Good news for middle and high school students. When it comes to sleeping in a little longer, physicians are on your side.

有一个对初中生和高中生的好消息。当提到关于睡得时间长一点，医生是站在你们这边的。

On Monday, the American Academy Pe writes in a press release regarding its new policy statement called “School Start Times for Adolescents.” diatricsannounced its recommendation that middle and high schools start at 8:30 a.m. or later. “Doing so will align school schedules to the biological sleep rhythms of adolescents, whose sleep-wake cycles begin to shift up to two hours later at the start of puberty,” the AAP

 在星期一，美国儿科协会宣称他们推荐初中和高中学生在早上八点半或者更迟一点再开始上学。“这样做是使学校的作息表和青少年生理睡眠规律一致。他们睡着和清醒的睡眠循环以两个小时交替，当他们开始青春期的时候”，美国儿科协会在关于他们新的政策声明中向媒体透露，并将此声明名为“学校为青春期学生开始的时间”。

“An estimated 40 percent of high schools in the U.S. currently have a start time before 8 a.m.; only 15 percent start at 8:30 a.m. or later. The median middle school start time is 8 a.m., and more than 20 percent of middle schools start at 7:45 a.m. or earlier,” according to the AAP.
“在美国估计有40%的高中生经常在在早上八点开始上学，仅有15%的在八点半或者更晚开始上学。大多数的初中生在在早上八点上学，有20%的初中学校在早上七点四十五分或者更早开始”，根据美国儿科协会透露。
Many parents of teens joke that their kids would never get out of bed if it were up to them, but getting the right amount of sleep is no laughing matter.
许多青少年家长开玩笑说他们的孩子将永远不会起床，如果他们听到这个消息。但是获得充足的睡眠不是开玩笑的事。
“Chronic sleep loss in children and adolescents is one of the most common – and easily fixable – public health issues in the U.S. today,” according to Judith Owens, M.D., director of Sleep Medicine at Children’s National Health System in Washington, DC, and lead author of the policy statement, published in theSeptember 2014 issue of Pediatrics. 
“长期睡眠不足在儿童和青少年中是很常见的，并且容易修正。这成为了美国现在的公共健康问题”，根据Judith Owens, M.D，在国家卫生系统在华盛顿特区的儿童睡眠医学主任，政策声明的主要作者,发表在2014年issue of Pediatrics上的小儿科的问题。
“The research is clear that adolescents who get enough sleep have a reduced risk of being overweight or suffering depression, are less likely to be involved in automobile accidents, and have better grades, higher standardized test scores and an overall better quality of life,” Owens said in the press release. “Studies have shown that delaying early school start times is one key factor that can help adolescents get the sleep they need to grow and learn.”
“研究清楚地表明对获得充足的睡眠将减少青少年超重和抑郁的几率，并且不太会出现汽车事故，他们将会在学业上表现的更出色，获得高质量的生活”,Owens在媒体上这样说。“研究已经表明推迟学校开始的上学的时间成为帮助青少年获得他们需要的睡眠的关键因素”。
Even before the AAP’s announcement school districts across the country have been rethinking start times. Earlier this yearThe New York Times wrote about the issue and profiled the plight of Jilly Dos Santos, a student at Rock Bridge High School, in Columbia, Missouri. When Dos Santos learned that school officials were contemplating starting school at 7:20 a.m. (30 minutes earlier than the existing 7:50 am start time), she became an unlikely sleep activist. The student rallied others to her cause and she educated herself about the science of sleep. Ultimately, school officials decided against the earlier start time. And a few months later the school actually moved the start time ahead to 9 a.m., according to the article.
早在美国儿科协会宣布学校要重新思考学校开始的时间，纽约时报已经写过这样的问题，以一个在密苏里州哥伦比亚的Rock Bridge高中的学生Jilly Dos Santos的困境为报道内容。当Dos Santos得知学校官方考虑将上学的时间定于早上7:20（比以前上学的的时间早半个小时），她变得不怎么睡觉了。她开始自学关于睡眠的科学。最终学校官方决定不更改上学时间。几个月之后，学校确实将早上上学的时间改到早上九点，根据文章里要求的那样。

One of the organizations that Dos Santos reached out to for help was Start School Later, a nonprofit organization based in Annapolis, Maryland, that focuses on getting public schools to set “healthy school hours.” 

Dos Santos寻求帮助的其中一个组织是晚点上学，一个在马里兰州首府安纳波利斯的非盈利组织，他们关注将公立学校开始上学的时间调整为健康的学校作息。

“It’s going to take collective action, perhaps on a national scale, to get many districts to take on this issue,” Terra Ziporyn Snider, PhD, the executive director and co-founder of Start School Later, told Yahoo Health. 
“这即将开始集体行动，也许是全国范围内的，让许多区域关注这个事件”，Terra Ziporyn Snider博士，晚点上学 的创建者之一和首席执行官，这样告诉雅虎健康媒体的。
“The science is clear; the will to change isn’t,” she explained. “The reason for that is that community life revolves around school schedules, and any suggestion of change - earlier, later, whatever - inevitably brings powerful opposition from everyone who fears a change in routine.”
“科学是明确的，但是想要去改变的意愿并不是这样”她解释道。 “原因在于社区活动和周边学校的作息时间是相关的，任何建议去改变，早一点或是晚一点，都会不可避免地遭到那些害怕日常生活改变的人的反对。

Ziporyn Snider pointed out that many school districts have “found feasible and affordable” ways to push back start times. She recommends that anyone interested in learning more about later school start times to check out the success stories posted on the organization’s website.

Ziporyn Snider指出，许多学校都已经找到可行性的办法去推迟早上上学的时间。她推荐任何对这些事情感兴趣的人都可以上机构的网站，看看那些网上展示的成功的故事。

Getting enough sleep is of importance for people, especially for adolescent. I think Chinese middle and high school should also pay attention to this issue, and find the suitable way to promote the plana and coordinate with different parts. Not only the children, but also the adult should get enough sleep to work. Maybe the company executives should rethink the work schedule. If so, it would be the good news for the office worker.
