In clinical diagnosis, methods to measure body temperature include oral, rectal, and armpit temperatures. For newborns, the armpit temperature is used as the baseline, with a normal range of 36~37 degrees. Newborns have greater body temperature fluctuations, with the lowest temperature in the morning and the highest in the evening. When a child has a low fever, parents can use a cold towel to apply cold compresses to the child’s forehead to reduce body temperature. Finally, during the treatment period, patients need to have a regulated diet, maintain a regular lifestyle, actively participate in physical exercise, adjust physical and mental health, and maintain personal hygiene to avoid bacterial invasion due to decreased resistance.
