What Causes Fever

Fever is not a disease. Fever is one of the body's most powerful defenses against the invasion of viruses and bacteria. This is why, when you phone your doctor looking for advice he is not as interested in how high the temperature is as in any other symptoms that may be present.

If you turn to aspirin or paracetamol at the first sign of a fever, you will be depriving the body of one of its best defenses. Fever comes about because pyrogens, the fever-producing substances, appear in the blood and affect the temperature control in the brain, calling for more heat. Pyrogens also stimulate white blood cells to destroy viruses and bacteria.

How To Manage Fever

The common cold and flu are the most common sources of elevated body temperatures in a person. Too much greasy, fried or oily food, sugar or spices can also bring on a fever, as can a sudden change in weather from cold to hot. Fevers of up to even 38.5C (102F) are not dangerous.


The danger comes from dehydration caused by accompanying conditions such as:

  • Excessive perspiration

  • Rapid respiration

  • Coughing

  • Runny nose

  • Vomiting

  • Diarrhea

Just make sure that the person gets plenty of fluids, around 1/2 cup every hour, and treat the source of the infection (ear, chest, gastroenteritis and so on) using treatments that stimulate the immune system.
