The answer is Hypothalamus.
The hypothalamus is a structure deep in your brain. It is the main connecting link between the endocrine system and the nervous system of body.
Why do humans feel thirsty?
- The primary "thirst centre" in the brain is the hypothalamus, a deep structure that also regulates body temperature, sleep, and appetite.
- Special sensors in the hypothalamus constantly monitor the concentration of sodium and other substances in the blood.
- The hypothalamus also receives input from sensors in the blood vessels that monitor blood volume and pressure.
- When blood volume or pressure drops too low—for example, because of bleeding or excessive fluid loss through sweat or diarrhea, or when blood sodium levels rise too high because of salty snacks or certain illnesses, the hypothalamus sends a strong message: Drink something.
