Pediatric experts and health organizations generally recommend setting reasonable limits on daily recreational screen time for children and adolescents. Excessive screen use has been linked to various health issues in youth, while moderate use does not seem to be as concerning. Setting limits can help balance screen time with other important activities for growth and development.
The American Academy of Pediatrics (AAP) publishes guidelines on recommended daily screen time limits. For children ages 2 to 5 years old, the AAP recommends limiting screen use to just 1 hour per day of high-quality programming. This recommendation is meant to allow young children ample time to engage in creative, unstructured, and social play which is critically important at those early developmental stages. For children ages 6 and older, the AAP suggests limiting recreational screen time to no more than 2 hours per day. More lenient limits may be reasonable depending on the individual child and family situation, but going beyond 2 hours daily is not recommended on average.
The rationale behind the AAP’s limits involves concerns that excessive daily screen time can interfere with adequate sleep, physical activity, and other behaviors critical for health. Screen time has been linked to an increased risk of obesity, poor school performance, behavioral issues, and reduced physical, social, and emotional development in children when it displaces other healthy activities. The AAP acknowledges that moderate use of high-quality and engagement educational screen media may offer some developmental benefits when it does not take the place of real-world interaction, exploration, exercise and play.
Other major health organizations share similar views to the AAP. Canada’s 24-Hour Movement Guidelines for Children and Youth recommend limiting recreational screen time to just 1 hour per day for those 5 years and younger, and to no more than 2 hours per day aged 6 to 17 years. Public Health England also advises limiting recreational screen use to 2 hours or less daily for children and teenagers. The World Health Organization states that under 2 years of age, screen time (apart from video chatting) is not recommended at all, and for children ages 2 to 4, screen time should be no more than 1 hour – and less is better. For ages 5 to 17, the WHO suggests limiting screen time to 2 hours at most, with higher amounts proving detrimental to health, cognition, emotional and social development.
The scientific evidence behind the 2-hour daily limit for older children and adolescents involves multiple long-term studies. Research has consistently found correlations between excessive recreational screen time above 2 hours daily and increased risk of obesity, poorer diets, less physical fitness, worse sleep, lower academic achievement, greater social isolation, higher rates of depression and anxiety, and internet addiction issues. Studies also show that moderate viewing of 2 hours or less does not appear to negatively impact health or development compared to less screen time, indicating this is a reasonable daily upper limit for most youth.
Of course, not all screen time is equal in terms of effects on health and development. Educational and prosocial screen content that actively engages youth has been shown to potentially provide cognitive benefits when not overdone. Interacting online socially has also become developmentally important as technology progresses. The daily limits focus only on recreational screen time engaged in passively for entertainment like TV watching, social media scrolling, casual gaming and video app/streaming use. Schoolwork, homework, physical activity videos, educational apps and programming, video chatting with family and friends, and creative activities done with technology usually do not count towards recreational limits in recommendations.
Balancing screen guidelines with individual family needs requires adjustments. Some exceptions to the AAP’s overall limits are reasonable depending on a child’s temperament, natural activity levels, caregiver guidelines and household structure. For example, a very active child who only occasionally exceeds 2 hours on weekends may be fine, while an inactive child routinely surpassing 1-2 hours daily would be concerning and could use tighter limits. Caregivers knowing each child’s habits, skills and needs are in the best position to set customized limits flexibly within reason of what major health authorities advise for overall development. The guidelines are also meant to be adjusted as children age to reflect changing developmental stages.
The recommended daily limits on recreational screen time for children, tweens and teens aim to encourage healthy lifestyle habits, focus on behaviors key to growth, optimize brain development, and reduce health risks from overuse of digital devices and media. While moderate, quality use may offer benefits, exceeding the guidelines’ 1-2 hours for age groups has been consistently linked to issues due to screen time displacement of essential childhood activities. Caregivers can best apply the evidence-based limits flexibly based on each youth’s specific situation to promote well-being. The recommendations seek to promote balance with technology for healthy development in an increasingly digital world.
