If that’s the case, then turn it upside down so you don’t see the light from it, and put it aside.
Why Having an Evening Ritual is As Important As Having a Morning One
Srinivas Rao

One thing I do is turning my phone upside down and also put it on flight mode to avoid any notifications or cellular waves. Then I use an alarm clock waking me up at the best moment according to an analysis of my sleep (it’s a simple free app analyzing by the mic, not really scientific but it works pretty well).

Thank you for the good tips !
