Title: is the thirst sensation is an example of a negative or positive feedback control system?

When we become dehydrated, we usually feel thirsty. Decide whether the thirst sensation is an example of a negative or positive feedback control system and defend your choice. (Either answer can be correct, if correctly defended)

why do you bother asking questions you already know the answer to? it takes all the satisfaction out of my answering the question.

negative comes to my mind first and is logical. The only positive feedback I know is labor contractions.

Negative-you feel thirsty so you drink water and then you aren't thirsty. Drinking water doesn't make you feel more thirsty. As said in a different answer, labor contractions are positive-they make the contractions harder and more frequent-thirst make you act in a way to counter this.
