A full night’s sleep’/Not everyone needs it. The truism that all adults need at least eight hours of sleep a night for good health should be put to rest by mounting evidence that less may be better.①
People who sleep about seven hours a night live the longest, three huge studies have found, the newest out in the February issue of the journal Sleep. Still, many sleep experts say lots of adults get too little rest, and that can lead to dangerous health problems.
In the latest report from Japanese researchers, 104,010 adults were followed for about 10 years. At the start the participants answered questionnaires about their sleep patterns and about their health mental health and lifestyle habits, which also can affect survival. After accounting for all of these factors, adults getting all average of seven hours had the lowest death rates. Surprisingly, less sleep ,even as little as four hours a night, didn’t significantly increase deaths for men and only lowered survival for women if they averagde less than four hours② But adults who slept longer than seven hours, particulary women, were more likely to die during the 10 years.
Two other major published studies and a dozen smaller ones came to similar conclusions, says psychiatrist Daniel Kripke, a sleep researcher at the University of California-San Diego School of Medicine. Doctors shouldn’t tell all of their patients to get at least eight hours of sleep, he says in an editorial in the journal. Hormonal changes triggered by darkness or other unknown biological effects from long sleep could be affecting survival,③ Kripke,says.
But short sleepers may suffer other bad effects. In his brief studies, those sleeping four to five and a half hours did poorly on tests that measure memory, clear thinking and the ability to pay attention, "and they did progressively worse as the week went on," says David Dinges of the University of Pennsylvania School of Medicine. Adults who slept about seven hours performed best, he says. Other small studies have found adults who sleep less than six hours may be at higher risk for some diseases like diabetes and overweight. And sleep deprivation also causes car crashes, Dinges says. "People should get as many hours sleep, p as they need to feel rested," Kripke says, adding that there’s no proof that shortening sleep will lengthen life. s1eep need is partly genetic and may be determined by other factors that also influence life span, he says.
Which of the following statements can be inferred from the passage?
选项
A、Women are more likely to die from inappropriate sleep.
B、Less sleep shortens the life span of both men and women.
C、Generally speaking, women need more sleep hours than men.
D、Longer sleep is more harmful to men.
答案
A
解析
推理判断题。根据原文第三段的最后部分可总结出:睡得少会缩短女性寿命,但是对男性寿命没有太严重的影响;睡得多对男女都有影响,而且对女性的影响更大。由此可推断女性更可能会死于睡眠不足,故A 正确。
