ELI5 why drinking water is bad after you eat very spicy foods.

I have never understood why it makes the spiciness way worse.  Please help!

The thing that makes the heat and spice is Capsaicin. It does not dissolve in water. Drinking water just spreads it around in your mouth.

The hot stuff does not like water. So when you drink water the hot stuff covers more of your tongue. If you want to get rid of the hot stuff, drink milk. The hot stuff likes milk and you can get it away from your tongue.
