Night owls not so wise after all

Students who think of themselves as 'night owls' - feeling more alert and doing their better work at night - could end up with worse grades than their early-bird counterparts. Researchers from Hendrix College in Arkansas studied 123 students and found that night owls had poorer sleep hygiene than other students. Sleep hygiene is defined as a set of good practices helpful for getting a decent night's sleep such as a regular bedtime routine, going to bed and waking up at the same time and sleeping in a comfortable bed. The night owls had lower grades than other students and slept, on average, 41 minutes less each night.
