The impact of light intensity during night shifts on circadian adaptation

每年，夜间工作导致的睡眠不足和生物钟紊乱给澳大利亚经济造成了20 - 30亿美元的损失，包括生产力下降、幸福感受损和健康状况不佳。目前的规定限制夜班最多连续4次。然而，最近的研究表明，这种全面限制可能是一种善意的政策，但信息不足。因此，我们可能会在不经意间增加，而不是减少与工作有关的疲劳。该项目将确定在某些工作场所，较长的夜班序列是否会减少睡眠不足和生物钟紊乱。该项目将为澳大利亚轮班工人提供更细致的疲劳调节方法和更安全的工作场所的证据基础。

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.
