You can consider using ice for physical cooling of fever, but you need to pay attention to the correct method of use, ice can be wrapped in a towel and then placed on the forehead area, but also on the back of the head area, as an ice pillow to assist in cooling. It should be noted that it should not be placed for too long at a time, up to about 10 minutes, to avoid frostbite. Especially for children with low immunity, it should be placed for a maximum of about 5 minutes at a time, if it is placed for too long, it is not good for the child. It is also important to note that physical cooling can only be used to deal with low fevers. If the fever persists above 39 degrees, it must be treated promptly with medication, such as ibuprofen or paracetamol and other antipyretic and analgesic preparations, as well as with cephalosporins or penicillin for anti-infection treatment. During fever, you should also pay attention to ensure adequate nutrition and drink more hot water. When the weather changes, you must pay attention to increase clothing in time to avoid getting cold and wind.
