You sir, are awesome! That's really interesting.
On Bluetooth, it surprised me how powerful the effect was until I turned it off on home and work laptops. Also, explained why my internet TV box kept bothering me even after I plugged it in with a cable.
Experience with Wifi also kind of fits. Worst effect was with home router, but was in very close proximity. Staying away from work routers though seems fairly easy.
Back in February, when i turned off loads of stuff, my colitis symptoms reduced, but a weird phenomena started. I got a large cyst under my tongue which seemed to be linked with using my electric toothbrush (stopped using, it reduced, started again, grew again, stopped and it went). So I think you may be right about EMFs in general. Interesting that this wasn't present earlier, like my immune system had switched to secondary target.
There's an EM field (which a magnetic field from a power line) that emanates into my bedroom from the power line adjoining my building. In the winter the EM reading is 13 milligauss, which is very high. I had to move my bed out of that bedroom when I found out, and my health got better. So did my sleep. In the summer time when people are using less electricity, the reading drops nearly to zero, so I can hang out in that bedroom more.
The best reader is the Cornet ED88T reader. You can read RF (from wireless routers and such), and EM from power lines.
You're not imagining things, this phenomenon is real and there are some countries that place limits on exposure, such as Germany, Sweden and Finland. The usually suspects coming to troll this thread by shaming us don't live your life and they don't experience what you experience. You have nothing to lose by making changes and seeing if it helps you feel better. I personally find bluetooth repellent and it affects my nervous system. The newer cell phones do too, so I don't talk on them with the phone against my head... I always use corded headphones.
