Clinical Trial Summary

Sleep problems are common among adolescents which can have a variety of serious biological, emotional, cognitive and psychological consequences. Numerous studies have shown that adolescents who suffer from insufficient sleep and poor sleep quality experience decreased mental well-being which is a growing concern in modern societies. Effective interventions that enhance sleep quality among adolescents are lacking. One possible reason for sleep problems among adolescents is disturbance in the body's circadian rhythms. As light is known to be the main coordinating factor in circadian rhythms, light therapy is an auspicious method which aims to entrain the circadian rhythms, thereby enhancing sleep quality and well-being. Indeed, bright light therapy (BLT) has been shown to be a promising treatment to improve sleep and decrease depressive symptoms among different patient groups. However, BLT interventions among healthy adolescents are needed. Therefore, the current study will investigate whether BLT in classrooms of 16 year old students can improve their sleep quality and well-being. The results from the study can be important as it is the first one to examine whether light intensity in the classroom affects sleep and well-being among adolescents. Furthermore, if the hypothesis will be supported, a simple and relatively inexpensive method can be implemented to promote better sleep quality and thus have an extensive effect on adolescents' well-being. Aim 1 - Assess whether BLT will improve sleep quality of adolescents. Aim 2 - Assess whether BLT will decrease depressive symptoms in adolescents. Aim 3 - Assess whether BLT will improve mood in adolescents.
