Office lighting experiment suggests workers sleep longer when exposed to more daylight 办公室照明实验表明，员工在日光下工作时间越多，睡眠时间越长 A team of researchers affiliated with several institutions in the U.S. has found that office workers sleep more hours each night when exposed to more sunlight during the day. In their paper published in the International Journal of Environmental Research and Public Health, the group describes their experiments in real office buildings and what they learned from them. 隶属于美国多个机构的一组研究人员发现，上班族在白天暴露于更多阳光下时，每晚就会睡更长时间。该小组在《国际环境研究与公共卫生杂志》上发表的论文中，描述了他们在真实办公楼中进行的实验以及他们从中得出的结论。 Prior research has shown that when office workers are exposed to minimal natural light during their shifts, they tend to sleep less at night than people who are exposed to more sunlight during the day—they also tend to perform less well on cognitive tests. Prior research has also shown that children exposed to more sunlight during the day tend to sleep longer than those who see little daylight. In this new effort, the researchers sought to learn more about the sunlight/sleep connection by carrying out an experiment in two adjacent offices in an office building in Durham, North Carolina. |
