Evidence: Why Reducing Screen Time Matters
Modern kids spend more than 4 hours per day on screens on average in the UK, with studies showing:
- Obesity risk increases with excessive sedentary screen time
- Sleep quality declines, especially with late-night device use
- Mental health can be affected, with increased anxiety and reduced self-esteem
- Physical activity levels drop, harming cardiovascular health
Evidence & Sources:
- The Royal College of Paediatrics and Child Health (RCPCH) recommends limiting recreational screen time and balancing it with physical activity.
- Public Health England has linked high screen time with obesity and poor mental health outcomes.
By encouraging kids to wear a fitness tracker, parents can make movement a daily goal—helping replace some passive screen time with active play.
