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: All-nighters are 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. “Pulling all-nighters gives in your (overall) sleep” and makes it difficult to reach full academic potential.
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.
