There is nothing wrong with a fever of 38℃ for one night. If the body temperature is below 38.5℃, it is still a case of low fever, so you don’t need to deal with it deliberately, you can use physical cooling methods, and the effect of fever overnight is not very big. This time you can use a warm towel to wipe the skin of the patient’s whole body, especially the armpits, groin, neck and other places rich in large blood vessels, the wiping time can be slightly longer, for a better effect on reducing fever. However, if it is for infants and young children, who usually have a history of febrile convulsions, a fever of 38 degrees Celsius a night, it is likely that febrile convulsions will occur. This time it is best to give your child antipyretic drugs in advance, to avoid repeated high fever convulsions, which can produce irreversible damage to the child’s brain cells, you can give your baby ibuprofen suspension or acetaminophen pellets to reduce fever, the interval of 4-6 hours can repeat the medication once, no more than 4 times a day.
