A study published in
Pediatrics found an association between the use of digital devices before
bedtime and inadequate and disrupted sleep in children and adolescents. This study by Pediatrics summarizes the
literature on electronic media and sleep and provides research recommendations.
This report finds that underlying mechanisms of these associations
likely include the following: (1) time displacement (for example, time spent on
screens replaces time spent sleeping and other activities); (2) psychological
stimulation based on media content; and (3) the effects of light emitted from
devices on circadian timing, sleep physiology, and alertness. Further
experimental and observational research is needed to elucidate how the digital
revolution is altering sleep and circadian rhythms across development (infancy
to adulthood) as pathways to poor health, learning, and safety outcomes (such
as obesity, depression, and risk-taking).
