Scientists from Tianjin Pedagogical University have identified the harmful effects of excessive time spent watching short videos on TikTok and Instagram on brain function. This study was published in the latest issue of the "NeuroImage" journal. The researchers explored the impact of bright, fast-paced, and dynamic content in short videos on the brain, and the results were shocking.
According to the researchers, the findings revealed that people who actively watch short videos have their brain's "reward" system activated, similar to the effects of alcohol consumption or gambling. Excessive activation of these neural circuits leads to impulsiveness, decreased focus, and disruption in emotional regulation. Scientists compare this state to the effects of alcohol, as both can "over-saturate" the brain with dopamine.
The impact of short videos on everyday life is also evident in how activities like reading books, having dinner, or talking to people become less appealing. The brain loses interest in simple pleasures, and stronger stimuli are required for satisfaction. This resembles the mechanism of addiction, where stronger stimuli are needed to achieve satisfaction.
In particular, the prefrontal cortex, responsible for decision-making and attention, is affected. Bright, fast stimuli interfere with the ability to focus on one task, retain information, and control impulses.
The rise of these changes in our country is concerning. Researchers recommend consciously using screens, reducing screen time, taking breaks every 10-15 minutes, and practicing digital hygiene.
Thus, an important focus should be on "digital health", which will help maintain clarity of thinking and mental well-being, without giving up digital entertainment.
