Decreased or disturbed sleep can result in poor performance of students in school.
Journal of Sleep Research
In a study, researchers from Norway (and their collaborators) worked on the affect of sleep duration and its pattern on the academic performance of adolescents in the age range of 16 years to 19 years. Researchers surveyed 7798 adolescents, of whom 53.5% were girls. In the survey, researchers asked them about sleep duration, its efficiency, sleep deficit, as well as bedtime differences between weekend and weekdays. School performance (grade point average (GPA)) of students was taken from official registers in schools.
Researchers found that students with short sleep duration and sleep deficit have more chances of getting poor grades. They also reported that weekday bedtimes were significantly related to performance of students, i.e. adolescents with the habit of going to bed between 22:00 and 23:00 hours got best GPAs. Students’ academic performance also declined because of delayed sleep schedule during weekends.
“The demonstrated relationship between sleep problems and poor academic performance suggests that careful assessment of sleep is warranted when adolescents are underperforming at school,” researchers wrote in the paper.
