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.
Normal temperature regulation without illness. Deep inside the brain (in the âhypothalamusâ) is a temperature center, sort of like the thermostat in your house. Its job is to try to keep the blood at a constant temperature (typically 98.6, although this can vary by a degree or so in either direction).
