If you really can't stand it, you can tell your roommate directly that your biological clock is like this. You go to bed early every day because your roommate stays up too late, which affects you. Sometimes I get particularly upset because I can't sleep well. If you tell your roommate, I think as long as he doesn't want to make your's relationship particularly tense, your roommate will be more restrained in the future. If your roommate really doesn't care about your feelings, you can change yourself, that is, buy an eye mask and matching earplugs online, and then install a bed curtain where you sleep. These things are not expensive. After you install the bed curtain, if you want to sleep, pull it up. If you think your roommate is particularly noisy, put on an eye patch and earplugs. I think I can have a comfortable sleep.
Every dormitory will have its own contradictions, but sometimes it is necessary to discuss with roommates. If it really doesn't work, you can solve it yourself! But on the issue of sleeping, you can't return it!
