Infants’ body temperature of 36.1 degrees Celsius is normal, and the normal body temperature is 36-37.1 degrees Celsius. In addition, infants are young and their thermoregulatory centers are not yet well developed, so they are susceptible to changes in the temperature of their surroundings, so it is important to pay attention to the appropriate temperature of the surroundings and the right amount of wrapping. Temperature monitoring can only be used as one of the monitoring of vital signs, and not as the only indicator of whether the baby is sick or the severity of the disease. Therefore, in addition to normal body temperature, we must pay attention to observe whether the baby has mental atrophy, loss of appetite, skin rash, etc. If there is any of the above performance, even if the temperature is normal, we should take the baby to the hospital in time to avoid delaying the disease.
