Shift work 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 circadian rhythm can lead to difficulties in sleeping, staying awake, and overall health. Symptoms may include insomnia, excessive sleepiness, and difficulty concentrating. Individuals with shift work disorder may also experience mood changes and increased risk of chronic conditions like heart disease and diabetes. Treatment options often include lifestyle changes, such as improving sleep hygiene, and in some cases, medication to help manage symptoms and improve overall well-being.
