What is the best physical cooling method for children with high fever?

Suggestion: Family members can paste antipyretic paste on the child's forehead to cool down, or can place ice packs on the neck, armpit, groin, popliteal fossa and other parts where there are large blood vessels to cool down. Family members also need to feed the child more water, because the child will lose a lot of water during fever, so as not to cause dehydration. If the child's temperature exceeds 38.5 degrees Celsius, oral medication is needed to cool down.
