Fever

The hallmark of the flu is often the uncomfortable fever that accompanies the disease. A clear sign differentiating the flu from the common cold, the fever is noticeable when one’s body temperature rises above the normal range. Fevers is caused when the temperature set-point increases the due to muscle contraction resulting in a cooling effect throughout the body, in order to counteract the cold the body produces greater heat and efforts to maintain warmth. This then results in the set-point returning to normal levels however the affected person is left feeling hot, flushed and rather uncomfortable.

While treatment of fever is not necessary, anti-inflammatory medication can help the affected person feel more comfortable and rest a little easier.
