在建筑工地上因施工需要,常有一批工人要上夜班。由于人们习惯于白天工作和学习,晚上休息和睡眠,于是就形成了所谓的“昼夜节律”。有的人偶尔加夜班,感到工作效率不高,主要是因为不能适应新的时间规律。事实上,人脑中的“生物钟”有较大的可塑性,许多工人上夜班习惯了,身体同样健康,效率也不低,这就说明人们能够适应改变了的时间规律。 Due to construction needs on the construction site, often a group of workers to night shift. As people are accustomed to working and studying during the day, resting and sleeping at night, so-called “circadian rhythms” are formed. Occasionally, some people add night shift, feeling that the work efficiency is not high, mainly because they can not adapt to the new law of time. In fact, the “biological clock” in the human brain has greater plasticity. Many workers are accustomed to work on the night shift and are equally healthy and inefficient. This shows that people can adapt to changing time laws.
