Lack of sleep

1.Getting less sleep has become a bad habit for most American kids.

2.According to a new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 p.m.or later on school nights, even though they have to get up early.  

3.Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

4.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours.  

5.For most school-age children, ten hours is ideal. But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours.  

6.And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

7.“More children are going to bed with TVs on, and there are more opportunities to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School.  

8.She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical.  

9.Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 p.m.

10.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to.  

11.Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 a.m. to 8:30 a.m. Students, parents and teachers are pleased with the results.

睡眠不足

1.睡眠不足已经成为大多数美国孩子的坏习惯。

2.根据美国国家睡眠基金会的一项新调查，51%的10岁至18岁的孩子在上学的晚上10点或更晚才睡觉，尽管他们必须早起。

3.去年，该基金会报告称，近60%的7至12岁儿童表示他们白天感到疲倦，15%的人表示他们在学校睡着了。

4.你需要多少睡眠在很大程度上取决于你的年龄。婴儿需要大量的休息:他们中的大多数人每天睡大约18个小时!成年人大约需要8小时。

5.对于大多数学龄儿童来说，10个小时是理想的。但美国国家睡眠基金会的最新调查发现，35%的10至12岁儿童每天只睡7到8个小时。

6.猜猜近一半的受访孩子说他们睡前做什么?看电视。

7.布朗大学医学院的睡眠研究员玛丽·卡斯卡顿博士说:“越来越多的孩子开着电视上床睡觉，他们有更多的机会保持清醒，有更多的家庭作业、互联网和电话。”

8.她说，这些睡前活动会让孩子们非常兴奋，让他们很难平静下来睡觉。其他专家表示，部分问题在于化学物质。

9.被称为激素的身体化学物质水平的变化不仅使青少年的身体发展出成年人的特征，而且使青少年在晚上11点之前很难入睡。

10.由于困倦对青少年来说是一个严重的问题，一些学区已经决定将高中的上课时间推迟。

11.三年前，明尼苏达州伊迪纳的学校将上课时间从早上7点25分改为早上8点30分。学生、家长和老师都对结果感到满意。
