If your child has a fever that stays around 38°C, it is considered a low fever and does not require fever-reducing medication. Only if the body temperature exceeds 38.5℃, it is necessary to use ibuprofen or acetaminophen to reduce fever. Physical cooling should be chosen when the body temperature is 38℃, and you should drink more water and increase the amount of fluid intake. You should also wipe your forehead, neck, armpits and groin with warm water, and keep the end of your extremities warm. If the end of the extremities are cold, you must keep them warm in time so that the body temperature does not go up. You can also take oral herbs that have a clearing effect on heat, such as pediatric Chai Gui antipyretic granules. If the child’s body temperature is always 38℃, but the mental state and feeding are very good, it can be observed clinically. If the child’s mental state is not good or accompanied by other symptoms such as cough, vomiting, diarrhea, as well as poor feeding and reduced urine output when the fever is 38℃, it is necessary to go to the hospital for consultation.
