[2024·江苏省无锡市质量调研测试]Insomnia (失眠) feels like a curse for those left tossing and turning as they try to fall asleep. Such problems can be not only upsetting, but also harmful to the brain, as revealed in last issue's article on sleep.

Scientists from the US University of Washington have been using bracelets (手镯) to monitor the sleep patterns of 507 university students over a period of three years. The bracelets allowed scientists not only to monitor the sleep patterns of their subjects but also to examine their exposure to light during the day.

The data revealed that the students enjoyed about the same quantity of sleep regardless of seasons. But on weeknights in the winter they went to bed 35 minutes later, and also rose again 27 minutes later, compared with weeknights in the summer.

The discovery surprised the scientists. The city of Seattle, where the university is located, gets 16 hours of daylight in the summer and only 8 in the winter. They expected that long light summer evenings would keep the students up longer—but the opposite proved to be the case.

According to the scientists, the explanation may be that the low quantity of daylight in winter disturbs the students' internal clock, shifting it by some 40 minutes. They simply spent too little time outdoors during winter months.

The scientists also suggest that the type of light matters very much. “Light during the day, particularly in the morning, affects your internal clock, so you get tired earlier in the evening, while light late in the day or early in the evening delays your tiredness” explains Horacio, Professor of Biology at the University of Washington and one of the scientists behind the publication.

According to him, the results are an important reminder to all of us, not just American university students, to think about light levels and our exposure. “Many of us live in cities with lots of artificial light, and at the same time our lifestyle keeps us indoors during the day” Horacio notes. “The study demonstrates that we have to step outside—even briefly, and particularly in the morning—to be subjected to natural light.”
