What should be done when a four-year-old boy develops a fever in the middle of the night?

A four-year-old boy suddenly developed a fever of 39°C at night, accompanied by coughing and a runny nose. This may be an acute upper respiratory tract infection caused by a viral or bacterial infection. When such a situation occurs at night, parents should remain calm and not become overly anxious, but should take some measures to help relieve the child's discomfort and monitor the progression of the illness.

1. Physical cooling: Try applying a wet towel to the child's forehead or wiping the body with lukewarm water to help reduce body temperature. Avoid using alcohol for擦拭 (wiping), as it may irritate the skin.

2. Encourage fluid intake: Promote frequent water consumption to help replenish fluids lost in the body and support metabolic processes.

3. Safe medication use: If there are children's fever-reducing medications available at home, such as ibuprofen or acetaminophen, an appropriate dose may be administered according to the drug instructions and the child's weight. However, it is best to consult a doctor before using any medication for the first time.

4. Monitor body temperature: Measure the child's temperature at regular intervals. If the fever remains persistently high, it is recommended to seek medical attention promptly.

5. Medical advice: If the child exhibits additional symptoms such as severe coughing, vomiting, diarrhea, or appears listless or unwell, immediate medical treatment at a hospital is advised.

While waiting for daytime to arrive, remain calm and closely monitor the child's condition. Contact emergency medical services if necessary. Ensure the child gets adequate rest, wears loose and comfortable clothing, and keep the indoor air well-ventilated to create a quiet and comfortable environment for recovery.
