Shift Work, Sleep and Well-Being: A Qualitative Study on the Experience of Rotating Shift Workers

This study critically investigates the impact of sleep deprivation on the well-being of shift workers in a Mumbai-based manufacturing facility, highlighting a significant yet often overlooked occupational health concern. Employing a robust, two-phase mixed-methods approach, phase 1 quantitatively assessed the sleep patterns, quality and daytime sleepiness of 85 shop floor workers using sleep diaries, Fitbit wristbands, Actigraphy and validated tools such as the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index. Phase 2 comprised in-depth qualitative interviews with 14 workers experiencing poor sleep, alongside interviews with four plant managers and family members. Thematic analysis of the interview data revealed a compelling narrative: shift work fundamentally disrupts circadian rhythms, precipitating irregular sleep patterns, chronic sleep deprivation and a marked decline in workers’ physical and psychological well-being. The study also identifies effective strategies to mitigate the adverse effects of shift work. It contributes valuable insights, proposing a framework for future studies to develop targeted, evidence-based interventions that address the critical issue of sleep deprivation among shift workers.
