What is a Hypothalamus and What Does It Do?
The Hypothalamus is a part of the brain and provides the primary link between the endocrine system (hormone production) and the nervous system (the body’s command center). The hypothalamus receives information about the state of your body, then reacts and responds to that information in an attempt to maintain homeostasis. In other words, the hypothalamus is tasked with the important function of providing balance for your mind and physical body.
The hypothalamus is like a “smart” control center in your brain. Some of the most basic functions regulated by the hypothalamus include blood pressure, thirst, hunger, sleep, body temperature, mood, and even sex drive. The hypothalamus attempts to achieve balance through the nervous and endocrine systems. It does this either by directly controlling the autonomic nervous system or adjusting the levels of hormones in the body. As you can imagine, this little part of the brain plays a very important role.
