Describes headaches during electronics inspection and phone use, later dizziness associated with home Wi-…

Thank you for the opportunity to comment. 2. I have experienced health problems as an individual worker and consumer. 3. Headaches In the 1990s until 2001 when I was laid off, I inspected consumer electronic equipment. There were two equipment setups and one type of product that caused headaches. The headaches reminded me of lightning: sharp, intense pain for a very short period of time. They frequently occurred in groups of three. The groups might be repeated a couple of times during the hour. Then there might be nothing until hours later. As far as I remember, they occurred at work, starting the second day that I inspected the same type of product as the previous day. It was a delayed reaction: I never got these headaches on the first day. Equipment Setups (the products had been inspected using other equipment or arrangement of equipment that did not cause a problem): - Computer monitors inside a Helmholtz coil: the inspector was on one side, the electronics on the opposite side of the coil, and the monitor in between. A large number of monitors were inspected in this manner for a year. Everyone who did the work got headaches although they were different types of headaches. - Stereo receivers: equipment used to check the inputs and outputs was placed on carts within arm’s reach, resulting in amplifiers and speakers being very close. Products: telephones, usually cordless but a few cellphones also. __________ Later, long after I left the job, I needed a cellphone. I got a flip phone and had no problems. Then technology changed to smart phones. I got a weaker version of my previous headaches: a delayed reaction of 1.5 to 2 days, less pain that lasted longer, and all pain was gone within three months from one phone call. Now, I do not use any kind of mobile phone. __________ a. Mobile phones, cordless phones; electronic equipment with higher than normal magnetic fields, or possibly dirty electricity b. Work environment: exposure to Helmholtz coil was frequent for a year; others infrequent. In other words, we spent more time inspecting computer monitors than cordless phones or stereo receivers. c. Headaches d. The headaches appeared the second day of working in a Helmholtz coil and continued until I had a break from inspecting monitors (I do not remember how the weekends affected the headaches). e. Treatment is to stop working, which eventually happened. f. Our boss did not believe us and said that the coil should provide a healthier environment by providing a uniform magnetic field. ____________________ ____________________ Dizziness I live in an apartment building in an urban area. Across from my apartment is the community room with free Wi-Fi, which I can use in my apartment. One of my symptoms is a balance problem: sometimes, I would feel like I am walking at an angle, occasionally even needing to hold onto something. Many months after I got my own internet service (Wi-Fi), I noticed that I was getting dizzy more often and had to stop walking or reach out for support. The only thing that had changed in my life was the new internet service. I eventually returned to using only the free Wi-Fi from the community room. The dizziness and balance problems decreased, eventually going back to a normal level. Since I am now aware of the problem, I would estimate that it would take about six weeks to know that I am getting too much exposure to WiFi. The change happens very slowly. I will need to shield my apartment and have all components of my computer system wired, including wired modems and routers that do not emit Wi-Fi. __________ a. Wi-Fi b. Whenever I am at home, which is most of the time – 24/7. c. The identified health effect is dizziness. The potential adverse health effects include fatigue, poor memory, poor sleep, tinnitus, irritability, weakness, and pain. d. Several months. Now that I know there is a problem and am looking for a change, and usage of the second Wi-Fi connection is almost eliminated (or excessive), I can identify it in about six weeks. e. Treatment is to stop using and being exposed to Wi-Fi: that should decrease or eliminate dizziness and balance problems. f. I need to shield the apartment (only a little has been done), buy modems and routers that do not emit RF/Wi-Fi, and run shielded cables where needed. To do this, I need money, energy, and feeling comfortable standing on a ladder. Very little has been done. I have not noticed any effect.
