　　Back-to-School Means Adjusting Kids Sleep Clocks

　　SUNDAY, Aug. 20 (HealthDay News) -- Along with getting newschoolsupplies and clothing, re-establishing childrens sleephabitsshould be on parents back-to-school to-do lists.

　　据美国“每日健康新闻”网站8月20日报道，在新学期开始之前，家长们不仅需要为孩子准备好新的学习用品和服装，还应当帮助他们将睡眠习惯重新调整到上学时的状态。

　　Children tend to go to go to bed and wake up later duringthesummer, and altering this cycle can be difficult, note expertsatthe University of Florida, Gainesville. Parents should try togettheir children back into a school-year sleeping schedule atleastone or two weeks before classes start, said Dr. Anne-MarieSlinger,assistant professor of pediatrics, UF College ofMedicine.

　　美国佛罗里达州大学专家们表示，孩子们在夏季往往会晚睡晚起，要想改变这种作息时间是一件困难的事。该大学医学院的儿科医学助理教授安妮·玛莉·斯林格尔表示，父母应在距离开学一到两周时将孩子的睡眠时间恢复到上学时的状态。

　　If a child isnt properly prepared and doesnt get enoughsleep,it can really affect their school performance.

　　如果孩子没有准备好开学并导致睡眠不足的话，他们在学校的表现将会受到影响。

　　Sleep deprivation can have a pretty significant effectonconcentration, memory and even mood. If a child ischronicallysleep deprived, its far more difficult for them toparticipate inclassroom activities and learn new things. If theyretired, theywont be engaged, Slinger said in a preparedstatement.

　　斯林格尔在一份声明中指出：“睡眠不足会让孩子在课堂上的注意力、记忆力甚至情绪都受到严重影响。如果一个孩子长期处于睡眠不足的状态，他将很难参与到课堂活动和学习新知识当中。如果孩子们感觉累，他们将不可能全身心投入到学习中去。”

　　In general, children require at least nine hours ofuninterruptedsleep to be ready for learning.

　　一般说来，孩子至少需要连续睡上9个小时才能为学习做好准备。

　　Establishing a regular sleep schedule also makes it easiertochildren to wake up in order to have enough time to have ahealthybreakfast, another important factor in schoolperformance.

　　另外，有规律的睡眠也方面孩子起床后有充足的时间吃一顿健康的早餐，这也是影响他们在校内表现的另一个重要因素。

　　To help them prepare for a new school year, its importanttotalk to kids so they know what to expect and to familiarizethemwith their daily schedule before the school year begins. Therearea lot of things parents can do to ease that transition backtoschool, Slinger said.

　　斯林格尔说：“为帮助孩子们适应新学期，父母们与孩子进行一次交谈会很重要，孩子可以因此在开学之前熟悉日常作息时间。父母们可以采取很多种办法来帮助孩子们轻松返回校园。”

　　For example, parents can schedule activities -- such asbrushingteeth, taking a bath, or reading a story -- that assistthetransition to bedtime.

　　例如，父母可以通过安排诸如刷牙、洗澡或朗读故事等方法来帮助孩子及时就寝。（实习编辑：顾萍）
