Causes. Fever occurs when an area in your brain called the hypothalamus (hi-poe-THAL-uh-muhs) â also known as your body's thermostat â shifts the set point of your normal body temperature upward.
But depending on your age, physical condition, and the underlying cause of your fever, you may or may not require medical treatment for the fever alone. Many experts believe that fever is a natural bodily defense against infection. There are also many non-infectious causes of fever. Fever is generally not considered dangerous, but hyperthermia can cause dangerous rises in body temperature. This can be due to an extreme temperature associated with heat injury such as heat stroke, side effects of certain medications or illicit drugs, and stroke.
