According to a survey, we know most middle school students sleep less than 7 hours' each night, much less than required.
First of all, the students have too much homework. Second, schools and parents pay less attention to their sleep. Another important reason is that many students play with their cell phones or iPads before sleeping. This is one of the main reasons for bad sleep. Other reasons include stress and bad moods.
So we must take some ways to stop this. First, less homework should be given to the students by teachers and parents. Second, students need to keep away from digital devices for at least an hour before sleep .Last, more attention should be paid to their health.
