Night shift work and circadian adaptation

The circadian rhythms of night shift workers do not usually phase shift immediately to adapt to their unusual work and sleep schedules. The night shift work reduces workers quality of life and produces potentially dangerous health and safety problems. The circadian rhythms misalignments result in a multitude of negative symptoms including poor work performance and reduced alertness during night work and poor daytime sleep at home This paper reviews these health and safety problems connected with circadian adaptation ability, ie the shifting of circadian rhythms to align with night work and day sleep schedules. We first describe basic principles of human circadian rhythms relevant to producing circadian adaptation to night shift work.. These principles should enable designing appropriate work/sleep-light/dark schedules for accelerating circadian adaptation in night shift workers. . We conclude this review by discussing the impact of individual differences on possible circadian adaptation. Keywords: Shift work, Circadian rhythms, Sleep disorder, Adaptation
