Overview
- Child development specialists say excessive and unstructured use of phones and tablets overstimulates brain systems that govern focus, self-control, decision-making and emotional regulation.
- Prolonged screen use, especially before bedtime, suppresses melatonin production and lowers sleep quality, which in turn undermines learning, memory and emotional control.
- Pediatric guidance stresses strict age limits: screens for children under 18 months should be limited to video calls and children aged two to five should get about one hour a day of high-quality, supervised content.
- Clinicians report that heavy device use fosters instant-gratification behaviours and dependence, with children often showing frustration or anxiety and throwing tantrums when devices are removed.
- Experts advise parents to structure use with fixed daily limits, screen-free meals and bedrooms, active outdoor play and parental modelling, and to treat well-designed educational apps as a complement rather than a replacement for real-world interaction.
