A rake???

From Science Daily

February 1, 2006 — Teenagers’ morning drowsiness is often caused by out-of-tune body clocks, in a condition known as “delayed sleep phase syndrome.” Scientists now say that timing exposure to blue light — avoiding it during the first two hours of being wake, then getting a good dose of it — can help restore the sleep cycle, so teens feel sleepy earlier at night and are more awake in the morning.

I’d actually like to try getting some blue LEDs as the article later recommends. Might be a fairly simple solution to the problem of tired teens in the classroom. Of course, that assumes that they’ll actually go to bed on time.
