Daily body temperature in children: What is normal?

The "normal" body temperature in children is usually between 36.5 and 37.5 °C.

However, these values ​​may vary slightly depending on the measurement method:

• Rectal (in the buttocks): 36.6 to 38.0 °C
• Oral (in the mouth): 35.5 to 37.5 °C
• Axillary (under the armpit): 36.5 to 37.5 °C
• In the ear: 35.8 to 38.0 °C
• with MARY by sticklett (on the chest): 35.8 to 38.0 °C

Especially in childhood, body temperature can fluctuate somewhat more than in adults, which shows an adaptation of the child's metabolism to the environment.

Therefore, it's important not only to look at individual readings (which can often be confusing) but also at the temperature trend over a longer period, for example, overnight. With MARY by sticklett, the smart ladybug, this is very easy. Find out how here.

The daily temperature cycle

Body temperature follows a 24-hour rhythm, which is controlled by the circadian rhythm. Temperature is usually lowest in the morning and rises throughout the day. The highest temperature is often reached in the late afternoon or early evening. These fluctuations are completely normal and no cause for concern. However, this natural increase can easily be mistaken for a fever if it is not interpreted correctly.

CAUSES OF TEMPERATURE FLUCTUATIONS 

In addition to the natural daily rhythm, the body temperature of children can also be influenced by physical activity, stress or emotional factors and can fluctuate above and below the normal range of 36.5 and 37.5 °C.

Body temperature fluctuates above 37.5°C

A rise in body temperature can often indicate heatstroke, caused by wearing too many clothes or spending extended periods in very warm rooms. Often, covering the child or removing a layer of clothing helps to lower their temperature. Temperature can also rise slightly after eating or a warm bath. Such temporary increases usually return to normal after a short time.

Parents should be vigilant if the temperature rises above 38.0 °C or if other symptoms such as malaise, weakness, or loss of appetite occur. In such cases, it is advisable to consult a doctor, especially in the case of infants and young children.

Body temperature fluctuates below 36.5°C

A body temperature of 35.2 °C in a child is usually not a cause for immediate concern, but it can indicate mild hypothermia. It's quite possible the child is simply cold, which is often caused by factors such as a cold environment, insufficient clothing, or prolonged exposure to cold rooms.

However, if the temperature remains below 36°C for an extended period, or if the child exhibits symptoms such as shivering, paleness, fatigue, or general malaise, the temperature should be monitored. In such cases, it may be advisable to dress the child more warmly or move them to a warmer room and take their temperature again after approximately 30 minutes.

If the low temperature persists or the child shows additional signs of discomfort, it is advisable to consult a doctor to rule out possible causes such as infection or other health factors.

HOW PARENTS CAN LEARN TO UNDERSTAND THEIR CHILD'S BIORHYTHM:

With MARY by sticklett, parents can better understand their children's biorhythms. Regular, straightforward measurement and tracking of vital data makes it possible to recognize connections between body temperature, environmental influences, and the child's behavior. This makes it easy to determine what is normal and when action is actually needed.

This understanding often allows parents to be reassured and avoid unnecessary, stressful doctor visits, as they can keep their child's natural rhythm in mind.
