I am a practicing Internal Medicine physician with roughly 10 years' experience treating adult patients using "Integrative" strategies, ie, specific biologically precise strategies which fundamentally address the root causes of chronic illness. I also personally suffer from chronic illness, thus providing the opportunity to experience the results of many, if not all, of the strategies I employ. 
Roughly 10 years ago, I became aware of the possibility that I was personally being affected by wireless (ie, RF/EMF) radiation exposure in my own household. Specifically, it was suggested to me by my health coach that my difficulty sleeping (for the previous 5-6 years) might be due to RF/EMF exposure, at that time cell phones not powered off at night plus WiFi router exposure, both at my office as well as at night in my home. I somewhat skeptically agreed to a trial of powering off cell phones and WiFi router at night, and my sleep immediately improved dramatically enough for me to conclude clinically that the improvement was very likely due to this removal of RF/EMF exposure. We eventually permanently eliminated the WiFi router and hard-wired our house with internet cabling, along with powering off our cell phones at night. I also keep my personal cell phone on airplane mode continuously during the day, establishing connectivity only to receive and read texts. I don’t use my cell phone for calls at all. This has resulted in our home becoming a relatively “safe haven” for me from an RF/EMF perspective.
In fact, I use only a landline in my home office to make calls, doing most of my clinical work from home, and go to my medical office only to see patients, maybe an hour or two a day. My medical office, even though also hard-wired to minimize RF/EMF, has EMF levels (ie, density) from 700 to 1500 microwatts per meter squared, presumably from wireless devices in adjoining tenants’ offices and perhaps from nearby cell towers and I typically experience difficulty sleeping if I’ve spent three or more hours in my office. I have done extensive RF/EMF measurements throughout various parts of my city, most of which have EMF density levels of at least  500, and often up to 2500 microwatts per meter squared. When I have prolonged exposure to an environment with these higher densities, such as my place of worship which reads 2000 to 3000 microwatts per meter squared, I always experience increased difficulty sleeping, along with increased daytime fatigue for the next two days. 
Perhaps an experience I had very early in the process of discovering my own reactions to wireless radiation will be helpful.
I was attending a neighborhood meeting located on the top floor of a tall apartment building, roughly 20 stories tall. As participants got seated, the middle-aged woman next to me said that she was sensitive to RF/EMF, and that on the roof of this building (right above us) were situated an array of wireless antennae. She then proceeded to pull out an EMF meter to show me the readings, which were very high. In fact, she told me that she would need to leave the meeting before its conclusion to avoid excessive EMF exposure, which she did after thirty or forty minutes.
I had never knowingly had this level of exposure, and was feeling no particular symptoms, so I attended the remainder of the two-hour meeting. Within a day or so, I felt exhausted, and it took another 3-4 days to fully recover.
Surprisingly to me at the time, I began to notice similar symptoms whenever I was again exposed to excessive RF/EMF radiation. Clinically, it was behaving in a way familiar to any practicing physician; namely, now that my system had sustained injury, the injured system was more susceptible to that same type of injury.

What follows is an explanation of how this process occurs on a microscopic level, with both a link to full explanation, as well as sound byte-style quick summary:

•	Exposure to microwave EMFs, like cellphones, causes massive mitochondrial dysfunction due to damage done by free radicals from peroxynitrite that also cause single and double stranded breaks in your DNA
Excessive free radicals triggered by low-frequency microwave exposure from cellphones and Wi-Fi networks have been linked to chronic diseases such as cardiac arrhythmias, anxiety, depression, autism, Alzheimer’s and infertility
Excessive calcium signaling produced by EMF exposures also has important roles in producing pathophysiological effects of EMFs including each of the effects listed above

In summary, exposure to nearly ubiquitous RF/EMF radiation has nearly confined me to my own home, essentially imposing upon me excessive fatigue whenever I venture out to the community at large.
