Tips for Healthy Screen Habits
No screens before bed
Switch off all devices at least 1 hour before bedtime. Blue light disrupts sleep hormones.
Screen-free mealtimes
Family mealtimes without devices encourage conversation and mindful eating.
Outdoor time first
Make sure physical activity and outdoor play happen before screen time begins each day.
Set a family schedule
Agreed daily screen time windows work better than ad-hoc restrictions and reduce conflict.
Watch together
Co-viewing and discussing content helps younger children process what they see.
Screen-free zones
Keep bedrooms and bathrooms as screen-free zones for all family members.
Quality over quantity
Educational apps and creativity tools are far more beneficial than passive viewing.
Use parental controls
Most devices have built-in screen time controls. Set daily limits so the device enforces the rules.

Frequently Asked Questions
Children aged 2–5 should have no more than 1 hour of screen time per day, according to both the NHS and the American Academy of Pediatrics (AAP). This should ideally be high-quality, educational content watched together with a parent or caregiver.
No. The recommended daily limits refer to recreational screen time — entertainment, social media, gaming, and passive TV watching. Educational use such as homework, school video calls, and reading apps is counted separately. The key is balance and intentional use.
Yes, significantly. Screens emit blue light which suppresses melatonin — the hormone that signals it's time to sleep. This makes it harder for children (and adults) to fall asleep and reduces overall sleep quality. Both the NHS and AAP recommend a screen-free period of at least 1 hour before bedtime for all children.
Warning signs include: irritability or tantrums when devices are taken away, difficulty concentrating on non-screen activities, sleep problems, headaches or eye strain, reduced interest in hobbies and outdoor play, neglecting homework or social time, and using screens to cope with boredom or negative emotions.
No. Content quality matters enormously. A child using an educational app, video calling grandparents, or creating digital art is engaged in very different screen time to passive social media scrolling or watching unrelated YouTube videos. Guidelines focus on limiting passive, recreational screen time rather than all digital activity.
The most effective approach is to set agreed family rules (ideally with your child's input for older children), use the built-in Screen Time tools on Apple devices or Digital Wellbeing on Android, and give 5–10 minute warnings before time runs out. Consistency is key — the device enforcing the limit (not you) removes the argument.
For teens aged 13–17, neither the NHS nor the AAP sets a specific hour limit. Instead, they recommend focusing on the quality and impact of screen use: ensuring it doesn't replace sleep, physical activity, homework, or face-to-face socializing. A practical target many families use is 2–3 hours of recreational screen time on school days.
