Experts Warn About Screen Time’s Impact on Children’s Health
Andrea Chrysanthou faces a common struggle these days: controlling her 13-year-old son Nathaniel’s screen time. Based in Toronto, Chrysanthou heads the advocacy group Children First Canada. She shares, “My son knows he’s addicted,” adding that he has asked for help to cut down on his digital device usage. However, as soon as she steps away, he reaches for the device again.
Nathaniel’s experience reflects a widespread issue among children globally, as highlighted by new research published in the medical journal The Lancet. The studies reveal that excessive screen time puts kids’ physical and mental health at risk. Jay Shaw, a co-author of the research and assistant professor at the University of Toronto, emphasizes, “We need to take action to protect children’s health.”
The researchers stressed that while their work sheds light on the potential dangers of screen addiction, getting a full grasp of the issue is difficult without access to data from tech companies, which currently aren’t obligated to share it. They argue that screen addiction is a public health concern, necessitating governmental intervention.
Chrysanthou believes parents shouldn’t bear the full responsibility for managing screen time. “We want the companies and platforms to take responsibility and ensure their platforms are safe,” she said.
Findings from the Research
The researchers examined nearly 2,800 studies, involving over nine million participants. They found that excessive screen time is linked to poor sleep and delays in cognitive, emotional, and social development among children aged 10 and under. For those aged 10 to 24, the consequences are even broader, including mental health issues, lower physical activity, substance abuse, and thoughts of self-harm.
“I think the dangers of digital media, especially for young people, are becoming evident,” remarked Shaw. Dr. Rachel Mitchell, a psychiatrist at Sunnybrook Health Sciences Centre in Toronto, echoed this sentiment. She noted that many digital platforms weren’t designed with children in mind, making them particularly vulnerable due to their still-developing brains.
Mitchell pointed out that attention-seeking features like autoplay and push notifications can make it hard for people of all ages to limit their screen time. “If adults struggle with this, it’s tough to expect children to manage,” she said.
Comparing Tech to Tobacco
Shaw likened the situation to prior public health issues, such as smoking. He believes society may be at a critical moment with technology. If not addressed, digital devices could become more harmful than beneficial.
However, Mitchell argued that unlike smoking—which has no benefits—digital media can be advantageous when used wisely. She highlighted that moderate use of technology can aid in education and learning. “To harness these benefits, we must manage the risks associated with screen time,” she added.
The research shows the widespread nature of these problems, making it imperative for government intervention and involvement from technology companies. Some companies, like Meta, TikTok, and Snap Inc., have started to introduce measures to help manage screen time. For instance, Meta’s platforms agreed to enforce age limits following a significant lawsuit settlement. TikTok has a default setting that limits use to one hour for users aged 13 to 17, while Snap Inc.’s CEO expressed openness to implementing time restrictions for teenagers.
Seeking More Transparency
Shaw and his fellow researchers aim for their findings to guide public health policy on managing digital media use among youth. However, they stress that without access to the relevant user data from tech companies, understanding the full extent of young people’s screen time and its effects will remain challenging.
Digital safety legislation, like the proposed Safe Social Media Act in Canada, could help provide transparency and compel companies to ensure the safety of younger users. The bill would enforce restrictions on accounts for users under 16 unless adequate safety measures are in place.
Despite the push for regulation, experts including Chrysanthou believe simply banning children from social media might not work, as many may find ways around restrictions. “We want companies to take responsibility and create safer platforms,” she stated.
As screen time continues to be a major topic of concern for parents, experts, and policymakers, the focus now shifts toward finding solutions that prioritize children’s safety and well-being in a digitally-driven world.
