Some Sleep Drugs Do More Than Make You Sleep
The United States Food and Drug Administration(FD
A)has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders.It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs.
Last Wednesday,the FDA announced that some of these drugs can have unexpected and dangerouseffects.These include the risk of life-threatening allergic（过敏性的）reactions.They also include rareincidents of strange behavior.These include people cooking food,eating and even driving while asleep.The patients later had no memory of doing these activities while asleep.
Last year,a member of the United States Congress said he had a sleep-driving incident.PatrickKennedy , a representative from Rhode Island,crashed his car into a security barrier near the building wherelawmakers meet.The accident happened in the middle of the night and no one was hurt.Mr.Kennedy saidhe had earlier taken a sleep medicine.He said he was also being treated with a stomach sickness drug thatcan cause sleepiness.
The FDA did not say in its announcement how many cases of sleep-driving it has documented.However,the New York Times reported last year about people who said they had strange sleep events after taking the drug Ambien.Some reported sleep-driving and sleep-walking.Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep.But they had no memory of carrying out the activities.
An FDA official says that these serious side effects of sleep disorder drugs appear to be rare.But,he also said there are probably more cases than are reported.He said the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs.The FDA has advised drug companies to carry out studies to investigate the problem.
After taking the drug Ambien,some people______.
A.are unable to drive
B.don't know how to cook
C.suffer from eating problems
D.fall asleep while walking

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 re-freshed 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 cau-tioned 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 ques-tionaires,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 Kripke 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 survey showed that people who habitually______each night have a higher risk of dying.
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
F.sleeo more than 8 hours
