A sweeping global study has found that children who receive smartphones before the age of 13 face significantly higher risks of poor mental health outcomes later in life. The research, which surveyed nearly 2 million people across more than 160 countries, links early smartphone ownership to increased rates of depression, suicidal thoughts, aggression, and low self-worth, especially among girls. Experts warn that excessive screen time and early exposure to social media can disrupt sleep, emotional regulation, and social development. The findings have prompted calls from scientists and health professionals to delay smartphone access for children and to implement stricter policies around digital device use. Parents are being urged to reconsider when and how their children are introduced to smartphones to protect their long-term well-being.
