Shift work sleep disorder (SWSD) is a circadian rhythm sleep disorder characterized by insomnia and excessive sleepiness affecting people whose work hours overlap with the typical sleep period.
Shift work is an employment practice designed to make use of, or provide service across, all 24 hours of the clock each day of the week. The practice typically sees the day divided into shifts, set periods of time during which different groups of workers perform their duties. The term shift work includes both long-term night shifts and work schedules in which employees change or rotate shifts. In medicine and epidemiology, shift work is considered a risk factor for some health problems in some individuals, as disruption to circadian rhythms may increase the probability of developing cardiovascular disease, cognitive impairment, diabetes, and obesity, among other conditions.
