A comprehensive review in The Lancet highlights the serious health risks posed by digital platforms designed to capture attention and harvest data, advocating for urgent global regulation prioritising children and adolescents.
A new analysis published in The Lancet argues that children and teenagers are being exposed to digital systems built to hold attention and harvest data, and that the resulting health risks are serious enough to justify immediate policy action. The review, part of a wider three-paper series, says the issue is not simply the amount of time young people spend online, but the way platforms are designed, marketed and governed. It calls for public health to be placed at the centre of digital regulation, with children and adolescents treated as an urgent policy priority.
The series draws on an umbrella review covering nine million people under the age of 25 across 121 published reviews. According to the authors, problematic digital media use – meaning addiction-like patterns rather than screen time alone – is consistently linked with poorer mental health, sleep problems and less physical activity. The evidence also points to some possible benefits, including associations between moderate use and greater wellbeing, as well as links between active video gaming and healthier lifestyles. But the researchers say the overall certainty of the evidence remains low and cannot prove cause and effect. That caution is echoed by recent systematic reviews, which have found that problematic social media use is associated with depression, anxiety and poorer wellbeing, while broader social media use shows only weak links with those outcomes.
Sleep appears to be one of the clearest areas of concern. A separate updated review on electronic media use and sleep found that heavier use is significantly associated with poorer sleep quality, while another systematic review of adolescents found that problematic device use can damage both sleep quality and duration. Research published in the Journal of Sleep Research also suggests that sleep may partly explain the connection between device use and adolescent mental health. Other reviews have reported similar patterns, including shorter sleep duration, longer time taken to fall asleep and more sleep disturbance among young people with problematic social networking use. Taken together, the studies suggest that sleep may be one of the main pathways through which digital habits affect health.
The Lancet authors say the answer is not a single fix such as age limits, but a broader strategy that would require technology companies to test new products for harm, share relevant data with independent researchers and face stronger oversight at national and international level. They also argue that firms have too often used familiar tactics to slow regulation, including casting public health measures as threats to freedom. The series proposes a global governance framework, potentially backed by the World Health Organisation, to prevent weak rules in one country from undermining progress elsewhere. Its message is clear: waiting for perfect evidence could mean waiting too long.
