F. Oversleeping — 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. ______

Previous studies have shown the potential dangers of chronic(慢性的) 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.

4. ______

For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how mush 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 tiredness interfere with day-to-day functioning.

5. ______

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.

Susan Williams went to a boarding（寄膳宿）school. Here is one of the letters she wrote to her parents from the school.

Dear Mom and Dad，

I’m afraid I have some very bad news for you. I have been very naughty and the school headmaster is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.

The trouble started last night when I was smoking a cigarette in bed. This is against the rules, of course. We are not supposed to smoke at all.

As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste­paper basket, which caught fire. There was a curtain near the waste­paper basket which caught fire, too. Soon the whole room was burning. The headmaster phoned for the fire department. The school is a long way from the town and by the time the firefighters arrived, the whole school was in flames. Many of the girls are in the hospital.

The headmaster says that the fire was all my fault and you must pay for the damage. She will send you a bill for about a million dollars.

I am very sorry about this.

Much love, Susan.

Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences(后果).

Researchers at the University of California in San Diego found that people who sleep 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 in falling asleep and feeling refreshed（恢复体力）after a night’s sleep than 8-hour sleepers.

These findings, which Dr. Daniel Kriple reported in the journal Psychosomatic Medicine, shows that people who want to get a good night’s rest may not need to sleep more than 8 hours each 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 reminded that research is needed to prove this.

Previous studies have shown the hidden dangers of lack of sleep for a long time—for instance, one report showed that people who usually 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 (问卷), in which participants(参与者) 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, waking up early in the morning and being unable to fall back to sleep, and feeling tired with day-to-day functioning（运转）.

Kripke found that people who slept between 9 and 10 hours each night most probably report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that longer 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 deal with insomnia（失眠）is to spend less time in bed. “It means that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake,” he said.
