Study finds students who pull all-nighters have lower GPAs than students who opt for sleep. All-Night Study Sessions Bad for Grades

ALBANY, N.Y. (AP) - Staying up late to study probably isn't a
good idea after all.
A new study indicates that students who opt for sleep rather
than late-night studying get better grades than classmates who pull
all-nighters.
A survey of 120 students at St. Lawrence University in northern
New York found that students who never pulled an all-nighter have
average GPAs of 3.2. In comparison, those who have stayed up late
to study have average GPAs of 2.95.
One researcher who did another study that yielded similar
results says the brain just doesn't function as well late into the
night.
Another sleep expert says the findings make sense, citing data
showing that a lack of sleep interferes with concentration and
performance when it comes to objective testing.
Of course, there are those students who still do well despite
being night owls. Researchers say that could be due an individual's
own body clock.
