What is Fever in Children?

Fever in children is a condition when a child’s body temperature exceeds normal limits —  usually 37° C. The hypothalamus will send signals to the child’s body to maintain the body temperature at that level. 

Sometimes, the hypothalamus raises the body temperature in response to infection, disease, or other causes. According to KidsHealth, researchers believe that increased body temperature is a child’s body’s way of fighting germs that cause infection.

Most people have a body temperature that changes throughout the day. It is usually a little lower in the morning and a little higher in the evening. This can vary depending on activity, such as when children are playing, running, or playing sports.

Children can get a fever from time to time and it is usually harmless. Often, a fever is a sign that a child’s body is fighting an infection. But when the child wakes up in the middle of the night with a red, hot, and sweaty face, you should consult a pediatrician to get the appropriate treatment.

Causes of Fever in Children

When the hypothalamus raises the body temperature, your child may feel cold and shiver to generate more heat. This is what causes body temperature to rise up. Fever can be caused by several factors, such as: 

  • Infections

In general, fever is usually caused by infection or other disease. Fever helps your child’s body fight infection by stimulating natural defenses.

  • Immunization

Infants and children sometimes develop a low fever after being vaccinated. 

  • Layers of clothing

Infants, especially newborns, can be exposed to a fever under a hot environment. This is because they have not been able to regulate their own body temperature. Fever in newborns can indicate a serious infection. Therefore, infants who have a fever due to wearing layers of clothes should be examined for further diagnosis.

In addition, fever in children can also be caused by:

  • Malignant tumor.
  • Heat exhaustion.
  • Viral or bacterial infection.
  • Inflammation, such as rheumatoid arthritis or joint inflammation.
  • Medications, such as antibiotics and medications for high blood pressure or seizures.
