You’ve heard crazy things about full moons; that they send werewolves on the prowl and induce labor in pregnant women. There’s no truth to those myths, of course, but that doesn’t mean the full moon is powerless. The proof: According to a study published in the July 2013 issue of Current Biology, we don’t sleep as well during full-moon phases. It takes us five minutes longer than average to fall asleep when there’s a full moon—and once we’re snoozing, our sleep is 30 percent less deep and 20 minutes shorter.
Why does this happen? No one knows for sure, though it’s been posited that the extra light decreases our melatonin levels, which makes deep slumber more difficult. In other words, that full moon out your window is a lot like that blinking light on your laptop and the neon clock on your cable box.
