In an era where apps compete for users' attention, digital time management has become a skill no less important than any other life skill. As short videos (Reels) have become part of the daily routine for millions of people worldwide, a new scientific study raises questions about the impact of this fast-paced content on the brain, particularly regarding focus and attention. The study, published in the journal Frontiers in Human Neuroscience, found that intensive viewing of short videos on a mobile phone is linked to decreased activity in the frontal lobe of the brain, the region responsible for executive functions, decision-making, and behavior control. The study involved 48 young people with an average age of 21. Participants underwent tests to measure attention functions, and brain activity was recorded using electroencephalography (EEG). While the results are significant, the researchers emphasized that the study shows a correlation, not a direct causal link. Balanced viewing, along with activities that enhance focus, such as reading or deep learning, may help maintain attention. In the case of habituation to fast, fragmented content, the brain's tolerance for long-term tasks may decline. The findings do not necessarily mean a complete abstinence from watching short videos, but they highlight the importance of moderation. The researchers also used a scale to assess the tendency to 'short video addiction,' then compared the results with indicators of neural activity in the frontal cortex. The data showed a negative correlation between intensive short video viewing and activity indicators in brain regions responsible for executive control. That is, they do not prove that short videos 'cause' a lack of focus, but suggest that those who watch them frequently tend to score lower on some attention functions. Additionally, the sample size was limited, and the age group was narrow, which calls for broader studies to confirm the results. Why might the brain be affected? Some researchers speculate that continuous exposure to fast-paced, short-duration content may condition the brain to a repetitive and rapid stimulation pattern, making tasks that require deep concentration or a long time seem more difficult. The frontal lobe, responsible for planning, decision-making, and attention control, is typically influenced by activities that require sustained cognitive effort. In other words, the higher the viewing rate, the lower some indicators of activity related to focus and self-control.
