A flu fever occurs when your body temperature increases. Flu fevers may last from one day to as long as a week. They may get as high as 106ºF. You should consult your doctor if your fever exceeds 103ºF.
Feed a Fever
The saying goes, "feed a cold and starve a fever." We can put this to rest. Starving your body from necessary nutrients may prolong your flu symptoms. Fluids and foods are necessary fuel for your body's immune system. So while you may not be merry, at least eat and drink.
Avoid the Flu, Avoid the Fever
There's nothing you can do to avoid a fever when you have the flu. It's best to try to avoid the flu altogether. Keeping your hands clean can help reduce exposure to infections such as the flu. Also, avoid touching your eyes, nose and mouth. Remember, anyone who is exposed to the flu can get it; so keep the flu at bay as best you can.
