Health care providers can help families understand that TV watching and screen time habits can have significant effects on their children’s development, health, and social skills.

- Various injuries (hand, wrist, forearm, and elbow) have been associated with extended computer and video game use (more than 20 hours per week). (Source: Child Trends 2009-29)
- Overexposure and/or unsupervised use of the internet or television can lead to social and emotional problems and risky behaviors in children, such as: ADD/ADHD, bullying and violent behavior, and sleep disorders. (Source: AAP, Pediatrics, 2001)
