For screen time, the guidelines recommend: no screen time for children younger than two years. no more than one hour per day for children aged 2–5 years. no more than two hours of sedentary recreational screen time per day for children and young people aged 5–17 years (not including schoolwork).
Under 2 years old: Zero screen time, except for video chatting with family or friends. 2-5 years old: No more than one hour per day co-viewing with a parent or sibling. 5-17 years old: Generally no more than two hours per day, except for homework.
Added together, all types of screen time can total 5 to 7 hours a day. Too much screen time can: Make it hard for your child to sleep at night. Raise your child's risk for attention problems, anxiety, and depression.
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.
What's a healthy amount of screen time for adults? Experts say adults should limit screen time outside of work to less than two hours per day. Any time beyond that which you would typically spend on screens should instead be spent participating in physical activity.
Encourage unplugged, unstructured playtime. Create tech-free zones or times, such as during mealtime or one night a week. Discourage use of media entertainment during homework. Set and enforce daily or weekly screen time limits and curfews, such as no exposure to devices or screens one hour before bedtime.
Key findings
At 4–5 years old, children average more than two hours screen time per week-day. By 12–13 years old, this increases to more than three hours average per week-day and almost four hours per weekend day. This means that up to 30% of a child's waking time is spent in front of a screen.
Excessive screen time may inhibit a child's ability to observe and experience the typical everyday activities they need to engage with in order to learn about the world, leading to a kind of “tunnel vision,” which can be detrimental to overall development.
Early screen exposure has been associated with lower cognitive abilities and academic performance in later years. Language development is also affected by screen time, as it diminishes the quantity and quality of interactions between children and caregivers.
Some child development experts confirmed that the show is hyper-stimulating and can cause addiction as the result. Jerrica Sannes, an expert in early childhood, development and education, claimed the show was not only overstimulating, it's also likely to cause behavioral problems and attention disorders.
Screen time induces stress reactions.
Both acute stress (fight-or-flight) and chronic stress produce changes in brain chemistry and hormones that can increase irritability. Indeed, cortisol, the chronic stress hormone, seems to be both a cause and an effect of depression—creating a vicious cycle.
In multiple studies, excessive screen time has been linked to school problems, anger, aggression, frustration, depression and other emotional problems. Over-stimulation causes kids to have poor focus and depletes their mental energy, which often leads to explosive behavior.
Passive screen time is more consumptive. Playing video games, using mindless apps on a phone or tablet, or watching TV (Swinson, 2018). Resnick (2018a) describes passive screen time as having an anti-social impact. We sit and get sucked into our screen without interacting with those around us.
When it's restricted your child is more likely to binge, hyper-focus, get anxious or sneak time when you're not watching. They can never fully relax and enjoy their play or viewing because they will be worried that it will be taken away.
But too much can take away from other activities, such as sleeping, exercising, playing with friends, and doing homework. Studies show that kids who watch too much TV are more likely to be overweight — and, depending on the content of what they see, more aggressive.
“There is also evidence of a correlation between media use and the severity of ADHD symptoms. Screens may not cause ADHD, but they may play some role — depending on what limits are placed on them and how a child or teen is using them — in exacerbating the way that ADHD symptoms are expressed.”
They found that outdoor play time could reduce the harmful effects of screen time on daily living skills by 20 percent. Further, the researchers found that socialization skills improved among four-year-olds who spent more time outside at the age of two years and eight months.
Though screen time doesn't cause ADHD, some studies have suggested that children with ADHD may be at increased risk of developing a screen addiction. While parents of children with ADHD can try to be aware of their kid's screen time, most children's screen time falls short of addiction, according to Lightfoot.
The American Academy of Pediatrics used to recommend less than two hours for ages 5 and up. Now they are moving away from giving specific hours, because the reality is that most kids spend far more than two hours a day on screens, and not all screen time is equal.
Average screen time for kids ages 2 to 4 – 2 to 2.5 hours a day. Average screen time for kids ages 5 to 8 – Over 3 hours a day. Average screen time for tweens ages 8 to 12 – Almost 5 hours a day. Average screen time for teens – Almost 7.5 hours a day.
The AAP discourages screen use for children younger than 18 to 24 months, and recommends a limit of an hour a day for children between the ages of 2 and 5, and two hours of non-schoolwork use for school-age children between 6 and 17. However, it can be difficult for parents to gauge how to manage screen time.

Too much screen time can lead to obesity, sleep problems, chronic neck and back problems, depression, anxiety and lower test scores in children. Children should limit screen time to 1 to 2 hours per day. Adults should also try to limit screen time outside of work hours.
Too much screen time can also harm children's' and teens' mental health. A very large 2018 study found that teens who used screens for 7 or more hours per day were twice as likely to be diagnosed with depression or anxiety, compared with those who used screens for less than one hour.
