In this episode, Zhang Yiqin from the School of Information Management, Nanjing University, pointed out that digital overuse is not the same as internet addiction. Instead, it is a state of imbalance across the social, psychological, and physiological dimensions. Interestingly, it's not always the heaviest users who struggle the most. One's experience of fatigue, guilt or disrupted daily functioning after mobile use is more important than the hours of screen time itself. Yiqin is part of the team that won the Merit Award in the Research Paper category of the 2025 Tencent-CGS Academic Conference "Technology for Good: Driving Social Impact". Her teammates are Gong Hongcun (Shanxi University), Zheng Yuntian (National University of Singapore) and Deng Sanhong (Nanjing University).Follow us for more.
