Why my nose gets runny when I cry (lemmy.blahaj.zone)

Pretty much every time I cry, my nose gets super runny and my throat gets slimy. Why is that?

Crying is when your head releases liquid.

It’s not an eye thing; it’s a head thing.

Your tear duct drains into your nasal cavity.

And so do your ears, via the Eustachian tubes! They drain to your throat, I don't know how close the eye/ear drains are to each other.

There's a visible hole on the inside of your lower eye lid which drains excess tears into the sinuses:

Your sinuses are all connected up in your noggin.
