What is a fever?
Fever is an abnormal rise in body temperature is most often caused by a viral or bacterial infection. Normal body temperature varies from 36.7 to 37.2 C. One should not be unduly concerned, unless body temperature rises above 38 C in adults or 38.1 C in children.
Running a high temperature is a defence mechanism by the body to destroy harmful microbes. When destructive microbes or tumour cells invade the body, the immune cells rush to fight them, releasing proteins that tell the hypothalamus to raise body temperature.
Fever is often associated with symptoms such as flushed face, chills, a feeling of weakness and light-headedness, aching muscles and joints, loss of appetite and increased pulse rate.
When can running a fever cause problems?
There are instances, however, in which a fever can cause problems. A moderately high fever may pose a risk for people with cardiac problems, since it makes the heart beat faster and work harder, and can cause irregular heart rhythms, chest pain or heart attack.
Very high fever during the first trimester of pregnancy can cause birth defects.
Fever over 41 C, especially for prolonged periods, can cause dehydration and brain injury.
What symptoms are associated with fever?
Fever is often associated with symptoms such as flushed face, chills, a feeling of weakness and light-headedness, aching muscles and joints, loss of appetite and increased pulse rate. Perspiration is the natural result of the body's attempt to lower its temperature.
Fever with a sore throat may indicate influenza, tonsillitis, pharyngitis, mumps, meningitis or glandular fever.
Nutritional requirements during a fever?
Diet should be kept light but nutritious until the fever drops. Since a fever will deplete the body's energy stores, caloric needs are increased and intake should be adjusted accordingly.
Appetite is typically reduced, so a fortified, high-protein meal replacement shake may be an appropriate way to maintain caloric needs and prevent muscle wasting.
A high fluid intake is essential to compensate for the loss that occurs with the fever. Lemon and honey drinks are good.

Some interesting points on Fevers...
- Get plenty of rest while the temperature is elevated. Avoid rapid changes in temperature. Consume large quantities of liquids to prevent dehydration and flush out toxins.
- Drink distilled water and juices but avoid solid food until fever breaks. The digestion of food uses up a lot of energy better spent on getting well. Vegetable broths and soups are acceptable if the person is hungry.
- As long as a fever does not get too high (above 39 C) let it run its course. It helps to fight infections and eliminate toxins. Seek advice.
- If the body temperature rises above 37.8 C (39.5 C in a child), take measures to reduce the fever, and consult a health care provider. This can be a sign of a worsening infection.
- Take sponge baths. Use water that is 1 degree lower than the person's temperature. If the water is too cool it will cause problems.
- In all cases of fever in children, seek advice from your health care professional immediately.
