ELI5: For those of us with horrible allergies: How does the body not run out of snot? Eventually, you'd have to dry out, right?

Snot, like most things made by your body, is mostly water. When sick or suffering from hay fever, your body starts consuming extra water to produce mucus and snot. It absolutely is possible to get dehydrated because of this. If you've ever heard someone tell somebody with a cold that they should make sure to drink plenty of fluids, this is partially why.
