EMF waves from my WiFi and Phone affect my sleep cycle and a lot of other things too :-0((

Most routers let you adjust the level of 'signal strength'. Worth playing around with.
Or go wired Ethernet and shut Wi-Fi off entirely.

It's not only a problem of my signal strength @Harka I made a mistake when I commented this post. I have fiber and the waves don't enter my rooms so much and I also turn off my router and WiFi at night when I go to bed, but unfortunately, my neighbours, who live above my flat don't do the same as I do, neither do and the neighbours living next door to me and the walls are not very resistant to such effects, so waves can penetrate through the walls into my flat at night, so that may be the cause, plus the use of my phone. If I use it until late at night before going to sleep that may also affect my sleep I imagine. It's rather complicated to explain and learn how to live with such technology.
