Shift Work Disorder
What is Shift Work Disorder?
Shift Work Disorder occurs when you have difficulties adjusting to a work schedule that takes place during a time when most people sleep. When you have Shift Work Disorder, there is a conflict between your body’s circadian rhythms and your work schedule. You may have to be at work when your body wants to sleep. Then when you have to sleep, your body expects to be awake.
How does shift work effect your health?
People with Shift Work Disorder may sleep up to four hours less than the average worker. Shift Work Disorder causes you to have trouble sleeping or be severely tired. The quality of sleep may be poor, and you may wake up feeling fatigued or exhausted. This can hurt your performance at work, and can put you at risk for making a costly mistake or getting injured on the job.
Not everyone who does shift work has Shift Work Disorder. Many people have difficulty initially adjusting to a new shift. If after several weeks you have difficulty falling asleep or staying asleep, or you feel tired even after sleeping 7-8 hours, you may have Shift Work Disorder.
What are the Symptoms of Shift Work Disorder?
The symptoms of Shift Work Disorder usually last as long as you keep the shift work schedule. The sleep problems tend to go away once you begin sleeping at a normal time again. Some people may have sleep problems even after the shift work schedule ends.
Shift Work Disorder is a circadian rhythm sleep disorder. Your circadian rhythms are your body’s internal clock that signals when you are supposed to feel sleepy or alert. Your circadian rhythms operate on a roughly 24-hour schedule. Your body uses sunlight to determine how much of the sleep-promoting hormone melatonin it produces. In shift work disorder, melatonin production may occur when you need to be awake and alert for your job. Exposure to sunlight may prevent you from producing melatonin when you are supposed to sleep.
There are several variations of shift work schedules that can cause difficulties.
- Early-morning shifts
- Night shifts
- Overnight shifts
- Rotating shifts
Some people have a more difficult time with certain shift work schedules. Night owls may adjust more easily to working an evening shift than morning-types. Likewise, morning larks may have an easier time with early morning shifts. Many people have difficulty adjusting to overnight or rotating shifts.
