How is it that your nose can produce an almost endless amount of snot when you are sick, even after you blow your nose dry?

We’ve got pretty big sinus cavities inside our cheeks and foreheads. It can seem like your blowing your nose *forever* when you’re sick, but we underestimate the amount of snot our noggins can store. Plus, if you’re fighting an infection, your body’s gonna keep producing more mucous to try and flush it out.

Aside from the other part of the answer already given, that your sinus cavities are actually pretty big, we also overestimate how much snot is coming out every time, and often confuse inflammation for snot. So your sinuses are inflamed and puffy, only allowing a certain amount of snot to come out in every blow.

Try to blow your nose very very gently, one nostril at a time. And don’t inhale the powder that flies off most tissue paper.
