The need to drink is our only response mechanism to being dehydrated. This occurs when the blood becomes too concentrated. Stimulates the thirst mechanism

Essentially there is a thirst center in the brain (hypothalamus). There are feedback loops that provide water retention involving the kidneys (Reninā€Angiotensinā€Aldosterone System) and also drive the thirst mechanism in the brain.
