Experts Warn Parents About Excessive Screen Time as Children Spend More Hours on Smartphones and Tablets

New Delhi | September 2026: Smartphones, tablets and digital devices have become a normal part of childhood. From educational videos and online classes to cartoons and games, children between the ages of 3 and 12 are increasingly exposed to screens every day.

But experts say the important question is not simply “Should children use mobile phones?” — it is “How much, what type and under what supervision?”

Research and guidance from organizations including the World Health Organization (WHO) and the American Academy of Pediatrics (AAP) highlight concerns about excessive sedentary screen use, particularly when it replaces physical activity, adequate sleep, reading, play and meaningful interaction with parents and other children.

Why Excessive Mobile Use Can Be a Concern

1. Less Physical Activity

When children spend long periods sitting with a phone or tablet, they may have less time for running, outdoor games, sports and active play.

WHO recommends that young children have substantial opportunities for physical activity throughout the day. For children aged 3–4, the WHO recommends at least 180 minutes of physical activity per day, including at least 60 minutes of moderate-to-vigorous activity.

For school-aged children, regular physical activity is also important for healthy development.

2. Sleep Can Be Affected

Using screens late in the evening can interfere with healthy bedtime routines. Poor sleep can affect children’s concentration, mood, behaviour and school performance.

The CDC notes that children aged 6–12 years generally need 9–12 hours of sleep per 24 hours, and inadequate sleep is associated with problems including attention and behaviour difficulties.

Parents can help by creating a screen-free bedtime routine and keeping phones and other devices away from children’s sleeping areas.

3. Less Time for Reading and Learning

Not all screen time is equal.

An educational activity in which a parent and child learn together is very different from several hours of passive video watching or gaming.

The American Academy of Pediatrics emphasizes that media use should be balanced with children’s developmental, educational, social and physical needs.

Children also need time away from screens for books, drawing, puzzles, imaginative play and hands-on learning.

4. Reduced Family Interaction

A phone can sometimes become an easy way to keep a child occupied. However, excessive device use may reduce opportunities for conversations, storytelling and face-to-face interaction.

WHO specifically encourages activities such as reading, storytelling and singing with caregivers instead of sedentary screen activities for young children.

These simple interactions help children communicate, ask questions and learn through real-world experiences.

5. Exposure to Inappropriate or Unsafe Content

Children can encounter content that is inappropriate for their age, including frightening material, misleading information, advertisements and unsafe online interactions.

The AAP identifies exposure to inaccurate, inappropriate or unsafe content and contacts among potential risks associated with media use.

For this reason, parents should not only monitor how long a child uses a device, but also what the child is watching and doing online.

What About Children Aged 3–5?

The WHO recommends that children aged 3–4 years have no more than one hour of sedentary screen time per day, with less being better.

The AAP similarly recommends limiting media use for children aged 2–5 years to about one hour or less per day of high-quality programming, ideally with parents helping children understand what they are watching.

For preschool children, parents can prioritize:

• Storybooks
• Drawing and colouring
• Puzzles
• Outdoor play
• Music and singing
• Building blocks
• Pretend play
• Parent-child conversations

What About Children Aged 6–12?

For older children, there is no single universal number of hours that automatically determines whether screen use is healthy.

The AAP’s current approach emphasizes an individualized Family Media Plan for children aged 6 and older. Parents are encouraged to make sure screen use does not crowd out sleep, physical activity, schoolwork, family time and other important activities.

Parents can establish simple household rules such as:

No phones during meals.

No screens during homework unless required.

No devices in the bedroom at bedtime.

Daily outdoor or physical activity.

Age-appropriate content only.

Parents regularly check what children are watching and playing.

Is All Screen Time Bad?

No.

This is an important distinction.

A child watching an educational lesson, talking to grandparents through a video call, creating digital artwork or using an age-appropriate learning application is not necessarily equivalent to spending hours passively watching short videos.

The AAP notes that different forms of screen use can have very different effects and that media can also provide opportunities for learning, creativity, communication and social connection.

The goal should therefore not be “zero technology.”

The goal should be healthy technology habits.

A Simple Rule for Parents

Instead of asking only:

“How many hours is my child using the phone?”

Parents can ask five questions:

1. What is my child watching?

2. Is it appropriate for their age?

3. Is the screen replacing sleep or physical activity?

4. Is it replacing reading, playing or family interaction?

5. Can my child comfortably stop using the device when asked?

These questions can provide a more useful picture of a child’s digital habits than screen time alone.

The Bottom Line

Mobile phones and tablets are not automatically harmful to children. They can be valuable tools for education, creativity and communication when used appropriately.

The concern begins when excessive screen use starts replacing the activities children need for healthy development — sleep, physical activity, play, reading, social interaction and family time.

For parents of children aged 3–12, the message from health experts is increasingly about balance, boundaries, supervision and age-appropriate content rather than simply banning technology.

A healthy childhood does not need to be completely screen-free.

But it should never become screen-only.
