It is easy to become dehydrated when you have a fever. Watch for early signs of dehydration and drink extra fluids, especially water. Adults should drink at least 10 glasses of liquid a day to replenish lost fluids. Children between the ages of 4 and 10 should drink at least 6 to 10 glasses. You may feel better if you eat light, easily digested foods, such as soup.

Many people find that taking a lukewarm [80F to 90F] shower or bath makes them feel better when they have a fever. Do not try to take a shower if you are dizzy or unsteady on your feet. Increase the water temperature if you start to shiver. Shivering is a sign that your body is trying to raise its temperature. Do not use rubbing alcohol, ice, or cold water to cool your body.

Dress lightly when you have a fever. This will help your body cool down. Wear light pajamas or a light undershirt. Do not wear very warm clothing or use heavy bed covers. Keep room temperature at 70F or lower.

If you are unable to measure your temperature, you need to look for other symptoms of illness every hour while you have a fever and follow home treatment measures.

Be sure to check your temperature every 2 to 4 hours to make sure home treatment is working.
