What is shift work sleep disorder?

Shift work sleep disorder is trouble sleeping because you work nights or rotating shifts. You also may have this problem if you have trouble staying awake or alert when you are supposed to work your shift. You may not be able to sleep during the day, and you may not feel rested with the sleep you do get.

Shift work sleep disorder involves a problem with your body’s 24-hour internal clock, or circadian rhythm. Light and dark help your body know when to be active and when to rest. Light is a cue to be awake, while dark tells your body to sleep. When you work at night and sleep during the day, your body’s internal clock needs to reset to let you sleep during the day. Sometimes that’s hard to do.

This sleep disorder usually is a problem for people who work all night. But people who work an early morning shift-for example, starting at 4 a.m.-also may have sleep problems. Rotating shift work also can be hard. In these shifts, people work the day shift on some days and the night shift on others.
