Jawbone, the maker of a tracker called UP, just released a study of the sleep habits of tens of thousands of students, ages 18-22, on college campuses, reports NPR.
And they found some pretty interesting stuff:
- Students aren’t as sleep-deprived as we might think. The overall average was 7 hours and 3 minutes during the week, and 7 hours 38 minutes on the weekends.
- The tougher the school, the later the students go to bed. There was a strong correlation between rankings in U.S. News & World Report and bedtime. At Columbia, Stanford, MIT, Princeton and Brown, the midnight oil burns past 1 a.m. But these students don’t sleep less over all — they’re just night owls. That trait, in turn, has been linked to general intelligence.
- Women go to bed earlier, on average, and wake up earlier than men, sleeping more overall. On weekends, for example, the women turned in at 1 a.m. and the men at 1:43 a.m. There’s been some research recently showing that, for biological reasons, women actually need more sleep than men.
