The normal value of infant body temperature is slightly different according to different measurement methods, different measurement positions and different environments, and the normal range is roughly between 36℃ and 37.5℃.
The normal range of temperature for infants is between 36.0°C and 37.2°C when the axillary temperature is measured with a mercury needle thermometer. Using infrared ear temperature measurement, the normal range is between 36.5 and 37.5°C. If rectal thermometry is used, the normal range is between 36.5~37.5℃.
Because the infant’s temperature center is not fully developed, the body temperature is susceptible to interference by external factors, such as infants just after crying, after eating or playing more excitedly, the body temperature may be higher than the normal value of 0.2 ~ 0.4 ℃.
When the temperature of the infant’s environment is high, the body temperature may reach about 37℃. If the infant’s environment is too low, the body temperature may also be low, about 36℃.
Parents are advised to measure the temperature of their infants when they are quiet and in a suitable temperature environment. If the infant’s temperature is above or below the normal range, it is necessary to actively seek for the cause and intervene.
