A body temperature of 37.3°C is normal for newborns. There are three ways to take a newborn’s temperature: anal measurement, oral measurement, and axillary measurement. Anal measurement: This measurement method is very suitable for newborns. Because newborns are so small, it is inconvenient to take their temperature. Therefore, many people use the anal area to take the temperature of newborns, which takes only about 1-2 minutes and is very convenient. This time the thermometer reading is the temperature of the newborn’s body, and will be different from the temperature measured in the armpit. Oral measurement: The disadvantage of this method of temperature measurement is that it is not safe enough and is generally suitable for older children. The child is required not to speak or breathe through the mouth while the temperature is being taken, and the thermometer needs to be placed in the child’s mouth under the tongue. This method takes a relatively long time to take the temperature, 3 to 5 minutes, and the child must be patient. Underarm measurement: This method is the most common and most frequently used in life. However, it takes a longer time to take the measurement, requiring more than 5 minutes. If the time is short, there may be a difference between the measured skin temperature and the human body temperature. The normal body temperature of a person is not fixed and will have a range of variation. As long as the measured temperature is between 36.5 and 37.5 degrees Celsius and does not exceed 38 degrees Celsius there is no need to specifically go for medication.
