Prevention Over Reaction: Adults Must Address Screen Exposure Risks Proactively

We have handed our children devices we did not understand, and now we are beginning to see the cost. The author of this piece opens with an apology—one offered on behalf of all adults to the teenagers who received smartphones and tablets without guardrails, without preparation, without anyone asking whether the technology might harm them. We did not know then. Now we do.

The evidence has arrived in pieces, each one a small crisis that forces our attention. First came cyberbullying and grooming. Then viral challenges, which materialized as bomb threats in schools across the country. Each time, adults react—we convene meetings, we implement protocols, we address the emergency in front of us. But we remain trapped in a cycle of response rather than prevention, treating symptoms as they surface instead of understanding the underlying condition.

The underlying condition is this: excessive screen exposure rewires the developing brain in ways that persist long after the device is set down. The dopamine surges that come from notifications, likes, and endless content create structural changes in neural tissue. Over time, the real world—unfiltered, unoptimized, without constant stimulation—becomes intolerable. Everything irritates. Everything hurts. Everything exhausts. In the most severe cases, teenagers lose the will to live. This is not metaphor. This is what the emerging research suggests is happening to a generation.

The dangers are numerous and overlapping. Nine in ten children consume pornography, often beginning by age eight or whenever they first access a device—and ninety percent of their parents do not know this is happening. The exposure shapes their understanding of sexuality, normalizing violence and the objectification of women. Gaming platforms engineer addiction through gambling mechanics, with losses that can spiral into financial and psychological devastation. Social media platforms are built on comparison, and comparison breeds anxiety, depression, and eating disorders. Artificial intelligence is being consulted as a counselor or therapist by young people who do not understand its limitations or its incentives.

Other countries are grappling with these realities openly. Argentina has not yet caught up to the conversation. The author points out that we tend to focus on whichever crisis is loudest in the moment, missing the larger architecture of harm. We need to shift. Prevention means understanding these dangers ourselves first—really understanding them, not in headlines but in depth. It means talking to our children about them before the harms manifest. Research from UNICEF confirms that adolescents who know about these risks and discuss them with their parents regulate their own behavior far better than those who do not.

The author shares preliminary results from a survey of over 150 teenagers who had read her book on the subject. Ninety-seven percent said the information helped them. Fifty-seven percent reported making actual changes to their device use—forty percent on their own, seventeen percent with adult support. The remaining forty percent found the information valuable but struggled to implement change. They needed help. They wanted help. They were afraid to ask for it. This reveals something crucial: awareness alone is not enough. Children need adults present, attentive, and willing to set boundaries alongside them.

The practical steps are concrete. Delay device access as long as possible—specialists recommend age fourteen at the earliest, with social media withheld until sixteen. In Argentina, the average age of first smartphone is 9.6 years. Establish family agreements about when and where devices are used: never in bedrooms, never at meals, never in bathrooms. Adults must model restraint. The conversations must happen early and often, before pornography teaches sexuality, before gambling platforms teach risk, before social comparison teaches shame. These conversations require empathy, not judgment. They require presence. And they require remembering, always, that none of this is the child's fault.

The author is not trying to frighten anyone into paralysis. She is trying to mobilize adults toward a different posture—one of informed engagement rather than reactive panic. She believes that working together, with clear eyes and sustained attention, we can change the trajectory. The alternative is to continue as we have been: waiting for the next crisis, responding when it arrives, and calling that protection.
