A recent analysis conducted by researchers at the University of Duisburg-Essen has identified a correlation between high levels of internet usage and negative psychological outcomes. The study, published in the journal PLOS One, surveyed 900 adults in Germany during 2025 who had participated in various online activities, including gaming, social networking, pornography consumption, and online shopping, within the previous year.

The research team categorized the participants' internet habits into three distinct groups: pathological, risky, and non-problematic. The findings indicate that individuals whose habits fall into the 'problematic' categories—which encompass both pathological and risky usage—are more likely to report elevated stress levels and a decline in overall mood. Furthermore, the study notes that these individuals are more prone to neglecting other essential daily activities in favor of their online pursuits.

While the study highlights these associations, it focuses specifically on the frequency and nature of the usage rather than establishing a direct causal link. The researchers utilized this data to distinguish between healthy digital habits and those that may interfere with a person's quality of life. The study serves as a contribution to the ongoing academic discussion regarding how digital consumption patterns affect mental health in an increasingly connected society.
