A 16-year-old boy’s attempt at self-harm prompted a British doctor to examine the impact of excessive screen time on adolescent mental health, leading to a call for stricter regulations on technology utilize, including a potential ban on social media for individuals under 18.
Dr. Rangan Chatterjee, a former general practitioner and host of the popular podcast “Perceive Better, Live More,” detailed the case in an interview with The Guardian on February 16, 2026. Initially, the hospital physician treating the teenager recommended antidepressants. However, Chatterjee sought to understand the underlying causes, discovering the boy spent a significant amount of time using digital devices, particularly in the evenings.
Chatterjee advised the boy and his mother to implement a “digital curfew,” starting with an hour before bedtime and gradually increasing the screen-free period over six weeks. Within two months, the boy’s condition improved to the point where he no longer required regular consultations. Several months later, his mother reported a complete transformation, noting he was re-engaging with friends and exploring new activities.
“We are in the middle of an experiment that no one consciously signed up to,” Chatterjee said, describing the widespread adoption of digital technology and its effects on a generation. He argues that excessive screen time is “the most urgent public health issue” facing society today, citing its links to anxiety, depression, sleep disturbances, and even physical ailments like neck and shoulder pain.
Chatterjee’s concerns extend to the potential for exposure to inappropriate content. He referenced data indicating that 10 percent of nine-year-olds and 27 percent of eleven-year-olds have encountered pornography. He also highlighted research suggesting a 21 percent increased risk of myopia with each additional hour of screen time, and a 54 percent increased risk of worsening myopia in those already nearsighted.
The doctor believes that adolescents lack the neurological maturity to regulate their own social media use, as the parts of the brain responsible for decision-making are not fully developed until around age 25. He also expressed skepticism about the ability of technology companies to self-regulate, given their business models rely on maximizing user engagement.
As a parent of two teenagers, Chatterjee allows his children to have mobile phones but has disabled most apps and internet browsers. He enforces a strict “screen-off” policy at least one hour before bedtime. He emphasized he does not blame parents, acknowledging the pressures of modern life often lead to screens being used as a convenient way to occupy children. However, he believes stronger protections are needed.
Chatterjee’s advocacy extends to calling for an end to screen-based homework assignments. He believes that a focus on preventative approaches is crucial, linking many modern health problems – including anxiety, depression, obesity, and sleep disorders – to lifestyle factors. He stressed the importance of being fully present in the moment, arguing that constant digital distraction hinders genuine connection and happiness.
“We have to be able to be fully present, because that’s where connection and happiness arrive from,” Chatterjee stated. He explained that digital devices train the brain to seek constant distraction, undermining the ability to focus and appreciate real-life experiences.
