Summary
Shift work is commonly regarded as work that extends outside the daylight hours. “Shift work” commonly denotes those work schedules that divide 24 hours in a day into roughly equal sized time schedules which will be covered by different teams in sequence. Work hours that displace sleep to the daytime and work to the night time interferes with the circadian and homeostatic regulation of sleep. In about 5 to 10 percent of night-shift workers, the sleep-wake disturbance is severe enough to warrant diagnosis as shift-work sleep disorder, which is characterized. Shift work disorder is the presence of excessive day time sleepiness and insomnia affecting people whose work hours overlap with the typical sleep period. Our objective was to estimate the prevalence of symptoms of shift work disorder and the factors associated with it among hospital staff in a tertiary care hospital in Bangalore, India.
