Frequent viewing of short videos deteriorates cognitive functions.
Frequent viewing of short videos in formats like TikTok, Reels, and Shorts has been linked to a decline in cognitive functions and mental health. This conclusion was reached by the authors of a large systematic review and meta-analysis published in the Psychological Bulletin (PB), which combined data from 71 studies involving nearly 100,000 people.
The analysis revealed a moderate negative correlation between engagement with short videos and attention performance. The most pronounced effects were observed in decreased concentration and weakened inhibitory control — the ability to maintain focus and suppress impulsive reactions. In other words, active viewers of short clips often experience difficulties with concentration and self-control.
Negative associations were also found with indicators of mental well-being. Higher engagement with short videos was accompanied by increased levels of anxiety and stress, as well as a decline in sleep quality and overall well-being. These effects were observed in both youth and adult users.
At the same time, the decisive factor, according to the authors, was not so much the act of viewing itself, but rather the compulsive nature of usage. The most significant harm was recorded in studies that assessed addiction to short videos, rather than just the time spent in the apps.
The authors emphasize that the identified connections do not prove causality, but indicate potential risks to cognitive and mental health with regular and uncontrolled consumption of short video content.
