The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors.
This center is located just above the brain stem and secretes hormones that help regulate body temperature. It is this part of your body that orchestrates the many functions that help to control body temperature. All of the autonomic responses of our bodies are controlled by the hypothalamus. It processes the sensory input that the body receives and passes it to the correct area of the brain and body for action. It is this part of your brain that allows you to feel both hot and cold.
