The commenter reports sleep differences around active Wi-Fi while acknowledging observational limits, and…

I am submitting this comment as an individual citizen to share my day-to-day observations regarding wireless devices, living spaces, and overall well-being. ​When discussing how environmental factors might impact people, it is easy to assume that everyday lifestyle issues—such as diet, general stress, screen habits, or irregular sleep hours—are the only things driving changes in how rested or balanced someone feels. Over time, I have tried my best to pay close attention to these patterns and adjust my surroundings to see what differences I could notice. ​Even while making an effort to keep my general habits, diet, and schedule consistent, I have repeatedly noticed a practical difference in my sleep quality and how relaxed my system feels depending on where I am physically located relative to active Wi-Fi equipment. Using a handheld RF meter (a Safe and Sound Pro II) simply as an informational tool to check local signal levels, I noticed that areas right next to active routers or transmitting equipment consistently lined up with more restless nights and feeling less recovered overall. ​Conversely, when devices were turned off, unplugged, or moved farther away from where I rest, I noticed my sleep felt noticeably more continuous and settled. While I recognize that personal observations and correlations noticed in daily life are not formal laboratory studies, the consistency of what I observed in my own environment felt very real to me. ​Beyond just the raw strength of an individual signal, what stands out to me is the sheer number of overlapping broadcasting points we now live around. In any modern home or neighborhood, you are rarely dealing with a single transmitter; you have multiple wireless devices, mesh systems, and neighboring networks all transmitting simultaneously. As a citizen, I find it alarming that equipment is certified in isolation under standards that simply do not reflect the layered environments we actually inhabit. When multiple signals broadcast in the same physical space, wave dynamics like constructive interference can create complex, fluctuating peaks that single-device testing does not capture. ​My request to the Department is simply to take everyday citizen experiences and the reality of multi-device environments into account when evaluating how wireless technologies fit into our homes, especially in spaces meant for rest. It would be helpful to see more public guidance, balanced research into overlapping field interactions, and practical device options—such as straightforward ways to turn off wireless functions when not in use—so individuals can easily manage their home environments in the way that feels best for them.
