Shift work disorder is a chronic condition that is directly related to a person’s work schedule. Shift work disorder is considered a “circadian rhythm sleep disorder” by the International Classifications of Sleep Disorders—meaning there is a misalignment or de-synchronization in sleep patterns. With shift work disorder, you have a hard time sleeping when sleep is desired, needed, or expected.
