Negative. When thirst increases, it stimulates you to drink and so thirst then decreases. Thirst decreases itself in this way and so it is a negative feedback system. An example of positive feedback is addiction: you smoke a cigarette, which makes you want to smoke more and so smoking increases itself, whereas thirst does not increase forever because it makes you want to drink something.

Thirst is a negative feedback in humans with Diabetes and some other diseases, means the body cannot regulate it's insulin. Thirst is a positive thing when a person is dehydrated, signaling a desperate need to replenish the body fluids so the blood can circulate and the kidneys can be cleansed.

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.

1.positive feedback is like acceleration..if there is an increase the reaction will be an increase like an increase in a certain hormone in ur body increases reabsorption of a certain material
2.negative feedback is opposition a certain increase in the thyroxine levels in the blood will lead to a decrease in th thyroide activity while a decrease in the levels will trigger the tsh so thyroid produce more of the hormone....
so u gotta find out what makes u feel thirsty?? and then concider it and i'll look it up in my physiology book......just to b a ccurate

Both, it is positive because it replenishes what is lost in a normaly functioning body, it is negative if some function in the body is abnormal such as one sign of a form of diabetes is excessive thirst.
