If you want to hit the snooze button when the alarm goes off, you’re in good company—despite claims that it does not help the brain’s ability to wake up. Researchers in Sweden investigated snoozing and its effect on sleep, mood and brain function. In both questionnaires and sleep laboratory conditions, those who hit the snooze button for thirty extra minutes slightly performed better on cognitive tests upon waking compared to those who had to wake up from a deep sleep. The study, published in the Journal of Sleep Research, concludes snoozing for thirty minutes does not have negative effects on sleep. Authors note this study only included people who find it easy to go back to sleep after each alarm. For that reason, snoozing is most likely not for everyone.
