Individualised predictions of circadian timing, sleep, and performance

当我们感到困倦或警觉时，人体的24小时时钟会进行调节。在倒班工人中，睡眠和节奏被打乱会导致疲惫和代价高昂、往往是致命的工作场所事故。现有的测量生物钟计时的方法成本高昂，对于操作设置不切实际，并且不能实时工作。利用轮班工作者群体，这个项目将开发出准确预测个人身体时间、睡眠/醒来模式和表现的模型，只需要一个简单的活动/光传感器和对生物钟对光的敏感度的评估。这种新模式将彻底改变疲劳管理，并为数百万倒班工人创造更安全的工作环境。

The body's 24-hour clock regulates when we feel sleepy or alert. In shift workers, disrupted sleep and rhythms leads to fatigue and costly, often deadly, workplace accidents. Existing methods for measuring body clock timing are costly, impractical for operational settings, and do not work in real time. Using a shift-worker population, this project will develop models that accurately predict body timing, sleep/wake patterns, and performance for an individual, requiring only a simple activity/light sensor and an assessment of the body clock's sensitivity to light. The new model would revolutionise fatigue management and make safer work environments for millions of shift workers.
