The normal body temperature is between 36.5°C and 37.5°C. In healthy kids, fevers usually don't indicate anything serious. While it can be worrying when your child's temperature rises, a fever can actually be a good thing — it's often the body's way of fighting infections. High fever, however, can make a child uncomfortable and worsen problems such as dehydration.
Fevers are extremely common in children, with between 40-60% suffering a raised temperature each year. The body’s normal temperature is around 37 degrees Celsius (°C), however it can vary according to the time of day. If your child’s temperature is over 37.5°C when measured orally or 38°C when taken rectally, then they are considered to have a fever.
A fever can often be a good sign. Generally, fevers happen when your child’s immune system is fighting off infections such as colds, coughs and ear infections. At the first sign of attack, the body’s defences launch infection-fighting chemicals into the blood. These chemicals also affect the body’s thermostat, which is located in the brain and called the hypothalamus.
There are various ways to check for a fever in children:
- Oral. The thermometer is inserted under the tongue, the mouth is closed and a reading is taken.
- Rectal. The thermometer is gently inserted into the rectum (child’s bottom) and a reading is taken.
- Armpit. The thermometer is placed under the armpit and the arm is held against the side of the body while a reading is taken.
- Ear. A digital thermometer is inserted into the ear and a reading is taken.
It is important to remember that the temperature can vary according to the part of the body where it is measured, so always take the temperature at the same site.
If your child has a fever, but is fine in every other way, then you may not need to do anything aside from making sure they are properly hydrated. When a baby or child is breastfed or bottle fed, the most appropriate fluid is breast milk or formula. In addition, cooled pre-boiled water can also be given to keep fluids up.
If they seem unwell or distressed then you can consider giving children’s pain relief, such as Panadol®.
Some other tips include:
- dressing the child in light clothing
- keeping the child cool by ensuring a comfortable room temperature – take care not to make it too cold
