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....

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.
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.
