Effects of Sleep Patterns on Mental Health Among Nurses

Sleep plays a vital role in maintaining psychological resilience and cognitive function, particularly among healthcare professionals such as nurses who are frequently exposed to shift-based work schedules. This study explores the relationship between sleep patterns and mental health outcomes among nurses working in tertiary care hospitals in Lucknow, India. Using a cross-sectional design, data were collected from 44 registered nurses through validated instruments: the Pittsburgh Sleep Quality Index (PSQI) and the Depression Anxiety Stress Scale (DASS-21). Results indicated a high prevalence of poor sleep quality, especially among those assigned rotating and frequent night shifts. Nurses reporting reduced sleep duration—often below four hours per night—also experienced elevated symptoms of stress, anxiety, and depression. The study found significant associations between specific sleep disturbances (e.g., difficulty initiating sleep, daytime drowsiness) and psychological distress. These findings highlight the urgent need for evidence- based policy interventions, including shift restructuring, mental health support services, and sleep hygiene education to safeguard nurse well-being and ensure high-quality patient care.
