What is Shift Work Disorder (SWD)?

Shift Work Disorder is a specific circadian rhythm sleep disorder that occurs when an individual’s internal body clock, which regulates sleep-wake cycles, clashes with their work schedule. This misalignment can lead to difficulty falling asleep, staying asleep, and achieving restful sleep during the designated sleep hours. SWD is particularly prevalent among individuals who work rotating shifts, night shifts, and early morning shifts.
