Semmelweis University study links smartphone habits to cognitive risks

Researchers at Semmelweis University have identified that the manner in which smartphones are used may be more impactful on health than total screen time. A study published in Acta Psychologica suggests that problematic usage is closely linked to low self-control and the “fear of missing out” (FOMO), rather than personality traits like neuroticism alone.

By studying students aged 18 to 35, researchers categorized users into three groups: “purely social,” “light use,” and “compulsive use.” The compulsive group, which accounts for approximately one-third of participants, spends four to five hours daily primarily consuming online content rather than communicating with others. This pattern is associated with diminished memory, reduced concentration, and disrupted sleep patterns.

Beyond cognitive effects, the study notes that prolonged use can lead to physical issues, such as poor posture, which may negatively affect balance and reaction times.
