Endres\nWireless Technology (EMF) Health Symptoms\nOctober 2, 2012 to present (2026)\n\nOn October 2, 2012 a “smart” water meter was installed at the Biotechnology facility that I worked in.\nApprox 30 minutes after the “smart” water meter installation, I began to feel ill while working in our office area. My symptoms included: headache, nausea, difficulty focusing on my work, a metallic taste in my mouth, rapid vibration of my temple veins, and painful neck lymph nodes.\n\nI left the office area, and walked to my bench in our laboratory area. I stayed in the laboratory for the remainder of my work day. The painful symptoms subsided, and I left the building to go home.\n\nWhen home, I tried to make sense of what happened to me in my office area. I knew that there was a WiFi Repeater on the power cable approximately 15 feet from our office window. Could the WiFi Repeater somehow be interacting with signals from the “smart” water meter?  There were over 20 scientists in our facility, but I was the only individual to experience adverse health symptoms. While at home, my symptoms disappeared. I began to document my symptoms.\n\nI returned to work the following day and while at my office desk the painful headache and other symptoms returned. I had to leave work and went home, and my symptoms slowly dissipated.\n\nOver the next 5 work days, I documented my symptoms at work and tried various shielding methods and finding safe areas (laboratories, break room, etc.). I began researching papers regarding health impacts of man-made electromagnetic fields (EMFs) of wireless technology. I purchased a TENMARS TM-195 3-axis RF Field Strength meter, and EMF protective clothing from Less EMF, Inc. I measured the temperature of my head at various locations. I decided that I would be a “guinea pig” and record and document the EMFs at various locations in our facility.\n\nBrief summary of symptoms and measurements from my 5-day study\nOverall Symptoms while at work: headache, nausea, difficulty concentrating on tasks, shakiness, pain in the back of my neck at the base of my skull, rapid and painful vibration of my temple veins, stomach queasiness, pulse and heart rate variability, left eye pain sensations, shortness of breath, heat sensations around my head, “metallic mouth taste”, shakiness or quivering of my legs, etc.\n\nµW/m² range of values using the RF Field Strength meter, October 10, 2012\nBackground test of RF meter at home: 0--200 µW/m²\nRange of µW/m² values at my desk on 10/10/2012, 9:55 am to 11:15 am: 960.8 – 2,070 µW/m²\n\nAt 11:15 am I left our facility as I was not feeling well and when I reached my car I had a seizure where I lost control of my legs. After a few minutes, I slowly made it back into our facility. I was taken immediately to our company Dr at our main facility and she confirmed that I had a very serious seizure and that I could not risk having another seizure (as it could cause very significant harm).\n\nTwo months prior to my EMF symptoms, I had an annual medical exam and was given a clean bill of health.\nI had MRI and EEG exams after my seizure—they did not reveal anything of concern.\n\nSeveral days after my seizure, our department head walked into our office area and he asked me: “John, do you know that there is a WiFi router in the upstairs conference room, directly above your head?” Oh my goodness! I was not aware of the WiFi router directly above my head. This may explain a lot.\n\nI have been researching the health impacts of wireless technology ever since my experience with the “smart” water meter” incident at the biotech facility. I immediately found two books by Dr Robert Becker: “The Body Electric” and “Cross Currents”. In his book “The Body Electric”, on page 284, under the subheading “Fatal Locations”, Dr Becker writes in the 2nd paragraph six sentences that have stuck with me ever since my episode with the “smart” water meter:\n\n“The major problems come from extremely low frequencies (ELF), but higher frequencies have the same effects if pulsed or modulated in the ELF range. This is very often the case, for, to transmit information, microwaves or radio waves must be shaped. This is done by interrupting the beam to form pulses or by modulating the frequency or amplitude (size) of the waves. Furthermore, today’s environment is a latticework of crisscrossing signals in which there’s always the possibility of synergistic effects or the “construction” of new ELF signals from the patterns of interference between two higher frequencies.\nTherefore, experiments in which cells or organisms are exposed to a single unmodulated frequency, though sometimes useful, are irrelevent outside the lab. They’re most often done by researchers whose only goal is to be able to say, “See, there’s no cause for alarm.”\n\n","attachments":[],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-4098","tags":["health-experiences","sleep-cognition","exposure-places","research-evidence"],"source_hash":"3fe32fd3a06399c2732c7b3d4959606fcc7aeb2d8e0a9dc9c3ae511b6c325942","slug":"health-experiences-comment-4098","classification":{"id":"HHS-OASH-2026-0397-4098","body_sha256":"06affd1bc581dd54c63150ed634ef5b968b1a92cbcbd2bff8b71e08967313c22","status":"ai_reviewed","primary_topic":"occupational","topics":[{"id":"occupational","evidence":"2 a “smart” water meter was installed at the Biotechnology facility that I worked in.\nApprox 30 minutes after the “smart” water meter installation, I"},{"id":"smart-meters","evidence":"2012 to present (2026)\n\nOn October 2, 2012 a “smart” water meter was installed at the Biotechnology facility that I worked in.\nAp"},{"id":"wifi","evidence":"asked me: “John, do you know that there is a WiFi router in the upstairs conference room, directly above your head?” Oh m"},{"id":"neurological","evidence":"s not feeling well and when I reached my car I had a seizure where I lost control of my legs.
