Electronic Screen Use and Sleep Duration and Timing in Adults

JAMA Network Open

Peer-Reviewed Publication

About The Study: Daily screen use was associated with later bedtimes and approximately 50 minutes less sleep each week in this study. Associations were greater among those with evening chronotypes, who are at risk for poor sleep due to social jetlag (i.e., misalignment between circadian rhythms and social commitments). These findings confirm disruptions to sleep from electronic screens are not limited to children and adolescents. Further work is needed to understand the best mechanisms for intervention.
