Baby body temperature 37.1 ℃ in the range of normal body temperature, as long as the baby’s axillary body temperature does not exceed 37.5 ℃, are normal body temperature. Usually, the normal body temperature is generally 36 ~ 37 ℃, such as just an individual once the body temperature reaches 37.4 ℃, the general condition is good, and there is no self-conscious symptoms, is not morbid. 37.5 ~ 38 ℃ for the low fever, 38.1 ~ 38.9 ℃ for the moderate fever, 39 ~ 41 ℃ for the high fever, ≥ 41 ℃ for the ultra-high fever. The most common way to measure body temperature is axillary body temperature, and the baby’s temperature of 37.1℃ does not exceed the upper limit of normal axillary body temperature, so the baby’s body temperature is normal. And, due to the high temperature in summer itself, especially the temperature measurement at noon or after the child’s strenuous exercise, can cause the measurement of the degree of high.
