共用题干SleepingPeople who sleep for more than eight hours a night do not live as long as those who sleep for six hours,according to the biggest study yet into sleep patterns and mortality（死亡率）.Scientists have no explanation for the findings and do not know if they mean people who like a lie-in（睡懒觉）can extend their lives by sleeping less.Although it is a common belief that sleeping for at least eight hours a night is vital forhealth and well-being,the six-year study involving more than 1.1 million Americans older than 30 found that those who slept for less than eight hours were far from doing themselves any long-term harm."Individuals who now average 6.5 hours of sleep a night can be reassured that this is a safe amount of sleep.From a health standpoint,there is no reason to sleep longer,"said Daniel Kripke , a professor of psychiatry（精神病学）at the University of California, San Diego.Dr. Kripke said,"We don't know if long sleep periods lead to death.Additional studies are needed to determine if setting your alarm clock earlier will actually improve your health."The scientists,who were funded by the American Cancer Society,found that the best survival rates were among the men and women who slept for seven hours a night.Those who slept for eight hours were 12 per cent more likely to die during the six-year period of the study,when other factors such as diet and smoking were taken into account.Even those who spent a mere five hours a night in bed lived longer than those who slept eight or more hours.However,an increasing death rate was found among those who slept for less than five hours.Dr. Kripke said,"Previous sleep studies have indicated that both short-and long-duration （持续时间）sleep had higher mortality rates. However, none of those studies were large enough to distinguish the difference between seven and eight hours a night,until now." Sleeping for less than 5 hours each night is better than sleeping for 5 hours.A:Right B:Wrong C:Not mentioned
共用题干More Than 8 Hours Sleep Too Much of a Good ThingAlthough the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night. He added that it might be a good idea for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.Previous studies have shown the potential dangers of chronic shortages of sleep,for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionnaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview,Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed."It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake,"he said.To get a good night's rest,people may not need to______.A:fall asleep againB:become more energetic the following dayC:sleep less than 7 hoursD:confirm those serious consequencesE:suffer sleep problemsF: sleep more than 8 hours
