Abstract:
Sleep and wakefulness are physiological processes in our lives that are regulated by circadian
rhythms. The level of melatonin, the "sleep hormone", increases with the onset of darkness, and
its production slows down in the morning. Exposure to artificial light at night disrupts our circadian
rhythm and the processes it controls. Shift work is when an individual works from 9 am to 5 pm.
But the night shift refers to the time when a group of workers who work at night in factories and
enterprises work in the evening or at night, especially from 4 p.m. to 8 a.m. according to a regular
schedule. One in five people in industrialized countries work night shifts, and studies in America and
Europe show that between 15 and 30% of adult workers have some form of shift work. Between 10%
and 30% of shift workers meet the diagnosis of shift work disorder (SWD). 5-10% of shift workers experience severe shift insomnia and sleepiness. At least ¾ of shift workers suffer from insomnia.
Excessive sleepiness usually occurs during shifts (mainly at night) and is associated with impaired
cognitive ability due to the need for sleep and reduced alertness, and decreased alertness reduces
performance. Job performance is influenced by many workplace environmental factors, including
workload, coworker relationships, stress levels, and extended hours. A nurse specialist provides
nursing care by monitoring and evaluating 24 hours a day, and by working night shifts, the circadian
system of sleep is disturbed, causing sleep problems and insomnia. When examining how night shift
work affects nurses' ability to concentrate, the decline in concentration (33.3%) was twice as high as
that of day shift nurses (16.7%). found that shift nurses who worked the night shift had higher rates of insomnia and chronic fatigue compared to nurses who stopped working the night shift. Lack of sleep
manifests as a decline in cognitive functions such as attention, decision making, and reaction time.
These cognitive and functional declines can negatively affect quality of life and lead to impaired job
performance. An Australian study by Winwood et al found that fatigue associated with night shifts
increases the risk of human error and injury, and negatively affects the quality of patient care. Lack of sleep significantly affects nurses' alertness, concentration, and job performance. This review article
discusses the relation between shift work-related sleep and job performance based on international
research findings.
