Fevers

A fever means your body temperature is higher than the normal 98.6 degrees Fahrenheit. Fevers are actually a sign that your body is fighting an illness. Most fevers are not dangerous and go away on their own.

Why Your Body Gets a Fever

When germs enter your body, your immune system fights back. One way it fights is by raising your body temperature. The extra heat makes it harder for germs to survive.

You might feel hot, sweaty, or have chills during a fever. Your body is working hard to make you better.

What to Do When You Have a Fever

Rest and drink plenty of fluids. Water, juice, and soup are all good choices. Wear light clothing and do not bundle up in heavy blankets.

A parent can use a thermometer to check your temperature. If your fever is very high or lasts more than a few days, see a doctor.
