text: Students might want to catch up on sleep that they missed the night before or relax after a long day of school. This is because it would help students brains refresh or reboot by giving them a longer break. Some students also stay up too late working on long/short projects and homework that their teacher assigned so they don't get enough sleep that day. Because they don't get enough sleep, they become tired, which affects their moods during the school day and causes them to not only feel tired, but depressed and angry. Sleep really affects students ability to focus and finish their work on time but if they have to do an extracurricular activity after school, then that will make them more tired and will take away the extra time they get to catch up on sleep and relax.
