Screentime and Children’s Health

Overexposure to Screens is Impacting Our Children's Health

Protective policy is urgently needed.

Increasing Screentime 

Screen use in children and teens has escalated to unprecedented levels. In 2020, the American Academy of Child and Adolescent Psychiatry estimated that on average, children ages 8-12 in spend 4-6 hours a day watching or using screens, and teens spend up to 9 hours.

Social Media

A 2022 Pew Research Center survey found 35% of teens are “nearly constantly” on at least one of the top five social media platforms: YouTube, TikTok, Instagram, Snapchat, and Facebook. Yet research indicates that adolescents who spend more than 3 hours per day using social media may be at heightened risk for mental health problems,


Brain Changes

The largest long-term study of brain development and youth health in the U.S., the Adolescent Brain Cognitive Development (ABCD) Study, funded by NIH with  21 research sites across the country, analyzing brain scans of over 4,000 children who use electronic devices for seven hours or more each day have premature thinning of the brain cortex, the outer brain layer that processes information from the five physical senses (taste, touch, sight, smell and sound).

A 2022 Cincinnati Children’s hospital study also found differences in multiple brain regions associated with higher levels of digital media. These are just a few of the studies associating higher screen time with underdeveloped and altered brain development.



Science Finds Harm

Studies have found children’s excessive use of screens and digital media with a myriad of adverse effects including:

Children starting screens early in life (under two years old) is associated with speech and language delays.

Some scientists state the chronic sensory overstimulation of excessive screen time on brain development in youth will increase the risk of neurodegeneration and early onset dementia in in adulthood that will “result in widespread societal and economic distress” and “Preventative measures must be set in place immediately including investments and interventions in public education, social policy, laws, and healthcare.” 


Protective Policy

International Cell Phone in School Bans

According to the 2023 UN report one in seven countries ban the use of mobile phones in schools. 

Governments have banned cell phones in schools due to the impact on children’s learning range from England,  France, Netherlands, Finland and Israel, China, Australia, Ontario  and Greece to Ghana, Rwanda: and Uganda. 


USA School Cell Phone Bans

According to the National Center for Education Statistics, in 2020, cellphone bans were in place in 76% of U.S. schools. Public schools and districts from Pennsylvania, Maine, and New York  to  Missouri, to California, have instituted various types of cell phone and digital device bans, generally citing the cell phones ability to distract students from learning goals.


Parent Teacher Organizations

Parents are organizing to support healthier screen use initiatives. In Maryland for example, the Montgomery County Parent Teacher Association passed a resolution to combat excessive screen time and learning loss by passing the nation’s first parent-led Digital Balance Resolution.

School Cell Phone Bans Promote Learning

Research is finding school cell phone bans have a positive overall impact on academic attainment and student wellbeing. For example, research on two regions in Spain that banned phones in schools found significant reductions of bullying incidence as well as positive impacts on learning math and science. 

Banning smartphones in Norwegian middle schools significantly increased girls’ grade point average improved their math test scores and  increased their likelihood of attending an academic high school track. 

A 2020 survey of 210 principals published in the Journal of the American Medical Association showed that more than 90 percent supported restricting students’ cell phones in school and 86 percent believed devices in the classroom harmed academic performance.



“We pediatricians, child psychiatrists and youth psychiatrists are concerned about the increase in the load on children's and young people's brains, which is increased by the constant use of digital devices (including mobile phones). We recommend that during the school day children are guaranteed the right to learn, normal interaction, and safe growth and development without excessive use of digital devices.”
Statement of the Finnish Children's Medical Association, the Finnish Child Psychiatric Society and the Finnish Youth Psychiatric Society

Expert Recommendations to Minimize Screentime

U.S. Surgeon General Advisory

In late May, U.S. Surgeon General Vivek Murthy, MD, issued an advisory on social media and youth mental health, calling for technology companies to do better,  policymakers to strengthen safety rules, and researchers to focus on the issue. 


American Psychological Association

The American Psychological Association has issued a set of recommendations on social media use in youths that includes limiting harmful content and screening youth for “problematic social media use” that can impair daily life and risk serious psychological harms.  


American Academy of Pediatrics

The American Academy of Pediatrics discourages media use by children younger than 2 and recommends limiting older children’s screen time to no more than one or two hours a day.


  • American Academy of Pediatrics 2001 
  • American Academy of Pediatrics 2013
  • American Academy of Pediatrics 2016 Council  on  Communications  and Media,  Media and young minds. Pediatrics 


United Nations

Unesco, the United Nation’s education, science and culture agency released a report in 2023 entitled “Global education monitoring report, 2023: technology in education: a tool on whose terms?” stating that there was scientific evidence that excessive mobile phone use was linked to reduced educational performance and that high levels of screen time had a negative effect on children’s mental health and emotional stability.



Canadian Paediatric Society guidelines highlight four principles – minimizing, mitigating, mindful usage and modelling healthy use of screens – to move away from screen time limits, which can be a major source of stress for parents and children.


United Kingdom

The United Kingdom, Royal College of Paediatrics and Child Health has published guidelines to help parents manage children’s screen time through dialogue.


U.S States Laws to Address the Children's Health and Privacy Issues of Screens

Numerous states have passed laws to address the impacts of screens on children.

Resources for Parents on Screens

There are numerous resources for parents and caregivers
