Colleges are starting to wake up to how sleep deprivation（剥夺） cuts into the academic and athletic performance of their students. All-nighters have become a habit in higher education, but a handful of small new studies help document the consequences.

A study at St. Lawrence University in Canton, N.Y., showed what may seem obvious to most of the all-nighters was not an effective way to succeed in school.

“You can’t do your best work when you’re sleep-deprived,” says psychology professor Pamela Thacher, who wrote the study. Thacher studied the sleeping patterns and grades of 111 students to see the relationship between sleep and their GPAs.

Two-thirds of the students reported that they had pulled at least one all-nighter during a semester. Many students believe that it’s a “rite of passage”（标志） to stay up all night during college and that “it’s kind of fun,” Thacher says.

But “if you use all-nighters, your GPA is slightly lower on average,” Thacher says.

Short-term side effects of sleep deprivation include delayed reactions and tendencies to make mistakes.

A Stanford University study may help persuade at least student athletes to make more time for bed. Cheri Mah, a graduate researcher at Stanford, worked with six basketball players, who all ran faster and made more shots over a period in which they slept at least 10 hours a night.

“Athletes who get an extra amount of sleep are more likely to improve their performance in a game,” says Mah, who released results from an ongoing study in June. “It’s not common knowledge, because if people understood how much of a difference getting more sleep could make athletically, they’d apply it more to their lives and not focus solely on nutrition and exercise. ”
