Not long ago, while doing house chores, I handed my youngest child his father’s iPad to keep him occupied. But an uneasy feeling crept in—I hadn’t been monitoring how long he’d been using it or what he was watching. I decided it was time to take it away.
Cue a meltdown. He kicked, screamed, clung to the device, and even tried to push me away with all the might of an angry preschooler. It wasn’t a proud parenting moment, and his intense reaction left me unsettled.
My older children are already immersed in the world of social media, virtual reality, and online games, which brings its own set of worries. They often joke with each other about the need to “touch grass”—a reminder to step away from screens and reconnect with the real world.
It’s well-known that Apple co-founder Steve Jobs didn’t allow his young children to use iPads. Microsoft’s Bill Gates imposed similar restrictions in his household.
Is Screen Time Really That Harmful?
For years, screen time has been blamed for a range of issues: rising rates of depression, behavioral challenges, and poor sleep among young people. Baroness Susan Greenfield, a neuroscientist, once likened the digital world’s impact on developing brains to the early days of climate change—alarming, yet largely ignored.
Though many are now paying attention, others suggest the panic might be exaggerated.
An editorial in the British Medical Journal dismissed Baroness Greenfield’s assertions as misleading and unsupported by robust evidence. More recently, a group of UK scientists echoed that sentiment, claiming that there’s little solid proof linking screen use to significant mental health harm.
The Debate Among Experts
Psychologist Pete Etchells from Bath Spa University has examined hundreds of studies on screen time and young people’s mental health. In his book Unlocked: The Real Science of Screen Time, he argues that many of the alarming conclusions about screens are based on flawed or inconsistent research.
“The hard evidence for the supposed damage from screen use just doesn’t exist,” Etchells writes.
A 2021 study by the American Psychological Association supports this view. It analyzed 33 studies from 2015 to 2019 and concluded that screen use, including social media and gaming, had only a minimal impact on mental well-being.
Concerns about blue light disrupting sleep have also been questioned. A global review of 11 studies in 2024 found no consistent evidence that screen exposure before bedtime significantly interferes with sleep.
The Flaws in Screen Time Research
A major issue, according to Etchells, is that most research relies on self-reported data. That means children and teens are asked to estimate how much time they spend on screens and how it affects them—data that’s inherently unreliable.
Etchells warns against mistaking correlation for causation. For example, ice cream sales and skin cancer both spike in summer, but one doesn’t cause the other—they simply share a seasonal link.
He shared a study inspired by a family doctor who had noticed more young patients discussing anxiety while also using their phones frequently in the waiting room. Data analysis showed a correlation, but also revealed that time spent alone was a much stronger factor in their mental health struggles than screen use itself.
Not All Screen Time is Equal
Etchells argues that “screen time” is an overly broad term. Watching educational videos or video chatting with friends is very different from aimlessly scrolling through negative content. The context, content, and purpose of screen use matter greatly.
A study of 11,500 brain scans from children aged 9 to 12 found some changes in brain connectivity associated with screen use. However, there was no evidence linking this to poor cognitive development or mental health issues. Oxford professor Andrew Przybylski, who co-led the study, has long studied the effects of digital media and found that screen use can even have positive effects.
“If screens truly rewired the brain in a damaging way, we’d see it clearly in such large-scale data. But we don’t,” Etchells notes.
This perspective is shared by Cardiff University’s Professor Chris Chambers, who argues that if human brains were so easily harmed by environmental changes like screen exposure, our species wouldn’t have survived evolution.
The Real Risks, and the Social Divide
That said, both Etchells and Przybylski acknowledge real online dangers—such as harmful content, cyberbullying, and grooming. But they caution against overly restrictive rules, which could drive screen use underground and make it more tempting as a “forbidden fruit.”
Campaigns like Smartphone Free Childhood are gaining traction, with over 150,000 pledging to delay smartphone use until at least age 14. Meanwhile, Jean Twenge, a psychology professor at San Diego State University, sees a clear link between smartphones and mental health decline in teens. She supports delaying screen access, arguing that teenagers are better equipped emotionally and socially to handle digital life by age 16.
One Danish study in 2024 limited kids’ screen time to three hours a week for two weeks. Results showed improved mood and social behavior. Another UK study found that teenage girls who used social media more often reported higher rates of depression.
Twenge sums it up: “More time alone with screens, less sleep, fewer in-person interactions—it’s a toxic mix for mental health. Why is that controversial?”
Parental Anxiety and Inconsistent Guidelines
Etchells, a parent himself, understands the confusion and pressure families face. The science is still developing, and advice varies widely. The World Health Organization recommends no screen time for infants and a one-hour daily cap for under-fours, mainly to encourage physical activity. But neither the American Academy of Pediatrics nor the UK’s Royal College of Paediatrics offers firm time limits.
Dr. Jenny Radesky of the University of Michigan argues that public discussion around parenting and tech is becoming increasingly judgmental. Instead of clarifying the science, it often just fuels parental guilt.
Reflecting on her own child’s iPad tantrum, the writer admits it felt serious in the moment—but similar outbursts have happened over non-digital activities too. It’s a common theme among parents, some of whom are strict about screen use, while others are more lenient.
A Future Still Unclear
The truth is, we don’t yet have definitive answers. Scientific understanding lags behind the rapid pace of technology. In the meantime, parents are left to navigate this space with a mix of instinct, trial and error, and evolving research.
As screens become wearables, social platforms become more intimate, and AI becomes a tool for everything from homework to therapy, the tech world continues to transform—whether or not we allow our children to be part of it.
