Children and teens are spending significant time with screens each day, averaging around 4 hours for 3-5 year olds, 6 hours for 8-12 year olds, and 9 hours for 13-18 year olds. Screens can provide educational benefits when used properly, such as improving literacy and attention, but excessive unstructured use is linked to negative effects including poor sleep, obesity, behavioral issues, and possibly autism symptoms or addiction for some. Parents need to lead by example with their own screen use, set clear guidelines for children around screen time and content, and promote family screen-free times and open communication.
