Shift work sleep disorder is a condition that affects people who work non-traditional hours, such as night shifts or rotating shifts. This disruption in the body's natural sleep-wake cycle can lead to difficulties in falling asleep, staying asleep, or waking up too early. Individuals with this disorder often experience excessive sleepiness during waking hours, which can impact their daily activities and overall health. Symptoms may include insomnia, fatigue, and difficulty concentrating, making it essential for affected individuals to seek strategies to improve their sleep quality and manage their work schedules effectively.
