Children are spending more time in digital worlds than the real one, the Senedd has heard, with excessive screen use shaping behaviour and health in ways society cannot ignore.

Labour’s John Griffiths expressed concerns about the impact of smartphones and online gaming on young people amid an “epidemic of screen use” in Wales.

Mr Griffiths titled the debate “Locked in, Bruh!” – “the state of playing a video game while oblivious to anything else” – on the suggestion of Tom, a teenager from Newport.

He raised research from the Centre for Social Justice, a thinktank, which estimates that up to 814,000 UK children aged three to five are already engaging with social media.

The Newport East Senedd Member told the chamber two-thirds of primary school pupils in Wales have their own smartphone by the age of 11.

‘Reel scrolling’

Mr Griffiths said boys spend two hours more a day on online gaming while girls spend more time on social media and “reel scrolling” which has been linked to damaging self-esteem.

He told Senedd Members: “Boys are becoming more short-tempered and violent when exposed to violent video games and there is, rightly, much concern that children in more deprived families are particularly vulnerable.”

Mr Griffiths, who was first elected in 1999 and will stand down in 2026, said children aged five to 16 spend at least six hours a day looking at a screen. He added that for children, aged 11 to 14, that figure rises to nine hours a day.

He pointed to research showing more than 70% of young people in the UK do not undertake an hour of physical activity a day yet have at least six hours to spend looking at a screen.

He said: “Children are sat inside with a screen at the end of their nose and are not spending time outside enjoying their local communities or playing and interacting with friends.”

‘Tantrums and tears’

Mr Griffiths warned of increasing levels of obesity and rising numbers of young people reporting vision problems, with one in three children globally now short-sighted.

He told the Senedd: “As for the mental health and wider social impacts, anxiety and depression are increasingly linked to excessive screen use as is sleep disruption – with social media interfering with rest and emotional development.”

He raised a New Zealand study of more than 6,000 children that found a correlation between excessive screen time and below-average performance in literacy and numeracy. He warned children have increasingly shortened attention spans and an inability to concentrate.

Mr Griffiths shared the case of his constituent, Danielle, who said her son becomes more aggressive and snappier after a significant time gaming. Lucy, another constituent, explained how her children find the endless reels on social media addictive.

“Once they start scrolling, it’s hard to break that cycle,” the Senedd Member said. “And when she and her husband take the devices away, it often results in tantrums and tears.”

‘Sickening’

Mr Griffiths raised the example of countries such as Australia, France and Italy which have introduced strict age checks and bans on social media for under 16s.

He acknowledged such a policy would need to come from the UK Government because powers over internet services are not devolved. But he said Wales has the authority to introduce measures through education policy on, for example, smartphones in schools.

The Tories’ Sam Rowlands warned algorithms are having a “sickening” effect on teenagers who are eight times more likely to act on self-harm urges when exposed to such content. “TikTok users with eating disorders receive over 4,000% more toxic content,” he warned.

Responding to Wednesday’s (December 17) debate, Jane Hutt recognised how so-called doom scrolling can have a detrimental impact on young people.

Wales’ social justice secretary said: “We are living through profound change. Childhood today is shaped by technology in ways that were unimaginable a generation ago… For many young people, screens, smartphones and online gaming are part of everyday life.”
