Facts about Fever

Fever is actually the body's natural way of defending itself from invaders like viruses and bacteria, because many of them can't survive in the body due to the high temperature caused by a fever.

It is very important to understand that a fever is a normal response of the body to foreign invaders like bacteria and viruses. The body recognizes a foreign invader and the brain acts to increase body temperature to make things unsuitable for the foreign invader. Most bacteria can only tolerate a certain temperature range and once outside of it, do not survive. Fever is not the result of damage to the body by germs the body creates fever in response to exposure to germs. Fever has been shown to increase levels of antiviral substances the body produces.

Fever is an increase in body temperature and is one of the body's normal defenses against attack from an infection or another disease. It is therefore a symptom, not a disease itself. A part of the brain that acts as the body's thermostat controls body temperature by balancing hot and cold signals throughout the body. Factors that influence body

Recommendations for temperature measuring techniques vary according to age. Generally Thermometer is used to measure fever. When someone has a fever, the body raises the normal body temperature (as measured orally) above 37.5°C (99.5°F) to try to kill bacteria or viruses in the body. A rectal temperature above 38°C (100.4°F) or an underarm temperature above 37.3°C (99.1°F) is also considered a fever.
