If think people put way too much importance into clock time. It doesn't really matter what number the clock shows when you wake up. The problem is to sleep early enough to be able to wake up. If you sleep too late you will have a hard time waking up, whether you are trying to wake up at 6am or at 11am. Unless you are particularly sensitive to sunlight, in which case you will wake up with the sun... so certainly quite a bit earlier than most teens would like to. Maybe I'm completely wrong, but it certainly wouldn't have helped me. At my very worst (around 19 or 20) I had a hard time waking up to attend classes at 1:30pm... Which makes sense given that I was going to sleep at 5~6am (CS, Warcraft III, etc.) and I'm a big sleeper (still need a solid 8 to 8:30 hours per night at 35).

Clock time doesn't matter, you're right, but it very does matter what time school starts in relation to when the Sun goes up and down - at least if teens spend a good amount of time outside or in rooms with windows.

  Most of school year it is dark long before they go to sleep regardless of when they go to sleep. Half the time it is dark when they are leaving activities and it is going to be worst if they stop DST. How much difference makes 4 hours of dark before sleeping vs 5 hours of dark? It also changes constantly. Over year there is hours of difference for when sun goes away, with sun being available longest in summer.

    Right? Sunrise today was 7:21 AM, sunset is 5:38 PM. So in Indiana in the winter school should be from what? 9 AM to 3 PM so kids have time to have an early dinner, do their homework and hit the rack by 6 PM? Then what about on June 1st? Sunrise is at 6:20 AM and sunset is at 9:07 PM.

    It isn't a matter of time since you were exposed to sunlight that causes sleepiness. Rather, you body has its own 24 our cycle called the Circadian rhythm that is phase locked to the solar cycle. If you go into a cave far away from the sun you'll still have a roughly 24 hour sleep/wake cycle but over time it will drift away from the actual day cycle. As far as I'm aware the duty cycle of 24 our sunlight input doesn't have any effect on the ability of the Circadian rhythm to phase match with it. If you're interested in learning more I'd recommend the book Why We Sleep by Matthew Walker.

      So basically, regularly going to sleep sooner and waking up sooner is impossible, because sun light dock it. But actually, it has nothing to do with sun light and is regular cycle that is magically tied to clock number? And it also all works the same regardless of where within time zone you are located despite there being over an hour difference between sun times. Plus irony: And it is also completely different for adult programmers who totally need to work evenings (never ever mornings) and night to be crunch effective unlike administration adults who are morning people.

        I was only talking about one process above. There are others too, like sleep debt. Night shift workers can train themselves to sleep in the day and remain awake through the night but at a pretty steep psychological and physiological toll. Scientists have been studying the whole area pretty intensely for the last half-century or so leading to wonderful things like malatonin pills. If you want to know more but don't want to read a whole book there's always Wikipedia. https://en.wikipedia.org/wiki/Sleep https://en.wikipedia.org/wiki/Sleep

        Reverse this. I had no alarm for 5 years and did what my body said: when I was asleep I would sleep. When I felt like waking up I would. My body immediately shifted to what I already knew: going to bed at 5-6 am, waking up at 1-2pm (I roughly sleep 8.5 hours, sometimes 9). Never felt more rested. I now wake up at 10 am. It's ok, but I always feel SO rested when I sleep until I needed. Just having an alarm SET puts me on a bad path, even if I have 10 hours.
