PEER-REVIEWED & PARENT-TESTED

The Research Behind Speel

We are not here to shame anyone for handing over a phone in a hard moment. We know exactly how real those moments are.

A long wait for food. A restless toddler in the car. A flight delay. A child who is done, and a parent who just needs something that works.

Speel exists because screens are often the easiest option in the moment, but not always the option parents feel best about. This page pulls together the research that helped shape our thinking.

The goal is not perfection. It is having a better option when you need one.

What the research keeps pointing to

Across recent reviews and large-scale studies, the same themes come up again and again:
  • too much screen time is linked to poorer sleep
  • attention and impulsivity can worsen over time
  • physical activity often gets replaced
  • parent-child interaction can decrease
  • emotional regulation can get harder
  • not all screen use is equal, and context matters

That nuance matters to us. This is not about fear or guilt. It is about balance, boundaries, and giving families practical screen-free options for real life.

Screen Time, Impulsivity, and ADHD Symptoms in Adolescents

Researchers followed nearly 4,000 Canadian teenagers over five years, tracking daily screen use alongside attention, memory, and impulsivity. They found that higher screen time, especially social media use, was linked to more ADHD-related symptoms over time.

The most important finding was not just attention itself, but impulsivity. The study suggests that screens may increase impulsive behaviour, and that impulsivity then helps drive later struggles with attention and hyperactivity. Social media showed the most lasting effect, with its influence carrying into the following year.

For parents, this adds to a growing body of research suggesting that the type of screen use matters, and that repeated, highly stimulating digital experiences may affect how children regulate attention over time.

Screen Media Overuse: Physical, Cognitive, and Behavioural Outcomes in Children and Adolescents

This review brought together findings from many studies looking at how screen overuse affects children's health and development. The patterns were consistent: too much screen time was associated with shorter and poorer-quality sleep, a higher likelihood of overweight and obesity, weaker executive functioning, lower academic performance, and increased anxiety and depression.

One of the most helpful insights from this review is that the relationship often works both ways. Children who are already struggling with sleep, behaviour, or emotional wellbeing may turn to screens more, and more screen use may then deepen those same difficulties.

In other words, screen time is rarely just about entertainment. It often sits inside a bigger picture of routine, regulation, energy, and family life.

Effects of Excessive Screen Time on Child Development: An Updated Review

This review looked at four major areas of child development: cognitive development, language development, social and emotional development, and physical health.

The authors found that while screens can support learning in limited and age-appropriate ways, overuse was linked to disrupted language development, less parent-child interaction, emotional difficulties, aggression, obesity, sleep problems, anxiety, and depression.

What stands out most is that the strongest protective factors were not complicated. Parents being aware, setting clear boundaries, and modelling healthy habits made the biggest difference.

That matters because most parents are not looking for a perfect system. They are looking for practical ways to make everyday life feel calmer and more intentional.

Kar et al. (2025) — Children (MDPI)

Impact of Screen Time on Development of Children

This structured review examined 34 studies across ten years of research, covering children from birth to 18 years old across physical, cognitive, emotional, social, and language development.

The findings showed that excessive or passive screen use was linked to attention difficulties, delayed language, reduced physical activity, poor sleep, and challenges with emotional regulation and social skills.

Importantly, this review also makes space for nuance. Not all screen time is harmful. Educational content used with parental involvement may support learning and development. The authors emphasise that duration, content, and context all matter.

That is a big part of how we think about this at Speel too. This is not an all-or-nothing conversation. It is about what children are watching, how long they are on screens, and what those screens are replacing.

Excessive Screen Time, Mental Health, and ADHD: Physical Activity and Sleep as Mediators

Using data from more than 50,000 children and adolescents in the United States during the COVID-19 pandemic, this study looked at how screen time connects to anxiety, depression, behavioural problems, and ADHD.

Children with four or more hours of daily screen time showed significantly higher risks across all four outcomes. The key finding was that physical activity and sleep explained much of that connection. In simple terms, screen time often displaced movement and disrupted bedtime routines, and those changes then affected mental health and behaviour.

Physical activity showed the strongest protective effect, followed by regular sleep habits.

That matters because reducing screen time is usually most effective when it is not just about taking something away. It works better when it is paired with something better to do instead.

What these studies seem to agree on

Different researchers, different age groups, and different methods still point back to a few shared ideas:
Screens are not always the problem on their own. The bigger issue is often what they crowd out.

-Sleep.

-Movement.

-Conversation.

-Quiet play.

-Boredom that turns into imagination.

-Shared moments between parent and child.

The research also makes something else clear: not all screen time is equal, and not every family situation is the same. Educational content with a parent nearby is not the same as passive, high-volume screen use that becomes the default in every hard moment.

That is why we try to keep this conversation grounded in empathy, not judgement.

Where Speel Fits In

Speel is not about pretending screens do not have a place.

It is about helping parents have another option ready before the tension rises.

Something screen-free. Something mess-free. Something easy to carry. Something that can hold their attention long enough to get through the wait, the meal, the car ride, or the in-between moment without turning every outing into a battle.

Because often, that is what parents are really looking for:

  • A better option when they need one
  • Something that actually works
  • A way to keep little hands busy without defaulting to a screen
  • A chance to eat their meal while it is still warm
