Why does the baby's fever go down but their hands and feet are cold?

Patient's question:

The baby had a high fever today, so I gave them fever-reducing medicine. The fever is gone, but why are their hands and feet cold? Besides, for an 18-month-old baby, using fever-reducing medicine is better than using infant fever-reducing suppositories because it has fewer side effects.

Doctor's answer:

The baby has a fever with a temperature below 38.5 degrees Celsius and needs medication to reduce body heat. Suppositories and fever-reducing drugs can be used to achieve a cooling effect. As long as the dosage and usage instructions are followed, there will be no side effects.
After the baby's fever subsides, if the limbs feel cool, it indicates poor blood circulation. During the fever reduction process, it's important to prevent chills. The best method is to use medication while also appropriately increasing fluid intake, such as drinking some plain water to replenish body fluids. Combining this with a lukewarm bath can enhance the effectiveness of the treatment.
