KIDSSocial media and smartphones harm children's mental health
Is this true? Make your call, then see what the science says.
Short answer: It depends. The evidence is mixed.
Studies link heavier social media use with more depression, anxiety and poor sleep in young people. But the links are mostly small and based on surveys, so they don't prove harm. How a child uses it seems to matter more than screen time alone.
AI-generated summary of the research cited · not reviewed by a medical professional · checked 13 October 2026 · How we checkWhat the research found
A 2024 systematic review with meta-analyses pooled 98 studies. It found small but significant links between social media use and both depression and anxiety. Problematic use was linked to depression, anxiety and sleep problems. A 2022 meta-analysis of 18 studies found moderate links between problematic use and depression, anxiety and stress.
A 2022 review of 25 earlier reviews found most called the links weak or inconsistent. A few called them substantial and harmful. A 2019 review of reviews found moderately strong evidence linking screen time with depressive symptoms, but only weak evidence for anxiety. A 2023 review found smartphone use on weekdays and social media use were linked to lower wellbeing, and social media to higher depression risk in girls.
A 2024 review said most findings are correlational and rely on self-report, so cause is still unproven. A 2026 narrative review said the evidence does not support a simple screen-time model. Risk appeared closer tied to harmful content, compulsive use, cyberbullying, poor sleep, social comparison and a child's own vulnerability.
What it doesn’t mean
- These studies show links, not proof that social media or phones cause mental health problems. Children who are already struggling may also use them more.
- Most research is on teenagers and young adults. The evidence is thinner for younger children, and the smartphone evidence is mostly about social media and screen time.
- See a GP or child health nurse if your child shows low mood, ongoing sleep problems, eating concerns, cyberbullying, or any talk of self-harm or suicide.
