It's a lifestyle choice - if you go to sleep at 11pm of course 8am classess will make you detest them will have no concentration. Especially true if you use your phone up until you fall asleep. I was a student until recently and can say most of the burden is unfortunately on us. From my experience students lock themself in their room listen to music/play games/scroll social media until midnight. Instead of building a community where hanging out/studying with other students until lets say 8pm and then going to sleep would be the best for most students. When hanging out in groups you are filling our your need for socializing and more likely to regulate each other. When everyone is siloed in their own room you are more likely to see extreme disregulation like going to sleep at 1/2am on most days.
Not everyone is a morning person I will concede that much. But being a morning person, there is NOTHING that makes a day more cursed for me than waking up at 9AM when the sun is already up and most people are out and about.
In my opinion, what students (and all of us) need is universal digital hygene. A set of guidelines where we would finally be able to follow if we ever fall into disregulation. Not advocating for China style timeout lockdowns of your netflix/games, just a general set of guidelines so that if you stay up until 23pm /1am - it's your responsibility. Just like it's your responsibility to not regulate every other aspect of your life. You should be encouraged to be an adult.
