To improve our sleep hygiene we turn off the modem at night and we have nothing electrical in the bedroom (no phones in there and we switched to battery operated alarm clocks that don't emit constant light). I use flux on my computer but to be better you should go screen free for 1 hour before bed and dim the lights in the house at the same time. Try to go to bed earlier and rise earlier. Get outside in the daylight as early as possible- helps your circadain rhythm. You can also use block out curtains if you need them.
