The indoor air-conditioning temperature that is most suitable for infants’ life should be kept within 26~28℃. The thermoregulatory center of infants who are just born or a few months old is not fully developed, and their own thermoregulatory ability is relatively poor and easily affected by the external environment. Air conditioning temperature control within 26 ~ 28 ℃, the baby’s body is the most comfortable. If the air conditioning temperature is too high, it will affect the distribution of heat in the infant’s body, which may lead to an increase in the infant’s body temperature; if the air conditioning temperature is low, the baby’s body temperature may subsequently drop. In addition, if the outdoor temperature is too low in winter, the air-conditioning temperature can be raised appropriately. Therefore, it is recommended that the indoor air-conditioning temperature be maintained within 26 to 28 ℃, but also pay attention to more open windows and ventilation to avoid air pollution.
