Children’s temperature of 37 ℃ is generally a normal body temperature, but attention should be paid to dynamic monitoring, there is no persistent elevation or incorrect measurement of body temperature. Children’s normal body temperature range is: axillary temperature of 36.0 ℃ ~ 37.2 ℃, anal temperature of 36.5 ℃ ~ 37.5 ℃, oral temperature is generally higher than the axillary temperature 0.2 ℃ ~ 0.5 ℃. Therefore, the child’s temperature 37 ℃ is a normal temperature, but because it is in the normal range of critical value, it is recommended that the dynamic and correct measurement of body temperature. Children’s thermoregulatory center is still not well developed, can be measured after activity, crying or breastfeeding temperature is high, so the measurement process should avoid the above factors, so that the results of the temperature measurement is more accurate. For some children, a persistent increase in body temperature, such as over 37.5℃, suggests that the child is in a state of illness, which is not normal. Consultation with a specialist is recommended when necessary.
