Question:
My child fell asleep about 30 minutes ago, and I just checked their temperature. It is currently 37.4°C. Is this considered a mild fever?
Answer:
It is completely understandable to be concerned about your sleeping child's temperature.
Current Situation
A temperature of 37.4°C is within the normal range. When a child falls asleep, their body temperature naturally rises by 0.3 to 0.5°C. The reading can also be easily influenced by blankets, clothing, and the room temperature.
What You Can Do Now
• Remove one layer of their blanket and maintain a comfortable room temperature between 22 and 24°C.
• Ensure your child is dressed lightly in just a single layer of clothing.
• Check the temperature again in 10 to 20 minutes. If it settles at 37.5°C or below, it is completely normal.
When to Take Further Action
• If the temperature is 38.0°C or higher after they wake up, make sure they drink plenty of fluids and continue to observe their symptoms throughout the day.
• Seek medical attention from a doctor on the same day if your child is breathing rapidly, appears excessively lethargic or limp, or has not urinated for more than 8 hours.
If your child is sleeping comfortably, it is perfectly fine to simply continue monitoring them for now.
