The issue with this is a lot of schools then let out at 2-230 to account for the earlier start. Most statistics show kids get into more trouble during the 2-3 hours until the parents get home from work than they do at other times.
Seems like 830-330 or 4 would be better.
To be fair the scientists are giving you the conclusion and you never see the data in a news article like this. Has that ever dawned on you or no?
Thats why correlation food studies say XYZ is bad for you one day and good for you the next. Eggs are bad for you. Eggs are also correlated with eating bacon, whod'a thought the average person who eats more eggs also eats more bacon. Eggs are also correlated with higher red meat consumption and smoking. Of course if you eat eggs and do none of those other things the study is useless.
They're basically taking a SWAG (Scientific wild ass guess) beyond anything other than "Evidence of short sleep duration, daytime sleepiness and excessive caffeine use indicate adolescents are sleeping fewer hours than needed." Cited in the actual abstract. That CNN article is one giant SWAG. You think citing a CNN article is acceptable as a footnote in a real scientific study? Its just a media angle. Such hook line and sinker. The video, is also pure SWAG. I know a lawyer who doesn't know what an electron is. Its like having a lawyer read you a science article. You can trust me, I went to graduate school I'm a lawyer! That CNN article is like nails on a chalkboard as far as science goes. It probably spreads more misinformation under the guise of science than if you had just looked at the actual freaking study.

here is the what the CNN article referenced:

As if kids need to be coddled anymore....heaven forbid their parents make them go to bed earlier....
OMG social media is making our kids stay up later so we need to push the school start times past 8:30AM so they get enough sleep...
I can see it now...Sorry boss...I can't come in at 8 anymore because it is bad for my kids to get up early....
For one of my courses, I teach a section 1st period, and one after lunch. I'd have to go back at least 10 years to find a time when the afternoon class did better than the morning class. And, it seems reasonable to assume that my instruction was even better for the afternoon class than it was for the morning class, as I've had one more "practice" of teaching that content. Give me the tired kids - I'll keep them awake, and they're not distracting each other. At 8:20am, they're too tired to get on social media during class.
The scientists are giving you the data, you can decide what to do with it, don't be all mad that they gave you data. Data doesn't coddle anyone or make anyone late for work.
It would seem to me that there are many factors that create the optimal class time for a particular student to achieve academic success.
I know that I preferred early start times. I preferred waking at 5:30 am regardless of when I went to sleep. The first 6 hours of my day my mind functioned much faster then the next 6. I never gave it much thought but I think I am genetically predisposed in that direction. Even today I am aware of being more alert before noon than afterward. Diet may have some bearing on this along with when certain foods are consumed.
Yes, High school kids do. They go to school early, and they normally finish very, very late.
The OP has a link which can get you to the entire journal article, references and all. CNN aside, sleep cycle changes in different developmental stages has long been known. It's just a matter of fine tuning our knowledge and understanding of what happens when you push people out of what is physiologically normal. For example we have known that shift work increases the risk of cancer and cardiovascular disease. Now you can add a significant increased incidence of type 2 diabetes. Obesity is a direct result of chronic sleep disturbance and deficit.
Of course our culture hates the science about as much as 6 day creationists do evolution, because it's economically inconvenient. I should not be surprised if our Puritan based clock slavery is the major reason for our lower life expectancy compared to other first world nations along with the corporate obsession with "productivity".
Probably.
Younger kids here will be going earlier and the older ones later.
Not really, I'm Korean so I should know. Most High school kids are at school for around 8-9 hours or so. The ones that want to get ahead (and into the best universities) spend thousands of dollars per month and another 3-4 hours at Hagwon (for-profit private institutes). Others will either work, go to instrument lessons, sports activities, play video games (Starcraft 2 & League Of Legends), etc.
I like the part about the traffic accidents. I think that might be bunk. If you leave for school later, there are fewer cars on the roads also. You have to be trained to look for outliers and bogus results that do not correlate to the time you actually go to school.
People may hate me for this but I always said that there should be places where people can take power naps when they feel like it throughout the day. Personally i would rather nap during my lunch hour than actually eat.
This is an interesting thread though. I get up at 5:30AM everyday, and the best sleep for me starts between 5:30 and 6:30 so regardless of what time I go to bed, I never feel fully rested because i'm waking up before my, I call it, happy dream state.
Like a Spanish Siesta, yeah thats fine. Science and cultural beliefs are such a bad mix though. You shoudln't need a research study to back your every opinion. I like the idea of a Siesta-like break. You'd be better off studying the Spanish or Portugal workday then measuring just how sleep deprived and caffeinated-up everyone has become.
Articles linked in OP missed this tidbit, but it's from the NPR:

This CNN article does, but it's an "opinion" piece:
http://www.cnn.com/2014/08/28/opinion/snider-school-later-start-times/
this has been known for years but all the gray hairs think teenagers are just lazy.
just flipping around the start times for elementary and jr/high school would be a big help.
You are so full of shit it isn't even funny. Just thought you should know.
Shortly before he died, Mr. Mitchell, the telescope man, spoke of his concern that American science was already losing its competitive edge. He cited the discovery of the Higgs boson, a subatomic particle seen as imparting mass to the universe. The finding was made at a particle accelerator in Europe after tight budgets shut down a rival machine near Chicago.
The financial outlook had fallen far and fast. Congress had long reached across party lines to support government research, for its economic and military rewards and because the distribution of billions of dollars plays well come election time. After rising steadily for decades, federal science financing hit a high point in 2009, in the early days of the Obama administration, as Congress, to stimulate the economy amid the global financial crisis, allocated about $40 billion for basic science.
That bipartisan consensus eroded with the Republican takeover of the House of Representatives in the 2010 midterm elections and the budget battles that followed. Spending on basic research has fallen by roughly a quarter, to $30 billion last year, one of the sharpest declines ever.
The cutbacks translate into layoffs: A group of scientific societies recently surveyed 3,700 scientists and technical managers and reported that 55 percent knew of colleagues who had lost jobs or expected to lose them soon.
The official reticence about private science may reflect, in part, a fear that conservatives will try to use it to further a small-government agenda. Indeed, some of the donors themselves worry that too much focus on private giving could diminish public support for federal science.
“It’s always been a major worry,” said Robert W. Conn, president of the Kavli Foundation, which has committed nearly a quarter of a billion dollars to science and is part of the private effort to increase financing for basic research. “Philanthropy is no substitute for government funding. You can’t say that loud enough.”
Representative Lamar Smith would beg to disagree. Mr. Smith, a 14-term Republican from Texas, helped found the House Tea Party Caucus and, after the Tea Party ferment swept the Republicans to power in the House, became chairman of the Committee on Science, Space and Technology.
