Why do horses mouths foam?

Why do horses mouths foam?

Movement mainly coupled with sweat or saliva.

When a horse is relaxed, or chewing, or rubbing their lips together (or sometime choking) the saliva creates little bubbles and seems like a white foam. Just like if you were to spit on something, most times it is a whiteish foam like spit.
