(NEWSER) – OK, you probably won't become a werewolf, but there is evidence that the full moon really does take a toll on people—even if they don't know it's out there. Scientists reviewed data in which subjects slept in a darkened room where they couldn't see the moon. During round moons, the 33 volunteers, who didn't know the study's goal, took an extra five minutes to fall asleep and slept a total of 20 minutes less than they did during the new moon phase. They ranged in age from 20 to 31 and 57 to 74, the Los Angeles Times notes.
