The temperature of an infant can be measured in three areas, oral, anal and axillary, with the axillary temperature generally being the most commonly used measurement. Usually, an axillary temperature between 36 degrees Celsius and 37.3 degrees Celsius can be considered normal. Above this body temperature, it is considered feverish. Below this temperature, it is considered hypothermia. For example, it is best to avoid half an hour after eating, or just after drinking hot water, because just after eating will produce a special dynamic effect of food, will produce heat, the measured temperature may be high, and drinking hot water directly brings heat into the body, of course, like physical warming, will bring some changes to the body temperature. In addition, if the measurement is the axillary temperature, you also need to dry the armpits, otherwise it will also affect the results of the test. In addition, the measurement application is the mercury thermometer or other thermometer also has a certain impact, at present or mercury thermometer prevails, but in practice there is a real risk of mercury contamination, must be more watchful baby to avoid breaking or accidental ingestion. In short, there is a range of normal body temperature, normal body temperature also depends on the location of the measurement, the application of the measurement of things, whether to circumvent the considerations affecting the determination of body temperature.
