Few topics generate more parental anxiety than screen time. Headlines swing between doom and dismissal. What does the research actually tell us?
The Nuanced Reality
The relationship between screens and child development isn't simple. Research suggests that how screens are used matters more than how much.
What the Evidence Shows
Potential Concerns
- Sleep disruption: Blue light and stimulating content before bed affects sleep quality
- Displacement: Screen time may replace physical activity, outdoor play, and face-to-face interaction
- Attention: Fast-paced content may affect attention span development in young children
- Social media: Linked to increased anxiety and depression in adolescents, particularly girls
Potential Benefits
- Educational content: High-quality programming can support learning
- Connection: Video calls with distant family members benefit children
- Digital literacy: Familiarity with technology is increasingly essential
Evidence-Based Guidelines
Australian guidelines recommend:
- Under 2 years: No screen time except video calling
- 2-5 years: Less than 1 hour per day of quality programming
- 5-17 years: No more than 2 hours of recreational screen time
Practical Strategies
- Create screen-free zones (bedrooms, dinner table)
- No screens 1 hour before bedtime
- Watch together and discuss content
- Model healthy screen habits yourself
Natural Remedies
Support healthy development alongside screen use:
- Outdoor time: Aim for at least 2 hours of outdoor play daily
- Eye health: Follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds)
- Physical activity: Active play helps counteract sedentary screen time
