The hypothalamus, which is a portion of the brain, controls the regulation of body temperature. The process that allows the human body to maintain its core temperature is called thermoregulation.
The hypothalamus sends signals to various parts of the body, such as the glands and nervous system, when its core internal temperature begins to fluctuate too high or low. This area of the brain contains the components to control the body’s temperature along with the key temperature sensors. Therefore, when a person gets too hot, the hypothalamus sends a signal to start sweating. It is also what makes people shiver in the winter if they get too cold.
