Last year in college I got in to the really bad habit of sleeping like 5 hours every night, which to me is the bare minimum for me to be a functioning human. Now that I have tried to prioritize sleep, I find that I‘m more focused in class and more focused on finishing assignments concisely so I can hit the hay. Lowkey recommend, but I also don’t feel like 6 hours is that bad if that’s working out for you.
