Ages 8–10
Screen time and online safety for ages 8–10
Friends’ devices change everything. Even without their own phone, kids this age are usually inside group chats.
Screen time — what experts recommend
Protect sleep, movement, schoolwork and offline relationships. Choose content and agree manageable boundaries together. A time target alone cannot establish whether use is healthy or harmful.
UK context: Separate family rules from formal guidance. Canada’s linked guideline suggests no more than 2 hours of recreational screen time for ages 5–17; this is not a UK rule or a quota specifically for social media. The UK activity guidance and international sleep advice address other parts of the day.
Total time across phone, tablet, TV, console and computer combined (school work usually excluded).
Evidence and practical considerations
- Studies of school-aged children and adolescents often associate screen use with shorter or later sleep; there is no single verified “minutes lost per extra hour” estimate used here.
- Discuss unwanted contact and bullying in games and chats. A child’s experience matters more than assuming every group is harmful.
- Notice persistent changes in sleep, schoolwork or relationships and ask what is happening; one behaviour alone does not diagnose problematic gaming.
