Statistically Speaking

With only one week left until spring break, many Carnegie Mellon students are pulling all-nighters to cram for exams and complete projects. When spring break rolls around, students will have a chance to catch up on some sleep. Until then, here are a few facts about sleep and sleep deprivation:

43.7: The percent of adults, aged 18 to 24, who reported having fallen asleep unintentionally at least once in the last month

33: The percent of U.S. adults who get fewer than seven hours of sleep per night

11 days: The longest recorded time a person has gone without sleep

15 minutes: The difference between the lengths of an average high school student’s sleep before and after Daylight Savings Time
