nattskift

Nattskift, or night shift, denotes work scheduled predominantly at night. It is used in industries that require around-the-clock operations, such as healthcare, transportation, manufacturing, security, and public services. Night shifts often run outside standard daytime hours, with common patterns including 8- or 12-hour blocks that cover late-evening to early-morning hours.

Many organizations use rotating schedules, moving workers from night to day to reduce prolonged night exposure; forward-rotating schedules are favored for circadian alignment.

Working nights disrupts natural circadian rhythms, reducing sleep duration and quality; fatigue, daytime sleepiness, and impaired alertness can affect performance and safety. Long-term exposure has been linked in studies to increased risks for sleep disorders, metabolic issues, cardiovascular disease, and mental health concerns, though results vary by rotation, sleep opportunity, and individual chronotype.

In many places, night work commands higher pay or bonuses; however, it can strain family life, social activities, and childcare. Some prefer night work due to daytime obligations, while others experience social isolation.

Legislation and collective agreements govern max hours, rest periods, and health surveillance; employers typically provide fatigue management, rest facilities, and access to health services.

Nattskift remains essential for many sectors but presents challenges for workers' health and well-being; research emphasizes the importance of supportive scheduling and health monitoring.
