Shift work is increasingly used in industry and services; in the Norwegian offshore industry approximately 6750 employees work night shifts. We wanted to look into the implications of night shifts on sleep and circadian rhythm, with particularly focus on the offshore sector.
We conducted literature searches on Medline, covering the period from 1966 to 2003; only eight studies pertaining to the offshore activity in the North Sea with emphasis on sleep and night work were identified.
Night shifts on oil platforms were associated with sleeping difficulties. The isolated setting on the installations in the North Sea probably facilitates biological adaptation to night work compared to work onshore. Light therapy has a documented effect for re-adaptation to normal daytime functioning upon returning home.
Night work disturbs sleep. The level of functioning during the first night shifts is probably lower than the optimal level of functioning. Only a few studies of adaptation to night work in the offshore industry have been conducted and little research has been done concerning swing shifts in the North Sea. The field is obviously in need of more empirically based knowledge.
轮班工作在工业和服务业中越来越普遍；在挪威近海工业中，约有6750名员工从事夜班工作。我们希望研究夜班对睡眠和昼夜节律的影响，尤其关注近海部门。
我们在Medline上进行了文献检索，涵盖1966年至2003年期间；仅发现八项与北海近海活动相关、重点关注睡眠和夜间工作的研究。
石油平台上的夜班与睡眠困难有关。与岸上工作相比，北海设施的孤立环境可能有助于对夜间工作的生物适应。有文献记载，光疗法对回家后重新适应正常白天功能有效果。
夜间工作会干扰睡眠。首次夜班期间的工作水平可能低于最佳工作水平。关于近海工业中对夜间工作的适应，仅进行了少数研究，而关于北海倒班的研究则很少。该领域显然需要更多基于实证的知识。
