More Than 8 Hours Sleep Too Much of a Good Thing
1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
2 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.
3 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.
4 Previous studies have shown the potential dangers of chronic shortages of sleep一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.
5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionaires,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.
6 Kridke found that people who slept between 9 and 10 hours each night were more like-ly 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.

One of the sleep problems is waking in the middle of the night,unable to______.
A: fall asleep again
B: become more energetic the following day
C: sleep less than 7 hours
D: confirm those serious consequences
E: suffer sleep problems

Sleeplessness

Insomnia or sleeplessness is a common complaint of women as they enter into menopause.Insomnia
means having trouble falling asleep or staying asleep or the feeling that your sleep was not adequate for you.
For women who are having night sweats,their sleep is broken by frequent awakening and therefore not re-
freshing. Generally once the night sweats are controlled a normal sleep pattern returns.If it doesn't it may
be,or have become chronic insomnia. How do you know?
If you suffer from insomnia every night or most nights for a period of one month then you have chronic
insomnia.If you're not having night sweats then it's time to look for other causes of sleeplessness. Depression
and anxiety disorders are the most common causes of chronic insomnia. If you feel depressed you need to be
checked by a qualified health care provider. Movement disorders such as restless leg syndrome are second on
the list of insomnia for them,there are new medicines that may help.Other common causes are shift work-
ing,and pain.
In up to 30%of people with chronic insomnia no cause can be identified.Medical treatment of these
people has generally been with sleeping pills.It is estimated that 25% of the adult population in America
took some type of medicines for sleep last year. It is generally agreed that sleeping pills should only be in the
lowest dose and for the shortest possible time.
Sleep hygiene is directed at changing bad sleep habits.The recommendations are：一Go to bed only
when sleepy. Do not wait up to a specilized time. Avoid caffeine and alcohol in the evening,etc.

How many possible causes of sleeplessness are mentioned in the second paragraph?
A:Five.
B:Six.
C:Seven.
D:Numerous.

College Night Owls Have Lower Grades
College students who are morning people tend to get better grades than those who are night owls（晚睡的人）,according to University of North Texas researchers.
They had 824 undergraduate（大学本科生的）students complete a health survey that includ-ed questions about sleep habits and daytime functioning,and found that students who are morning people had higher grade point averages(GPAs)than those who are night people.
"The finding that college students who are evening types have lower GPAs is a very important finding,sure to make its way into undergraduate psychology texts in the near future,along with the research showing that memory is improved by sleep,"study co-author Daniel J.Taylor said in a prepared statement.
"Further,these results suggest that it might be possible to improve academic performance by using chronotherapy（时间疗法）to help students retrain their biological clock to become more morning types,"Taylor said.
The research was expected to be presented Monday at SLEEP,the annual meeting of the As-sociated Professional（专业的）Sleep Societies ,in Baltimore.
In other findings expected to be heard at the meeting,University of Colorado researchers found a significant association between insomnia（失眠）and a decline in college students' aca-demic performance.
The study included 64 psychology,nursing and medical students,average age 27 .4 years,who were divided into two groups-low GPAs and high GPAs.
Among those with low GPAs,69 .7 percent had trouble falling asleep,53 .1 percent experi- enced leg kicks or twitches（痉挛）at night,65. 6 percent reported waking at night and having trouble falling back to sleep,and 72 .7 percent had difficulty concentrating during the day.
"In college、students,the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom,"study author Dr. James F. Pagel said in a prepared statement."This study showed that disordered sleep has significant harmful effects on a student's academic performance,including GPAs."

In the second study,students with low GPAs did NOT complain of______.
A: having trouble falling asleep
B: waking at night and having trouble falling back to sleep
C: having difficulty concentrating during the day
D: being kicked in the leg at night

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.

More Than 8 Hours Sleep Too Much of a Good Thing

Although 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.
