Overview
- Analysis of over 100,000 18- to 24-year-olds shows those who got smartphones before age 13 report higher rates of suicidal ideation, aggression, detachment from reality, emotional dysregulation and low self-worth.
- Early ownership frequently coincided with under-age social media use, contributing to cyberbullying, sleep disruption and strained family relationships by adulthood.
- The link between early smartphone access and poorer mental health was consistent across more than 160 countries, cultures and languages.
- Lead researcher Dr. Tara Thiagarajan and other experts urge under-13 smartphone restrictions, mandatory digital literacy education and stronger tech company accountability.
- Despite relying on self-reported data and lacking proof of direct causation, researchers liken the precautionary measures to alcohol and tobacco regulations to protect developing minds.
