My quality of sleep is much better with cell and wifi off. I live rural so there's less external sources too. It's significant enough that I turn it off every night as a habit. My issues with insomnia started back in 2000 when I first brought work into my small apartment.

Correlation is not causation. It could also be as simple as the light or vibrations from your phone at night disrupting your sleep. I've found blinking lights can make my sleep worse.

It's wifi too. I sleep with a mask and ear plugs. The very best sleep I get is with complete emf shielded and grounded clothing. The nights I don't do this are significantly worse. I'm tempted to get a sleep tracker but most are bluetooth. I've even tuned my router so it does less frequent heartbeats. If I ever build a house again I'd spend the money on shielding it entirely.

It's not wifi. There's literally no way for you to detect it and there are other, stronger radio signals constantly bombarding you.

I feel better if I completely turn off WiFi or Bluetooth. I can see I'm exposed to plenty of other signals by living in a city but it doesn't mean they're nothing. It just removes the added damage being done and it makes quite a difference to quality of life which would be hard to imagine for you.

My ammature theory (5Ghz wifi feels worse than 2.4Ghz wifi) also says higher frequency for short range signals does more harm, thus it's more sensitive to turn those off than being exposed to other lower frequency used outside.
