Type of Media Exposure Could Affect Children’s Sleep Habits
A new study reported in the journal Pediatrics indicates that earlier observational studies suggesting a link between certain types of media use and children's sleep problems indeed shows a causal relationship between the two. In a randomized controlled trial by Seattle Children's Research Institute among families with children ages 3-5, parents were encouraged to replace violent and age-inappropriate media content with high-quality educational content. The amount of media exposure or time of day children were viewing did not change.
Researchers measured changes in sleep habits over six months, according to lead author Michelle Garrison. Preschoolers in the study with sleep problems improved in both sleep and daytime tiredness over the 12-month study, and children without sleep problems were less likely to develop them.
