A study by the University of Duisburg-Essen, published in PLOS One, surveyed 900 German adults in 2025 who engaged in gaming, pornography, social networking or online shopping. Those spending excessive time online reported higher stress, worse mood and greater neglect of other activities. The findings point to a clear link between heavy internet use and reduced psychological well-being.
