That and does GP have a WiFi router a few meters from the bedroom, which they always unplug at night (disclaimer: I used to do that). And the clock next to the bed? Battery or socket?

You also cannot unplug all of your neighbours routers, TVs and other devices.

It is very easy to get paranoid about specific wireless technologies, it is almost impossible nowadays to avoid "electrosmog" or particularly wireless emitters entirely though.
