This does not work with teenagers, in whom bedtimes are practically unenforceable, but whose need to get to school in a timely fashion does a reasonable job of imposing a getting-up time. They are chronically sleep deprived. Smaller children, I imagine, have even less of a chance of managing the feat.
Don’t teenagers have brain-chemistry that makes them have trouble getting to sleep at a reasonable hour? I’m not finding a good reference, but I remember reading that, and that the effect doesn’t apply to children.
Roughly one-quarter of the kids fell into the borderline-acceptable category, meaning they reported eight hours of shuteye nightly. The overwhelming majority fell short — with 30.2 percent reporting seven hours, 22.8 percent slumbering closer to six hours, 10 percent catching a mere five hours of sleep, and 5.9 percent claiming to nod off for no more than four hours most weeknights. Just the thought makes me yawn.
Certainly, schools don’t help the situation by starting classes earlier for teens than they do for younger kids — even though puberty and other developmental changes lead to adolescents needing more sleep than grade schoolers, not less. But there could be other issues. Like what share of teens don’t get enough sleep because they’re naturally night owls (like me) and find almost anything before 2 or 3 a.m. more interesting than slumber?

In an attempt to reset the students’ daily biological clocks Biological clocks, or circadian rhythms, so that they would be more alert in daytime and go to bed earlier, the researchers exposed some students in their classrooms to especially bright light between 8 a.m. and 10 a.m. Other students were exposed to muted red lighting. But the bright light neither changed students’ sleep patterns nor improved their scores on tests of mood, vigor, and cognitive function cognitive function Neurology Any mental process that involves symbolic operations–eg, perception, memory, creation of imagery, and thinking; CFs encompasses awareness and capacity for judgment .
I remember. It was a very high-profile study that asserted a phase-delay in the teenage sleep cycle. The study was cited for a while in arguments to shift the school day later by a couple hours.
That makes sense—but let me add that the idea that it is a myth that bedtimes must be enforced fits another observation: parents also seem to believe that they have to persuade or force their children to eat; yet in big families where no one can make sure everyone eats, all the children learn quickly to eat on their own.

They do? I would be very surprised at parents who believed this.
Eating satisfies a natural desire and feels good. Sleeping means stopping the fun thing you’re doing and lying down in a dark room; why would kids want to do that?
I have two kids. If left to their own devices, they would eat the tastiest things on their plate, then stop (then complain about being hungry an hour later). They would never eat anything remotely healthy, and subsist entirely on chocolate if given the choice.
Since we have evolved to value fat and sugar as being the tastiest substances, children do have to be taught/persuaded to eat healthy food.
They also do need to be told when to go to bed. The times at which we have tried to let them set their own bed times have resulted in them trying to stay awake as long as they possibly can, until they fall asleep in the middle of whatever they were doing. They almost never voluntarily go to bed, no matter how obviously tired they are.
Eat a meal with a family with a single child. In many cases, the parents will spend much of the meal ordering or pleading with the child to eat their food. Then eat a meal with a family with 6 or more children. That probably won’t happen.
I do know one kid who really won’t eat on his own; if you don’t coax him into eating, he won’t eat enough. But that’s unusual.

...Woah. Thanks to your comment, I just remembered vividly how much my school years sucked.

That’s it. Thanks!
