I imagine, like most things, it's on a spectrum. No screen (for the first hour of the day) is probably better than Duolingo, which is better than doomscrolling. I also imagine it varies between people. I can get overstimulated by screen use, so I feel much better if I don't use it for the first and last hours of the day, but I'm not always good at keeping to that rule!
