Doctors Warn of Child Health Crisis as Nearly One Million Pupils Use Screens in Almost Every Lesson
More than 150 clinicians say an over-reliance on untested educational technology is denying children vital development opportunities, with around one million pupils now spending nearly every lesson on screens.
More than 150 clinicians have warned that children are being denied vital development opportunities because schools rely too heavily on untested educational technology, with around one million pupils now spending nearly every lesson on screens.
The doctors describe the situation as a health crisis, arguing that the widespread use of screens in classrooms is taking place without adequate evidence about the long-term effects on children's development, eyesight and wellbeing.
The warning reflects growing concern among medical professionals that education technology, often marketed as a way to modernise teaching, has been adopted at scale before its impact on young people has been properly assessed. The clinicians say the result is a generation of pupils whose school day is dominated by digital devices at the expense of other forms of learning and interaction.
According to the group, about one million children in the UK now use screens in nearly all of their lessons. That figure suggests the practice is no longer confined to a few pioneering schools but has become a routine feature of mainstream education, affecting pupils across age groups and subjects.
The doctors argue that this shift has happened with little scrutiny of the products involved. They describe many of the educational technology tools and software packages used in schools as untested, meaning that claims about their benefits have not been matched by independent evidence about their effects on health or learning.
Their central concern is that screen-based lessons may displace activities that are essential to child development. These include face-to-face interaction, physical activity, handwriting, reading from paper and other practical forms of learning that support concentration, motor skills and social development. When screens occupy almost every lesson, the clinicians warn, opportunities to build those skills are reduced.
The warning also touches on eyesight. Prolonged close-up screen use has been linked in wider medical debate to eye strain and short-sightedness in children, and the clinicians' intervention places the classroom at the centre of that discussion. Because pupils spend so much of their day in school, any risks associated with sustained screen exposure are amplified by the scale and regularity of use in lessons.
The group's intervention is aimed at policymakers, school leaders and technology suppliers as much as at parents. By framing the issue as a crisis, the clinicians are pressing for greater caution, better evidence and clearer guidance before further expansion of screen-based teaching. They are not calling for technology to be abandoned, but for its use to be justified by research and balanced against other methods of instruction.
The concerns come amid a broader public debate about children's screen time, which has focused largely on smartphones, social media and entertainment. The doctors' warning extends that debate into the classroom, where digital devices are often presented as essential tools rather than optional aids. That distinction matters, because parents have little control over how much time their children spend on screens during the school day.
For schools, the challenge is to weigh the promised benefits of educational technology, such as personalised learning and access to online resources, against the risks highlighted by clinicians. For the government and regulators, the warning raises questions about how educational products are evaluated and whether schools receive enough independent advice before committing to expensive software and hardware.
The clinicians' message is that the burden of proof should not fall on children. Until the effects of near-constant screen use in lessons are properly understood, they argue, the current approach risks trading proven forms of learning for unproven digital substitutes. With around a million pupils affected, the group says the issue is now too large to be treated as a matter of individual school choice.
