A new Finnish study suggests that screen time from childhood may not be entirely harmful for young people. Researchers found that more screen time during childhood was actually linked to better cognitive processing in teenagers. This surprising finding challenges many common beliefs about digital device use among youth.[news-medical]
Screen Time Can Support Active Thinking
The study, which followed children for eight years, indicates that screen time can support thinking and learning. Doctoral Researcher Petri Jalanko from the University of Jyväskylä emphasized that people should not view screen time as only harmful. He stated that the crucial factor is what children do with their screens. Parents and teachers should encourage children to use devices in ways that promote active thinking, problem-solving, creativity, and learning.[news-medical]
The research is part of the ongoing PANIC study, which examines children's physical activity and nutrition. It involved 124 girls and 136 boys. The study looked at how physical activity, sedentary behavior, and screen time from childhood through adolescence relate to cognitive processing. It also explored potential differences between sexes in these connections.[news-medical+2]
A Nuanced View of Digital Engagement
This new evidence adds an important layer to the complex discussion around screen time and brain development. For years, much of the focus has been on the potential negative impacts of digital media. However, some experts have long argued for a more balanced perspective. Dr. Michael Rich, director of the Center on Media and Child Health at Boston Children's Hospital, noted that "it's not how long we're using screens that really matters; it's how we're using them and what's happening in our brains in response." He believes that digital devices can both enhance learning and help build communities.[hms]
Other research has also pointed to specific benefits. A study published in August 2026 found that 15-year-olds who spent more than an hour a day on social media apps were less likely to report 'above-average difficulties' compared to those who used these apps for less time. This suggests that social media and messaging could potentially strengthen friendships and offer young people more support. However, researchers cautioned that adolescents who already have better social skills might simply be more inclined to use these platforms.[hms+2]
Certain types of screen activities, such as video games, can also help children and young people develop important skills. These include problem-solving, spatial reasoning, strategic thinking, fine motor skills, and hand-eye coordination. Screens also provide access to a wealth of educational apps, websites, and games, offering valuable learning experiences and information. They can foster creativity, global awareness, and even prepare young people for future job opportunities.[sciencealert+2]
Balancing Benefits with Potential Risks
While the Finnish study highlights unexpected benefits, it is important to consider the broader context of screen time research. Many studies have raised concerns about excessive or unregulated screen use, particularly for younger children. An observational study from the National Institutes of Health (NIH) in 2018 suggested that limiting screen time for children aged 8 to 11 to two hours a day could improve brain function, memory, attention, and information processing speed. This effect was even stronger when combined with at least nine hours of sleep each night.[magnushealth]
More recently, a 2022 study from Cincinnati Children's indicated that high amounts of screen time could impact brain growth and development in children as young as three to five years old. These effects were observed in brain areas responsible for visual processing, empathy, attention, complex memory, and early reading skills. Another study from December 2025 linked high screen exposure before age two to faster brain maturation, slower decision-making, and increased anxiety by adolescence.[magnushealth+2]
Concerns also exist about how digital media can interfere with sleep patterns. Devices that emit blue light, like smartphones, can disrupt sleep by suppressing melatonin, a hormone vital for sleep. Many teenagers who stay up late texting may not only get less sleep but also miss out on crucial REM sleep, which is essential for processing and storing daily information into memory.[neurosciencenews+1]
However, not all research points to negative impacts. A 2023 study from the University of Oxford, which analyzed data from nearly 12,000 children in the United States, found no evidence that screen time affected their brain function or overall well-being. This research, using data from the large-scale Adolescent Brain Cognitive Development (ABCD) Study, covered a two-year period and included various digital activities such as watching TV, YouTube, playing video games, and social media use. Even children with high rates of digital engagement showed no signs of impaired brain development.[hms+2]
What This Means for Families and Future Research
The evolving understanding of screen time suggests that a blanket ban or strict limitation might not be the most effective approach. Instead, the focus should shift to the quality and context of screen engagement. As Doctoral Researcher Petri Jalanko advised, encouraging screen time that promotes active thinking, problem-solving, and learning is key.
Parents and educators can guide young people toward educational apps, creative projects, and interactive games that stimulate cognitive skills. It is also important to ensure that screen time is balanced with other essential activities, including physical movement, face-to-face social interaction, unstructured play, and sufficient sleep. Abalanced approach also includes setting healthy habits and focusing on emotional well-being.[news-medical+1]
Researchers continue to call for more in-depth studies, particularly longitudinal designs, to understand the causal links and specific effects of different types of screen content. Understanding how different screen activities influence brain development and well-being will allow for more tailored and effective guidelines for children and adolescents in the digital age.[brainbalancecenters+3]
