Abstract :Introduction: Prolonged internet and social media use among university students is increasingly associated with adverse health outcomes, particularly in relation to musculoskeletal health and sleep quality. Extended screen exposure often leads to sustained non-ergonomic postures and physical inactivity, contributing to discomfort and pain in the neck, back, and upper extremities. Additionally, nighttime screen usage disrupts circadian rhythms by suppressing melatonin secretion, thereby delaying sleep onset and reducing overall sleep quality. This study aims to investigate the impact of internet and social media usage on musculoskeletal disorders and sleep quality in university students. Methods: A cross-sectional study was conducted involving 386 undergraduate students from nine academic programs at Dicle University. Data were collected through validated self-report instruments: the Young’s Internet Addiction Test (IAT) for assessing internet addiction, the Pittsburgh Sleep Quality Index (PSQI) for evaluating sleep quality, and the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) for identifying musculoskeletal symptoms. Sociodemographic characteristics were also recorded. Results: Results indicated that 69.4% of participants reported daily smartphone use ranging from 3 to 5 hours. A significant proportion of students experienced sleep-related problems (58.3%), eye strain (53.1%), and neck pain (46.6%). The mean IAT score indicated a moderate level of internet addiction (50.19/95), which was inversely correlated with sleep quality. CMDQ findings highlighted that discomfort was most prevalent in the right upper extremity, followed by the neck and back regions. These outcomes were strongly associated with prolonged screen exposure, poor posture, inadequate ergonomic conditions, and low levels of physical activity. Conclusion: The findings underscore the multifaceted negative impact of excessive digital media use on both physical and sleep health in university students. Preventive strategies such as promoting ergonomic awareness, encouraging routine physical activity, and implementing screen-time management interventions are essential to mitigate these health risks and enhance student well-being.
