Adequate sleep and stress management are vital for nurses to maintain decisionmaking, alertness, and patient care safety. Workload, shift duties, and limited support contribute to stress and poor sleep, which may increase risk of errors, burnout, and reduced job satisfaction. This descriptive study assessed sleep quality and perceived stress among 85 Nursing Officers working in critical care units of a Govt Medical College & Hospital, Chandigarh, using standardised questionnaires (PSQI and PSS10). Results revealed that 65.1 percent of participants had poor sleep quality, 57 percent experienced moderate stress, and 3.5 percent reported high stress. A moderate positive correlation (r = 0.314, p = 0.003) was observed between poor sleep and higher stress levels. Findings highlight the importance of interventions focusing on sleep hygiene and stress management to support nurses’ well-being and ensure safe patient care.
