A new global study has raised alarms about the long-term consequences of giving children smartphones before they reach their teenage years. According to researchers, those who own smartphones before the age of 13 are more likely to struggle with severe mental health challenges well into young adulthood.
The study, published in the Journal of Human Development and Capabilities and drawing on data from more than 100,000 people worldwide, suggests that early smartphone use correlates with some of the most severe psychiatric outcomes. “Symptoms most strongly associated with earlier age of first smartphone ownership are not the typical measures of anxiety and depression,” the researchers reported, “but rather suicidal thoughts, aggression, detachment from reality, and hallucinations.”
To evaluate participants, the team relied on the Mind Health Quotient, or MHQ, a comprehensive assessment of emotional, social, cognitive, and physical well-being. The findings were stark. While those who first owned a smartphone at age 13 scored an average MHQ of 30, participants who had one at age 5 scored nearly 1, reflecting what the researchers called “a profound shift in mind health and wellbeing in early adulthood.”
Dr. Tara Thiagarajan, neuroscientist at Sapien Labs and lead author of the study, explained why the results are so concerning. “The adolescent and preadolescent years are critical for developing the mind’s foundation. Early smartphone ownership — and the social media access it often brings — appears to disrupt this process in lasting ways,” she said. She also emphasized that while the study shows correlation rather than direct causation, the consistency of the results across global regions should not be ignored.
The pathways by which smartphones influence mental health, the study found, are complex and often interconnected. Social media exposure played the largest role, but cyberbullying, poor family relationships, and disrupted sleep were also significant contributors. “These downstream effects illustrate how early and prolonged exposure to digital environments — before true agency develops — can compound into serious psychological harm over time,” the report noted.
Beyond the individual risks, the study highlights the societal implications of a generation growing up in what Thiagarajan described as an “always-on digital ecosystem.” According to her, the sheer accessibility of smartphones, paired with the lack of developmental readiness in children, creates an environment where younger users are uniquely vulnerable. “A child doesn’t yet have the tools to navigate the digital world safely,” she said. “We are giving them devices that can profoundly alter the trajectory of their lives before they have the capacity to manage them.”
The findings arrive amid growing international debate about youth smartphone use. Several U.S. states, including New York, have recently implemented restrictions on phone use in schools, while countries such as France, Italy, and the Netherlands have already enacted bans during classroom hours. These moves echo the study’s recommendations, which call for stricter enforcement of age restrictions, education on digital literacy, and reconsideration of how early children should be introduced to smartphones at all.
Still, the researchers caution that time is of the essence. “Childhood smartphone ownership,” they wrote, “is profoundly diminishing mind health and wellbeing in adulthood with deep consequences for individual agency and societal flourishing.” They argue that delaying policy interventions until definitive proof of causation is available may mean missing a critical opportunity to prevent widespread harm.
For parents, educators, and policymakers, the study provides not just a warning but a challenge: to reimagine the role of technology in childhood before its effects become irreversible. “We must begin to think about smartphones the way we do about alcohol or tobacco,” Thiagarajan said. “There is a collective responsibility to protect developing minds.”
Whether through regulation, education, or redesigned platforms, the study suggests one thing is clear — the conversation about how early is too early for a smartphone is no longer a matter of convenience, but of public health.
