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 refreshing. 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 working, 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: —Go to bed only when sleepy. —Do not wait up to a specified time. —Avoid caffeine and alcohol in the evening, etc.
The word "insomnia" in the first paragraph means
A．having trouble falling or staying asleep.
B．feeling that one's sleep is adequate for him.
C．having no sweats at night.
D．having a normal sleep pattern.

It" s a time when school， homework， active social lives and part-time jobs keep teenagers （少年 ） busy from early in the morning until late at night. They are likely to try to make up for a lack of sleep by "sleeping in" on the weekends. Unfortunately， this causes irregular sleep and actually makes the problem worse.
Most teenagers are not able to fall asleep until late at night. Since many teens aren"t sleepy until around 11 p.m.， but need to be at school by 7: 30 or 8: 00 A.m.， they cannot get enough sleep. During puberty（青春期）， the biological clock in the brain naturally re-sets to a later time， and this causes teens to fall asleep later. Then， when it" s time to get up， a teen" s body clock is likely to still be producing the night-time hormones（荷尔蒙）. This makes it hard for them to feel active and energetic in the morning.
A growing body of research suggests that starting high school later improves attendance， achievements and grades. A few years ago in an important study， test scores on the SAT college entrance exams in Edina， Minnesota jumped more than 100 points on average， when the morning school bell rang an hour later. Unfortunately， most schools are not set up to start later and fail to satisfy teen"s sleep needs.
What effect does "sleeping in" on the weekends have on teenagers？ 查看材料
A.Improving their health.
B.Weakening their energy.
C.Disturbing their biological clock.
D.Making up for their hormone loss.

Now, health officials have begun a campaign to urge children to get enough sleep. The officials say children need at least nine hours o(sleep every night. They say research shows that children who get this much sleep perform. better in school, suffer fewer accidents and are less likely to become too fat.
Studies show that lack of sleep causes tiredness and problems with clear thinking. People who do not get enough sleep become angry easily and have trouble controlling their emotions.
Among children, problems that result from lack of sleep often are mistaken for more serious disorders. Unlike adults, tired children seem to have endless energy. Some doctors mistakenly identify this as hyperactivity.
Experts say many American teenagers are not getting enough sleep. Teenagers stay up later for several reasons, including schoolwork, after school activities and late- night fun. Many high school students in the United States start school very early in the morning.
