Frequent viewing of short videos in formats like TikTok, Reels, and Shorts is associated with deterioration of cognitive functions and mental state. This conclusion was reached by the authors of a large systematic review and meta-analysis published in the journal Psychological Bulletin, which combined data from 71 studies involving nearly 100,000 people.

According to BAKU.WS with reference to Psychological Bulletin, the analysis revealed a moderate negative relationship between engagement with short videos and attention function. The most pronounced effects concerned decreased concentration and weakened inhibitory control - the ability to maintain focus and suppress impulsive reactions. Active viewers of short videos more often experience difficulties with concentration and self-control.

In addition, higher engagement with short video content was associated with deterioration of mental well-being: increased anxiety and stress, decreased sleep quality and general well-being. These effects were observed in both young people and adult users.

At the same time, the decisive factor was not the fact of viewing itself, but its compulsive nature. The most pronounced negative effect was recorded in studies that assessed dependence on short videos, rather than just time spent in applications.

The authors emphasize that the identified connections do not prove a cause-and-effect relationship, but indicate potential risks to cognitive and mental health with regular and uncontrolled consumption of short video content.
