Well, now science has spoken on why staying up late is not the best strategy:
… a new study published in the journal Child Development finds that
when teens don’t get the sleep they need on a given night, the next
day all kinds of things can go poorly.
"What we learned is that when kids cram, particularly at the expense
of sleep, the next day they're more likely to have academic problems
even though they spent more time studying that night," explains
researcher Andrew Fuligni of UCLA.
"These findings may come as a surprise to many researchers, educators,
parents and teens who assume that more studying will surely lead to
better grades," says Amy Wolfson, a professor of psychology at
the College of the Holy Cross in Worcester, Mass.
The study builds on a body of evidence that finds sleep and learning
are inextricably linked.
"Lots of things happen during sleep," explains Helene Emsellem,
director of The Center for Sleep and Wake Disorders in Chevy Chase,
Md. "We don't just physically restore ourselves." We also
process all the information we've gathered during the day. "We
take the information and organize it and make all the connections,"
Emsellem explains. Without adequate sleep, students don't learn as well.
