Once again, science proves the obvious, and once again, it's ignored.
All these researchers could have saved themselves a whole lot of time by talking to my high school Geometry teacher, who also taught Trig/Intro Anal (that's how the name appeared in the course schedule, snicker snicker) the next year. Same teacher, same hour of the day, but two consecutive years.
For geometry I was wide awake, attentive, and got the best grades in the class. The next year, however, I slept almost every day. Drove Mrs. Margrave crazy. I also fell asleep pretty regularly in physics (right after lunch), but Mr. Jaeger seemed to be much less disturbed by this. I was not an after-school napper either.
I still did pretty well in Trig/Intro Anal, but not as well as I'd done in geometry the previous year. This is entirely sleep-related.
It's always bothered me that so many people blame sleep deficiency on the supposed poor habits of the sleep-deprived person. I'm 30 now. I think if it were possible for me to fall asleep at 10 every night (or even just at a consistent time from night to night) I would have learned to do so by now. I'm not an insomniac by choice.
