Why do people snore?

Updated February 21, 2017 | Factmonster Staff

Everybody snores. The snoring noise we make while sleeping comes from the vibration of our nasal passages as we breathe. The muscles in your nose and throat relax when you sleep and narrow your airways enough to make it easy to snore. Only some people have medical reasons for their snoring. The rest of us naturally make those embarrassing noises in our sleep.
