Each year, the sleep loss and body clock disruption caused by night work cost the Australian economy $2–3 billion in lost productivity, impaired well-being, and poor health. Current regulations limit sequences of night shifts to a maximum of four in a row. However, recent research suggests that this blanket limit may be a well-intentioned, but ill-informed, policy. As a result, we may be inadvertently increasing, rather than reducing, work-related fatigue. This project will determine whether longer sequences of night shifts may reduce sleep loss and body clock disruption in some workplaces. The project will provide the evidence base for a more nuanced approach to fatigue regulation and a safer workplace for Australian shiftworkers.

每年，夜间工作造成的睡眠不足和生物钟紊乱使澳大利亚经济损失了20亿至30亿美元的生产力损失，损害了福祉和健康状况。目前的规定限制夜班的顺序，最多连续四个。然而，最近的研究表明，这种全面限制可能是一种善意的，但不明智的政策。因此，我们可能会无意中增加，而不是减少，与工作有关的疲劳。该项目将确定更长时间的夜班是否可以减少某些工作场所的睡眠不足和生物钟干扰。该项目将提供证据基础，为澳大利亚轮班工人提供更细致入微的疲劳监管和更安全的工作场所。
