Bedtime media use, psychological distress, and fatigue: a study of college students in Shaanxi Province, China

Based on the findings, psychological distress is indirectly associated with fatigue through the visual or auditory stimuli of bedtime media use. The visual and auditory stimuli exhibit different mediating effects among students with normal versus severe psychological distress. Interventions should focus on limiting bedtime media use to enhance health and reduce fatigue among college students experiencing psychological distress. Future studies may use longitudinal designs to establish causality or explore the reverse relationship between psychological distress and fatigue for a more robust finding.
