Question

Why do people who otherwise breathe normally during the day snore at night?

In: Biology

Answer 1

Because when a person lays down gravity pulls the tongue, tonsils, and uvula in a different direction than when upright. Also, when sleeping, muscles relax and the tongue and tonsils can cover the back of the throat and cause the snoring.
