ELI5: Whenever crying extremely hard, why does it instantly calm you down when you drink something?

The other day I was crying like I hadn’t in years because of a terrible panic attack, I couldn’t stop, my mother gave me a glass of water and forced my to drink it. While I was drinking I stopped feeling tense, I calmed down pretty fast from the emotions and my breathing immediately stabilised. I was ‘done’ crying. She said she used to do that when I was a child, and that it would work too. 

Why does such a simple thing stop such a heavy emotional response?

Crying involves a lot of wheezing and deep breathes.

This can become involuntary and uncontrollable.

BUT

Youre brain is hardwired to Absolutely Never Ever Not since Not Ever breath while you’re drinking something, to prevent it from going in your lungs and harming you.

So, that hard override in your brain helps interrupt that gasping and wheezing and deep breathing.
