Factors relating to poor sleep have been found to have a significant impact on school performance. The major cause is the pressure that students feel when having to juggle academics, extracurricular activities, family time, and a social life. The buildup of stress can lead to sleepless nights, which can be detrimental to their schoolwork. Lack of sleep makes it harder for children to retain information. And it becomes an even bigger issue when they have to take exams.
