In this video, Jill Ali, FNP-C, explains why children run fevers more often than adults — and what that fever is actually telling you.
A Fever Is Usually a Good Sign
It's natural to worry when your child feels warm, but a fever is often a sign that the body is working exactly as it should. Raising its temperature is one of the ways the immune system fights off viruses and bacteria.
A temperature of 100.4°F (38°C) or higher is generally considered a fever.
Why Fevers Are More Common in Kids
Children get fevers more frequently than adults for a few reasons:
- They're exposed to more germs. Daycare, school, and playing closely with other children mean more opportunities to catch common illnesses.
- Every exposure builds immunity. Those frequent minor infections are part of how a child's immune system learns and grows stronger over time.
What Parents Should Watch
Often, how your child is acting matters more than the exact number on the thermometer. A child who is still drinking, playing, and responsive is usually okay to care for at home with rest and fluids.
Contact your provider or seek care promptly if:
- The fever is very high, lasts several days, or keeps returning
- Your child is unusually sleepy, hard to wake, or won't drink
- You notice trouble breathing, a stiff neck, a new rash, or signs of dehydration
