A new study has revealed that lack of sleep in adolescents may result in their poor academic performances.
Researchers from Uppsala University demonstrated that reports of sleep disturbance and habitual short sleep duration (less than 7 hours per day) increased the risk of failure in school.
Author Christian Benedict said that another important finding of their study is that around 30 percent of the adolescents reported regular sleep problems.
Benedict added that similar observations have been made in other adolescent cohorts, indicating that sleep problems among adolescents have reached an epidemic level in our modern societies.
The study is published in the journal Sleep Medicine.
