Much like a thermostat regulates the temperature inside your home, the hypothalamus regulates your body temperature, responding to internal and external stimuli and making adjustments to keep the body within one or two degrees of 98. Measures may be required to warm a hypothermic patient or cool a febrile patient to prevent cardiorespiratory instability. When your body is exposed to extremely low temperatures for several hours, it loses heat faster than it can produce it, so your body temperature may drop to dangerous levels.

Most often, increased body temperature is regarded as a symptom of the common cold and is being fight with antipyretics. This concept is so important that control of thermoregulation is often the principal example cited when teaching physiological homeostasis. Homeotherms have the ability to maintain a relatively narrow core temperature range despite changes. However, the subject matter is rarely presented as a composite whole.
