ELI5: Why do people snore when they sleep but not when we're awake?

Why aren't we snoring all the time? Are we actively regulating are breathing so we don't when we're awake? How and why?

Snoring is due to the fact that your mouth muscles are not tightened and that you usually have your head tilted back (or at least horizontally with your nose pointing to the celling). Basically, your palate loosen and your to~~u~~ngue roll back a bit thus kind of blocking the airway, but not totally which is why it makes so much noise.

Now, when you are awake, your mouth muscles are more tightened so you are not blocking your own airway.
