A fever is your body's natural response to fight off viruses and bacteria by weakening the germs and limiting their ability to reproduce.It also helps burn away toxins and stimulates the immune system. Since a fever is the body’s preferred method for healing itself, it should only be “cured” when the body becomes too weak to handle the infection, when the fever is too high for the body to handle, or when it makes you extremely uncomfortable. While you can handle most fevers at home, you should call 911 immediately if you also have severe dehydration with blue lips, tongue, or nails; severe headache; hallucinations or difficulty walking; difficulty breathing; or seizures.
Drink lots of water. Aim to drink at least eight ounces of water every two hours. Your body can quickly lose moisture and get dehydrated by sweating or sneezing caused by illnesses, such as colds and flu, that are often associated with a fever. Dehydration can cause your temperature to rise and often leads to headaches, dizziness, muscle cramps, low blood pressure, and seizures.
2 liters of water is the daily recommendation for the average adult. Caffeinated beverages in moderation are generally fine, but make sure they are not your only source of fluids. Get most of your daily fluids from pure water.
Sports drinks are acceptable liquids for re-hydration, but use carefully. While these drinks do provide electrolytes, it is usually far more concentrated than necessary. Try diluting one part water to one part sports drink, or one glass of water for every glass of sports drink.
Rehydration solution. You do not need any commercial drinks to help re-hydrate--make your own.
For young children, consider a commercial electrolyte rehydration solution, such as Pedialyte, for young children, since these proportions have been specifically designed for children's bodies.
To rehydrate children, offer at least 1 ounce per hour for infants, 2 ounces per hour for toddlers, and 3 ounces per hour for older children.
