睡眠剥夺对健康的负面影响已经得到了很好的证实，而电力的供应可能会使人们推迟睡觉时间，而不会补偿早上的睡眠时间延长，这激发了人们对研究睡眠模式可能类似于工业化前状态的社区的兴趣。在这里，我们描述的睡眠和活动在两个相邻的社区，一个城市（米兰热）和农村（Tengua），在莫桑比克的一个地区，城市化是一个持续的过程。这两个社区在日常活动和光照的数量和时间上有所不同，在米兰热镇，晚睡觉时间（101小时）与更多的晚上和更少的白天光照有关。与以前比较有电和无电社区的报告相反，Milange（7.28小时）和Tengua（7.23小时）之间的睡眠时间没有差异。值得注意的是，计算出的睡眠质量在农村Tengua比在Milange显着较差，睡眠质量差与农村地区的一些特征有关，包括更密集的体力劳动和更不舒适的睡眠安排。因此，虽然我们的数据支持电力延迟睡眠时间的假设，但城市人口的较高睡眠质量也表明工业化的某些方面对睡眠有益。
The well-established negative health outcomes of sleep deprivation, and the suggestion that availability of electricity may enable later bed times without compensating sleep extension in the morning, have stimulated interest in studying communities whose sleep pattern may resemble a pre-industrial state. Here, we describe sleep and activity in two neighbouring communities, one urban (Milange) and one rural (Tengua), in a region of Mozambique where urbanisation is an ongoing process. The two communities differ in the amount and timing of daily activity and of light exposure, with later bedtimes (≈1 h) associated with more evening and less daytime light exposure seen in the town of Milange. In contrast to previous reports comparing communities with and without electricity, sleep duration did not differ between Milange (7.28 h) and Tengua (7.23 h). Notably, calculated sleep quality was significantly poorer in rural Tengua than in Milange, and poor sleep quality was associated with a number of attributes more characteristic of rural areas, including more intense physical labour and less comfortable sleeping arrangements. Thus, whilst our data support the hypothesis that access to electricity delays sleep timing, the higher sleep quality in the urban population also suggests that some aspects of industrialisation are beneficial to sleep.
