Screens and Children's Sleep: What the Evidence Says

What does the research show about screens and sleep?

A large review of studies found that children and teens who had access to or used a portable screen-based device at bedtime slept fewer hours, had poorer sleep quality, and were sleepier during the day 1Ref 1Carter B, Rees P, Hale L, Bhattacharjee D, Paradkar MS (2016).Association Between Portable Screen-Based Media Device Access or Use and Sleep Outcomes: A Systematic Review and Meta-analysis.Bedtime access to and use of portable screen devices is associated with shorter sleep duration, poorer sleep quality, and daytime sleepiness in children.. A separate systematic review of 67 studies reported a harmful link between screen time and sleep in about 90% of them, most often shorter sleep and a later bedtime 2Ref 2Hale L, Guan S (2015).Screen Time and Sleep Among School-Aged Children and Adolescents: A Systematic Literature Review.A systematic review of 67 studies found screen time adversely associated with sleep (shorter duration, delayed timing) in ~90% of studies.. Importantly, simply having a device in the room mattered, even when a child wasn't actively using it 1Ref 1Carter B, Rees P, Hale L, Bhattacharjee D, Paradkar MS (2016).Association Between Portable Screen-Based Media Device Access or Use and Sleep Outcomes: A Systematic Review and Meta-analysis.Bedtime access to and use of portable screen devices is associated with shorter sleep duration, poorer sleep quality, and daytime sleepiness in children. — a reminder that the bedroom environment is part of the picture, not just the minutes on a screen.

Why do screens push bedtime later?

A few things tend to stack up at once. Engaging content — games, videos, social feeds — is designed to hold attention, so 'just one more' quietly displaces the time a child would otherwise be winding down or asleep 3Ref 3Munzer T, Parga-Belinkie J, Milkovich LM, Tomopoulos S, Ajumobi T, Cross C, Gerwin R, Madigan S; Council on Communications and Media, American Academy of Pediatrics (2025).Digital Ecosystems, Children, and Adolescents: Policy Statement.Engagement-driven digital design encourages prolonged use that displaces sleep and other activities.. Late notifications and bright screens can also delay the natural drift toward sleep. The result is less total sleep, which matters because school-aged children generally need 9–12 hours and teens need 8–10 hours per night on a regular basis 4Ref 4Paruthi S, Brooks LJ, D'Ambrosio C, Hall WA, Kotagal S, Lloyd RM, Malow BA, Maski K, Nichols C, Quan SF, Rosen CL, Troester MM, Wise MS (2016).Recommended Amount of Sleep for Pediatric Populations: A Consensus Statement of the American Academy of Sleep Medicine.Children 6–12y need 9–12h and teens 13–18y need 8–10h per 24h on a regular basis.. Falling short is linked to harder mornings, more trouble with attention and mood, and other health effects over time 5Ref 5Paruthi S, Brooks LJ, D'Ambrosio C, Hall WA, Kotagal S, Lloyd RM, Malow BA, Maski K, Nichols C, Quan SF, Rosen CL, Troester MM, Wise MS (2016).Consensus Statement of the American Academy of Sleep Medicine on the Recommended Amount of Sleep for Healthy Children: Methodology and Discussion.Meeting recommended sleep is associated with better attention, behavior, learning, and emotional regulation..

What practical steps tend to help?

• Keep devices out of the bedroom overnight. A shared charging spot outside bedrooms removes the bedtime pull and the middle-of-the-night check 6Ref 6American Academy of Child and Adolescent Psychiatry (AACAP) (2020).Sleep Problems (Facts for Families No. 34).Guidance on healthy routines: no screens/electronics 1–2 hours before bed, no devices in the bedroom, consistent bedtimes..
• Set a screen-free window before bed. Many clinicians suggest no screens for the 1–2 hours before sleep 6Ref 6American Academy of Child and Adolescent Psychiatry (AACAP) (2020).Sleep Problems (Facts for Families No. 34).Guidance on healthy routines: no screens/electronics 1–2 hours before bed, no devices in the bedroom, consistent bedtimes..
• Make bedtime predictable. A consistent bedtime and a calm wind-down (bath, books, quiet talk) signal the body it's time to sleep 6Ref 6American Academy of Child and Adolescent Psychiatry (AACAP) (2020).Sleep Problems (Facts for Families No. 34).Guidance on healthy routines: no screens/electronics 1–2 hours before bed, no devices in the bedroom, consistent bedtimes..
• Make a Family Media Use Plan together. The American Academy of Pediatrics suggests families set screen-free zones like meals and the hour before bed, and protect time for sleep and play 7Ref 7American Academy of Pediatrics, HealthyChildren.org (2023).How to Make a Family Media Plan (AAP Family Media Use Plan).AAP recommends a Family Media Use Plan with screen-free zones including before bed and protected time for sleep.. Building it together — rather than handing down a rule — tends to make it stick.

When your child's sleep needs a clinician

Most screen-and-sleep issues respond to routine changes at home. But it's worth talking with your child's pediatrician if sleep stays disrupted after a few weeks of consistent limits, if your child snores loudly or seems to stop breathing in sleep, or if daytime tiredness is affecting school, mood, or behavior. A clinician can use a validated parent questionnaire like the Children's Sleep Habits Questionnaire to map exactly where the trouble is 8Ref 8Owens JA, Spirito A, McGuinn M (2000).The Children's Sleep Habits Questionnaire (CSHQ): Psychometric Properties of a Survey Instrument for School-Aged Children.Validated parent-report instrument for identifying behavioral and medical sleep problems in school-aged children., rule out medical causes such as a breathing problem, and help you build a realistic plan — including coordinating with the school if mornings or attention are suffering. They can also help sort out whether what looks like a 'screen problem' is partly anxiety or another treatable cause, since sleep and mood feed each other in both directions 9Ref 9Alvaro PK, Roberts RM, Harris JK (2013).A Systematic Review Assessing Bidirectionality between Sleep Disturbances, Anxiety, and Depression.Poor sleep is bidirectionally related to anxiety and depression..
