Wait, cease scrolling! How lengthy have you ever been in your cellphone at the moment? Is social media rotting your mind? We’re continually asking questions like these, however simply how apprehensive must you be about your display screen time?
There are actually a whole lot of hundreds of research display screen time, and lots of of them have discovered hyperlinks between utilizing screens and an enormous number of well being points, together with despair, anxiousness, poor sleep, weight problems, diabetes and even suicide. All of it sounds fairly unhealthy.
There’s only one query: are screens themselves inflicting these points, or is poor well being inflicting elevated display screen time? Or may there even be an unknown, third issue influencing each?
The overwhelming majority of those research can’t let you know, as a result of they merely present a correlation between display screen time and well being. Figuring out causation – the true impression display screen time is having – is far more durable.
To resolve this, researchers conduct meta-analyses that pull collectively a whole lot of high-quality research utilizing extra superior statistical methods. Doing this, a number of the hurt appears to vanish.
My favorite such meta-analysis – sure, in fact I’ve a favorite meta-analysis – was carried out in 2019. The researchers, Amy Orben and Andrew Przybylski, each then on the College of Oxford, checked out an enormous dataset of questionnaires given to youngsters, permitting them to check the results of greater than 20,000 various factors on the individuals’ psychological well being.
Crunching the numbers, they discovered that solely 0.4 per cent of adolescent well-being was associated to display screen use, a stage of damaging impact corresponding to consuming potatoes. By comparability, being bullied was related to greater than 4 instances this damaging impact, whereas getting sufficient sleep and consuming a great breakfast have been related to a lot bigger constructive results.

What the info appears to be telling us is that on common – on a inhabitants stage – the constructive and damaging results of screens are small

So, display screen time is ok? Nicely, once more, let’s not be so hasty. Regardless of placing the hyperlinks between display screen time and psychological well being in context with different components, these are nonetheless solely correlations. Folks’s lives are messy, and extracting causation from messy knowledge is tough.
One method to unpick the noise is perhaps to ask what we really imply by display screen time. Watching TV, scrolling via social media in your cellphone, enjoying video video games, studying an e-book or listening to a science journalist speak about display screen time all contain observing a display screen, however would we anticipate all of them to have the identical impression on our well being?
Many research don’t take a very subtle method to this query, merely counting up the variety of hours spent a display screen – and to make issues worse, this knowledge is usually self-reported, which we all know makes it much less prone to be correct. (Come on, all of us lie about it.)
Even when we deal with simply social media, that encompasses so many issues. Arguing about politics on X till 3am and messaging your pals on WhatsApp are each examples of utilizing social media, however have they got the identical impact? A meta-analysis revealed in 2024 within the journal SSM – Psychological Well being tried to tease this out, discovering small constructive correlations between well-being and utilizing social media for communication or having a number of social media-based buddies. It additionally discovered small damaging correlations with evaluating your self with others on social media or with problematic social media use – what we’d name “being addicted” to social media. None of that sounds notably shocking, proper?
The place, then, does that depart us? Given the potential danger for hurt, we may undertake the precautionary precept, notably on the subject of youngsters. We may closely prohibit their display screen time and even introduce bans on sure sorts of tech use, like social media, because the UK and Australian governments are doing.
However I fear that doing this might see us miss out on the advantages of display screen time – info, social connection, leisure and extra. What the info appears to be telling us, as a lot as we are able to glean via all of the noise, is that on common – on a inhabitants stage – the constructive and damaging results of screens are small. That doesn’t imply there aren’t some individuals who expertise a lot bigger harms – these problematic customers I talked about earlier than – and we have to perceive far more to assist them.
Contemplating all that, how apprehensive must you be about display screen time? The reply is a posh one, based mostly on still-evolving analysis. In case you discover screens interfering along with your life in a significant approach, altering behaviour is perhaps helpful, as may looking for medical recommendation. For many of us, although, display screen use shouldn’t be notably excessive in your record of worries – and positively not as excessive as headlines may depart you to imagine.
