Homeostatic feeling is a class of feelings (e.g. thirst, fatigue, pain, desire, malaise, well-being) that inform us about our physiological condition. [1] In his earlier work Antonio Damasio used " primordial feeling " but he now prefers the term "homeostatic feeling" for the class.
The hypothalamus simultaneously stimulates the nearby thirst center causing an almost irresistible (if the hypertonicity is severe enough) urge to drink water. The cessation of urine flow prevents the hypovolemia and hypertonicity from getting worse; the drinking of water corrects the defect. Hypo-osmolality results in very low plasma ADH levels.

[1] It arises from a lack of fluids or an increase in the concentration of certain osmolites, such as sodium.
