The commenter reports sleep, HRV and family changes associated with wireless exposure and reduction, and …

I am responding to HHS's request for personal experiences with RF/EMF exposure and for input on disclosure, exposure standards, and research priorities. I am writing as an individual and as a husband and father in a household of five, including three children. I am a Navy veteran who served as a Hospital Corpsman, and I now work in technology, so I am comfortable with the devices involved and with tracking my own physiological data. What follows is based on personal experience and my own wearable data, not on clinical research. I first noticed a problem in 2008 while using a wireless gaming controller. Gaming sessions consistently left me feeling unwell, and only after that pattern repeated did I search online and find that other people were describing similar reactions. The symptom came before I had any idea that others were reporting it. I likely had been affected before that point without recognizing the cause. The effect I experience is a stressed, overactivated nervous system. I track this with an Oura ring. With Wi-Fi present, my deep sleep drops from more than an hour per night to about 30 minutes, and my average heart rate variability falls steadily from 50 to 60 ms to the high 20s or low 30s. When this stress persists, I get sick more often and my mood becomes less stable. In heavy Wi-Fi environments my sleep is affected that same night, and I often become dizzy to the point of needing to lie down. In 2008, we removed Wi-Fi from our home. I felt noticeably calmer almost immediately. Over the following [weeks/months], my children argued and fought much less, and my wife's frequent migraines stopped and her mood stabilized. Removing the router was not enough. Many household products contain Wi-Fi or Bluetooth radios that transmit continuously or keep searching for a connection even when they are not in use, and most give the owner no way to turn them off. To get our home to a low exposure level, I had to physically remove the wireless chips from our television, garage door opener, gaming consoles, and remote controls. Most households could not do this, and most people would not know these devices are transmitting at all. Based on that experience, I would ask HHS to consider two things. First, products should clearly disclose every radio they contain, whether it transmits while idle, and how often. Second, consumers should have a reliable way to disable those radios, ideally a physical switch, without losing the product's basic function. Right now the only way to opt out is to take the device apart, which is not a realistic choice for families, schools, or people who believe they are sensitive. I would also ask HHS to look closely at cumulative exposure in suburban areas. In communities near me such as Fishers, Indiana, 5G infrastructure has been deployed densely into residential neighborhoods. Residents now live with that infrastructure on top of their neighbors' Wi-Fi routers and the phones, tablets, and computers in every home. No single source may exceed federal limits, but no one is measuring or accounting for the total. Because federal law prevents local governments from denying these installations on health grounds when they meet FCC limits, residents have no local recourse. The federal standard is effectively the only protection they have. Other countries have chosen more precautionary limits. Switzerland and Italy, for example, set much lower limits in places where people live, sleep, and spend long periods of time, including homes and schools. HHS should examine these approaches and the evidence behind them as it advises on whether current U.S. limits, which date to 1996, are adequate. Finally, I would encourage research into whether biological effects depend on how signals are transmitted, not only on how much power they carry. Modern wireless signals are pulsed and modulated in complex ways. If certain modulation or pulsing patterns turn out to matter more than others, that knowledge could guide the development of wireless protocols that are more compatible with human biology while still delivering the connectivity people rely on. Wearable HRV and sleep trackers could offer a low-cost way to study this in real-world settings, especially where participants do not know whether a transmitter is on. In short, I ask HHS to support clear disclosure of every radio in consumer products along with a reliable way to turn them off, to evaluate cumulative neighborhood exposure rather than single sources, to review the more protective limits used in countries like Switzerland and Italy, and to fund research on whether modulation and pulsing patterns drive biological effects.
