Beyond screen time: what we don't understand about young people and technology

BarcelonaIn Europe, the debate about children, adolescents, and technology is intensifying. There is increasing pressure to limit access to social networks and strengthen age verification mechanisms. This shift responds to a legitimate concern. But even so, the question remains too simple: how many hours do they spend in front of a screen? Reducing the problem to a sum of hours is convenient, but it distances us from what truly matters.

Research in recent years has made it clear that talking only about "screen time" is insufficient. It's not the same to spend an hour doing homework, watching videos non-stop at dawn, playing online in dynamics of constant pressure, competition, and reward, seeking comfort in a moment of anxiety, or asking an artificial intelligence tool to do part of the cognitive work for us. Nor is it the same to do so at ten, fourteen, or twenty-two years old. Digital technology is not a homogeneous exposure, and neither are its effects. In some cases, it can be a useful tool; in others, a means of escape, a source of emotional dependence, or a practice that deregulates sleep and daily life.

This does not mean that time is irrelevant. It means, rather, that it is too broad an indicator to explain a much finer phenomenon. What we should be looking at is not just how much use there is, but what use, when, for what purpose, and under what personal and social conditions it occurs.

And this forces us to also look at what often remains outside the debate: the concrete lives of families. Because the mobile phone, many times, is a free nanny, it is a digital pacifier, it is an emergency solution in tired parenting, on an impossible afternoon, or in a home where the adult has to sustain too many things at once. This use should not be trivialized. But it should not be moralized with superiority either. When a screen becomes a calming agent, it often reveals tiredness, lack of support, overload, and, in some cases, inequality.

Pre-existing problem amplifier

Therefore, it is increasingly reasonable to speak of digital vulnerability rather than just "screen excess." There are children and adolescents who may be more sensitive to certain digital environments because they already present more irritability, more self-regulation difficulties, more sleep disturbances, or a greater need for external validation. In these cases, technology can act as an amplifier of a pre-existing problem, not necessarily as its sole cause. This distinction is important because it helps us avoid both simplistic alarmism and the temptation to minimize the problem.

It also forces us to rethink prevention. If the problem were only quantitative, the answer would be simple: more time limits and that's it. But if the problem is qualitative and contextual, prevention must be smarter. This means working in school on the relationship with frustration and with persuasive digital environments; helping families distinguish between protective uses and deregulatory uses; paying more attention to nighttime use and sleep displacement; and demanding more responsibility from platforms regarding the attention and reinforcement logics they impose.

Education and prevention

It is at this point that the European turn towards tougher restrictions deserves to be taken seriously, but also thought about more deeply. At certain stages of development, reducing or delaying access to certain digital environments can be a reasonable protective measure. The challenge is to understand that this protection, even if it may be necessary, does not exhaust all the educational and preventive work that will subsequently need to be done.

This is even more urgent now that the debate is no longer just about social networks or video games. The arrival of generative artificial intelligence introduces a new question: when does a digital tool help us think, and when, on the other hand, does it begin to replace too many processes that we should sustain ourselves? In young adults experiencing moments of uncertainty, loneliness, or transition, AI can function as a useful support, but it can also foster forms of cognitive or relational dependence if used without limits or criteria.

Continuing to talk only about screen time is no longer enough. If we truly want to protect the mental health of new generations, we will have to start asking ourselves what conditions favor healthier development in the midst of a digitized world.
