What Is a Fever and Why Does It Happen?
A fever is a temporary increase in body temperature, typically signaling that the body is fighting an infection. In children, a fever is generally defined as a temperature of 100.4°F (38°C) or higher. Fevers can be caused by viral or bacterial infections, such as colds, flu, ear infections, or strep throat. While it’s natural for parents to worry, a fever is often a sign that your child’s immune system is actively working to combat an illness.
How to Measure a Fever in Children
Accurate temperature readings are essential when dealing with a fever. Use a digital thermometer for the most reliable results. The method you use to measure the temperature may depend on your child’s age:
- Rectal Temperature: Recommended for infants under three years old.
- Oral Temperature: Suitable for children over four years old.
- Ear or Temporal Thermometers: Convenient for older children but may be less accurate.
Always clean the thermometer before and after use to ensure hygiene and accuracy.
When to Be Concerned About a Fever
Most fevers are not dangerous, but there are times when you should seek medical attention:
- For Infants Under 3 Months: Any fever over 100.4°F should be evaluated immediately.
- Persistent High Fever: A fever above 104°F or one that lasts more than three days.
- Other Symptoms: If your child has trouble breathing, is lethargic, develops a rash, or shows signs of dehydration (such as dry mouth or reduced urination), consult a healthcare provider.
Trust your instincts as a parent—if something feels off, don’t hesitate to seek help.
How to Comfort Your Child at Home
To help your child feel more comfortable while they have a fever, consider these tips:
- Keep Them Hydrated: Offer water, clear broths, or oral rehydration solutions to prevent dehydration.
- Dress Lightly: Avoid heavy blankets or layers, as these can trap heat.
- Use Fever-Reducing Medications: Over-the-counter options like acetaminophen or ibuprofen can lower a fever and relieve discomfort. Always follow the dosage instructions based on your child’s weight and age.
- Rest: Encourage plenty of sleep and quiet time to help their body recover.
Avoid giving aspirin to children, as it can lead to a rare but serious condition called Reye’s syndrome.
Understanding Fevers: When Not to Worry
Not all fevers require treatment or medication. In fact, mild fevers (under 102°F) can play a helpful role in fighting infections. Unless your child seems very uncomfortable or has additional concerning symptoms, allowing a fever to run its course may actually support the immune response.
Preventing Fevers and Common Infections
While not all fevers can be prevented, you can reduce your child’s risk of illness by:
- Encouraging frequent handwashing with soap and water.
- Keeping them up-to-date on vaccinations.
- Teaching them to avoid touching their face, especially their nose and mouth.
- Disinfecting shared surfaces and toys regularly.
A healthy lifestyle, including a balanced diet and plenty of rest, also strengthens the immune system.
