The baby’s body temperature generally refers specifically to the core temperature, if the body temperature of 35.5 degrees Celsius is too low, is not normal. Generally speaking, the human body temperature is divided into body surface temperature and body core temperature, clinically used over the armpit clamping armpit, to build a closed cavity, simulating the body core temperature, the baby’s body core temperature fluctuations in 36.0-37.3 degrees Celsius are normal. There are individual differences in human body temperature, related to age, emotion, etc.. But if it is the body surface temperature generally do not need to worry too much, for example, a long time to put the hand in ice water, may be the hand surface temperature of only 32 degrees, but this situation obviously can not be said to be abnormal. When the baby’s core temperature is lower than 36 degrees Celsius is hypothermia, may be due to the baby’s excessive heat dissipation or heat production is reduced due to the baby should give the baby more clothes to pay attention to keep warm. Infants due to the temperature center is not well developed, thermoregulation function is not complete, thermoregulation is susceptible to the influence of the surrounding environment, temperature fluctuations than adults, so parents should pay attention to the baby’s body temperature changes. The baby’s body temperature reflects the baby’s physical condition, the baby’s body temperature is too high or too low, need to be treated .
