Introduction: Shift work is associated with impaired sleep patterns, poor quality of life (QOL), and several medical conditions. Shift work disrupts the sleep-wake cycle and biological rhythms. Poor sleep quality and disruption of the normal circadian cycle are likely to cause cardiovascular disorders, obesity, diabetes mellitus, anxiety, depression, lethargy, and fatigue. It is also associated with diminished vigilance and work performance.
Aim: The aim of the study is to evaluate the impact of shift work on quality of sleep and QOL in industrial workers.
Methodology: This is a cross-sectional, comparative study conducted on 147 rotating shift work employees and 132 regular nonshift day workers in various industries. Semi-structured pro forma was used for sociodemographic data. Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale were used to assess the quality of sleep. The WHO-5 Well-Being Index and WHOQOL-BREF were used to assess the QOL. Appropriate statistical methods were used to analyze the data.
Results: Compared with nonshift day workers, those work for variable shifts exhibited higher rates of heavy smoking and increased caffeine consumption. Variable shift workers reported persistent sleep disturbance, poor sleep quality, and daytime sleepiness compared to fixed day shift workers (P < 0.05). The overall QOL score and well-being index were also significantly (P < 0.05) low in shift workers compared to nonshift day workers.
Conclusion: Shift work has a significant negative impact on quality of sleep and QOL and results in poor functioning and disturbances in mental and physical health of the individual. Hence, attention must be paid to the strategies that can improve the quality of sleep and QOL.
