Babies generally sweat after using antipyretics for fever, and the sweat takes away the heat from the body surface thereby cooling the body. Therefore, when sweating during fever does not show a drop in body temperature, you can wait for a while for the sweat to evaporate before monitoring the body temperature. It is important to pay attention to moderate hydration, because the baby’s unobtrusive water loss increases when the fever persists, and because he or she sweats a lot after using antipyretic drugs and is prone to dehydration. If the body temperature is not particularly high, you can also use physical cooling methods, head resting on an ice pack, or using warm water to wipe the neck, armpits, groin and other places rich in the distribution of large blood vessels. If the fever persists and the baby’s mental state is depressed, go to the hospital promptly.
