Place and duration of study: The study was conducted at Pakistan Ordinance Factories hospital, Wah Cantt, Pakistan from September 2025 to November 2025‎. Material and Methods: The study was done on 118 nurses of a tertiary care hospital from September 2025 to November ‎‎2025. The sample was collected using convenience sampling.

The mean score of shift work disorder (SWD) ‎among the participants was 24.13 ± 7.75. A significant difference in SWD scores was observed ‎across different age groups (p value= <0.001) and duration of work (0.004), as revealed by ‎ANOVA.‎ Conclusion: ‎ Our study indicates a high prevalence of Shift work disorder among nurses of the hospital ‎emphasizing the fact that nurses employed in shifts are more prone to sleep disorders.
