Normal body temperature in children aged 7 to 10 years is usually referred to as axillary temperature, which is usually between 36°C and 37°C. The normal range will vary if the temperature is taken orally or rectally. The methods of temperature measurement can be categorized into oral, rectal and axillary thermometry, and the normal body temperature ranges obtained from these three methods are different. Axillary thermometry is the most widely used method, with a normal body temperature range of 36°C to 37°C. Oral thermometry has a normal body temperature range of 36.2°C to 37.2°C, while rectal thermometry is more accurate, with a normal temperature range of 36.5°C to 37.5°C. If the child’s body temperature is not the same as that of the other methods, it is not possible to determine the normal temperature. If a child’s temperature is not within the normal range, it is recommended that he or she should go to the hospital in a timely manner to clarify the cause of the illness and receive treatment under the guidance of a doctor.
