Children with a temperature of 38.5 degrees are considered to have a fever and should promptly reduce the clothing they wear and be in a cool, comfortable and ventilated environment. Drink plenty of water in moderation to avoid dehydration due to fever. When you have a fever, if your hands and feet are cold with chills, you can soak your hands and feet in warm water, or take a warm bath. If you are in good spirits, have warm hands and feet, and do not have chills when you have a fever, you can use an ice pack or ice cubes to apply cold compresses to your head. If the body temperature is greater than or equal to 38.5 degrees, oral antipyretic drugs, such as ibuprofen and acetaminophen, should be given orally in appropriate doses according to body weight in a timely manner. Take your child to the hospital promptly and ask the doctor to help find the cause of the fever and provide effective treatment for the cause.
