmental base levels of EMF radiations: being in an urban, EMF rich environment after a week of camping is completely different than being in such environment contantly; - mental well being and psychological consequences related to the constant exposure to EMF and associated technologies; phenomena such as "fear of missing out", "feeling overwhelmed by work all the time"... - Federal research priorities (Q16): - how do EMF impact the bioenergetic field of the human body of sick and healthy patients; - what are effective and efficient shielding strategies for sensitive buildings and individuals; e.g. clothing, paints, Faraday cages - the right to be offline and the right to slow down technological use;

Dear HHS Leadership, Thank you for seeking public input on the biological and health impacts of radiofrequency electromagnetic fields (RF-EMF), including 5G, Wi-Fi, and personal wireless devices. As technology density grows in homes and schools, federal guidelines must urgently account for the heightened biological vulnerability of children. We request that HHS incorporate the following science-based protections into its safety evaluation and public guidance: Child-Specific Absorption Modeling: Current federal guidelines are based on adult male anatomical models. Research demonstrates that children—due to thinner skulls, smaller head dimensions, and higher tissue water content—absorb up to twice as much RF radiation into their brain tissue and up to ten times as much into bone marrow compared to adults. Impacts on Developing Neural and Cellular Systems: Review peer-reviewed evidence showing that non-thermal RF exposure can induce oxidative stress, mitochondrial dysfunction, and altered intracellular signaling in rapidly dividing, developing tissues. Public Warnings and Device Labelling: Issue clear public health warnings regarding cell phones and wireless devices. Recommend practical limits, such as keeping devices away from the body during transmission, using speakerphone, and avoiding cell phone use directly against a child's head. School and Childcare Environment Limits: Establish guidelines for educational settings, including favoring wired ethernet over Wi-Fi in early childhood centers, turning off Wi-Fi routers when not in active use, and restricting small-cell deployment directly adjacent to school grounds. We urge HHS to align U.S. policy with international precautionary standards and provide clear, actionable guidance to protect developing children. Sincerely, Abigail Crowe

I am responding as an individual consumer. I have experienced trigeminal nerve pain and eye pain from 5G EMF exposure, most notably as emitted from cellphones when held close to my head by others to show me something on their cell screen. For this reason, I have limited my exposure to such devices, now keeping my head several feet away whenever possible. For this reason, I also had the titanium posts taken out of my jaws that had anchored my implanted teeth. The titanium was replaced with oxidized zirconium. Since then I've had less pain with EMF exposure, but it is still there to some extent. The titanium posts had been picking up the EMFs like an antenna-- and strengthening the pain signal as it traveled up my trigeminal nerve. I noticed this became a huge problem soon after the advent of 5G transmission, which we know is multitudes stronger than 4G. 5G radiation, while non-ionizing, is composed of much shorter wave lengths that cannot travel as far--but more readily penetrate buildings and people's bodies. I continue to try to limit my exposure to EMF radiation, using wired computer connections and my cell phone sparingly in preference of a wired landline connection. Before getting the titanium posts extracted from my jaw bone, I even experienced picking up of a few seconds of a local emergency services communication! Whatever we can do to limit or curtail 5G or 6G exposure to the general public should be done. I understand that the military might need it for modern weaponry systems. In my view, the rest of us would be healthier without it. Thank you.

Please look into how 5G towers placed on roofs of elderly/disabled HUD apartment buildings (in Buffalo, Erie County, NY) affects tenants whose apartments and windows are in the direct line of site of these towers. One example of the many dangers to tenants is overheating of metallic implants by the 5G radiation. My titanium dental implants were directly affected causing severe pain, nausea, radiation poisoning symptoms etc. until I was forced to remove them. My biologic dentist's X-rays showed the implants affecting the adjacent bone. The implants became detached from the bones causing the implants to be loose and easily slip out so they could then be replaced with ceramic implants. The ceramic replacement alleviated all the dental problems. I am still exposed 24 hours per day and still have other symptoms that are not as well or easily documented that I cannot alleviate, and which I am very concerned about. We have known for decades that high EMF exposure degrades collagen and thus undermines the integrity of the entire body. Please address this before additional irreversible, tragic health problems develop. PLEASE HELP remove or deactivate these 5G towers from roofs of elderly/disabled buildings in Buffalo, Erie County, NY until the safety issues are addressed. These 5G towers were placed March 2021 during the COVID pandemic when my symptoms of radiation poisoning began. PLEASE PLEASE HELP! Thank you!

