Question

why do we feel thirst

Answer 1

Answer:

we feel thirsty when we didn't drink water for so long......

Answer 2

It arises from a lack of fluids or an increase in the concentration of certain osmolites, such as sodium. If the water volume of the body falls below a certain threshold or the osmolite concentration becomes too high, structures in the brain detect changes in blood constituents and signal thirst.
