Have you ever wondered what makes you hungry, thirsty, sleepy, or sweaty? The answer is the hypothalamus. The hypothalamus is a tiny structure located at the base of the brain. It regulates functions such as sleep, thirst, hunger, and countless other functions. For example, if your body doesn't have enough water, the hypothalamus gets hormonal "signals" from your body. It then secretes another hormone into your brain that tells you that you need to get water. This is what makes up the "thirsty" feeling we all get when we don't drink enough fluids.