EMFs have something to do with the calcium channels of our cells. Studies have been done but aren’t very detailed. People are getting “cavitations” from losing teeth or getting wisdom teeth removed. Why is bone not healing? My grandmother was widowed in her 30s when her husband who was a lineman had a massive heart attack. There’s possibly some sort of correlation with frequencies and our calcium channels. I think it should be looked into.

I only know that is seriously harmful and damaging to the cells of every living creature human being. I would love to get more professional help and advice, insights how to protect ourselves against it. If I’m well informed then one should consume a lot of fresh fruits and veggies, drink tons of clean purified water. Hidrogen water is best. Get as much movement, fresh air, sunlight as possible. Could you please help and advise what more is there to be known.

I am submitting this comment in response to HHS’s Request for Information on Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation, and Wireless Radiation Exposure. Neurosurgeon Dr. Jack Kruse views wireless radiation—cell phones, Wi-Fi, 5G, and other man-made “non-native electromagnetic fields” (nnEMF or non-native EMF)—as a major driver of modern disease through disruption of mitochondrial function, cellular water structure, circadian timing, and quantum biological processes. Robert O. Becker's work found proved these same drivers of disease. Kruse emphasizes non-thermal (not just heating) effects and links them to quantum biology: Mitochondrial dysfunction and water disruption: nnEMF impairs mitochondrial water production, causes cellular dehydration, increases reactive oxygen species, raises mitochondrial heteroplasmy, and reduces energy efficiency. Water is described as a carrier of electromagnetic information from the sun into cells; microwaves and nnEMF disrupt this. Stress response and signaling: It triggers a massive cellular stress response mimicking leptin resistance, a heart attack, or panic attack. It can cause chronic sympathetic nervous system overdrive (“microwave sickness” described in older Russian literature), leading to poor sleep, adrenal issues, cardiovascular problems, and more. Calcium signaling, DNA, and other effects: Interference with calcium secondary messengers, non-linear DNA damage, disruption of synchronization with the Earth’s magnetic field, and impaired cellular timing/coherence. Reproductive and developmental impacts: Kruse specifically warns against keeping phones in front pockets, citing potential effects on sperm, testosterone, and germ cells (with implications for offspring). He has discussed fertility concerns more broadly in the context of device proximity and urban/wireless environments. Kruse frequently references the U.S. National Toxicology Program (NTP) animal studies (showing associations with certain tumors in rats from cell-phone-type RF radiation) and older Russian research on microwave effects, arguing that safety standards based only on thermal effects are inadequate. the negative health impacts of wireless radiation are real and proven. I support HHS taking an active role in examining the potential health and environmental effects of wireless radiation. Questions about human health should be addressed by federal agencies with appropriate expertise in medicine, biology, epidemiology, and public health, and the experiences of individuals and families who report being affected should be considered alongside the scientific evidence. I urge HHS to carefully evaluate these experiences and the scientific evidence, identify gaps in current research, give particular attention to children and other potentially vulnerable populations, and establish appropriate federal research priorities regarding wireless radiation and public health. Thank you for providing individuals and families with an opportunity to be heard.

Wireless radiation is not harmless, as proven by scientific studies demonstrating the cellular damage the human body can sustain due to exposure, increased cancer risk after repeated exposure, and as evidenced by many fire departments refusing to consent to cell antennae on their structures, or within a certain distance from their structures. Please ensure the safety of American citizens by listening to the science and responding to it.

COIL WHINE, coming from multiple electric items everywhere, is perceived by a percentage of people with sensitive hearing, causing their Central Nervous System to be on high alert, with symptoms like bad to debilitating reactive tinnitus, perceiving certain sounds as painfully loud, distressing electric feelings in feet, hands and head especially when lying in bed above a wooden floor under which are recessed halogen lights with all their transformers emitting coil whine, brainfog, a feeling of being paralysed out of doing what you really want to commence and finish. I feel this part is worse possible during the day because I am within reach of 18 active and strong wifi networks and many more phones and laptops during the day and evening. In my case my hearing is excellent (says ENT) and I have small fibre neuropathy (says neurologist) and prediabetes (says gp). It seems my metal dental restoration materials, like a bridge and a lot of White Composite Filling materials which almost all contain metallic nanoparticles, cause the high sound vibrations to travel through jawbone conduction more then through natural teeth which are less dense material, going straight to the inner ear and byoassing any muffling in the earcanak ir eustachian tubes. My eustachian tube is either permanently closed or open, my next ENT specialist will find out. This also effects how sound gets to your inner ear. I beg you look into the combination of COIL WHINE, small fibre neuropathy, prediabetes, metal in dental work including white composite filling material surrounding molars, excellent/sensitive hearing, eustachian rube dysfunction, and multiple wifi networks and machines surrounding a person especially in high density small apartment and studio living.

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.
