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.
A fever is a high temperature when the body's temperature rises above 37.5C (99.5F). The normal body temperature is between 36C-37C (96.8F-98.6F). The high temperature or fever often lasts around two to three days. Check for high temperature or fever using an appropriate thermometer and following the instructions.
