Newborns can be air-conditioned, but it is necessary to adjust the temperature of the air conditioning suitable for newborns, keep the indoor air clean and avoid placing newborns in the vent. 1. Adjust the appropriate air conditioning temperature: newborns are not mature enough to regulate their body temperature, too high or too low air conditioning temperature will have a negative impact on the growth of newborns. When the temperature is too high, newborns are prone to rashes and mental lethargy due to high body temperature. When the temperature is too low, the newborn may appear hard swelling of the skin, respiratory tract infection and other symptoms. 2. Avoid direct blowing from the air vents: the wind is stronger in the air vents and the temperature is lower or higher than in other places, placing the newborn in the air vents will cause the child’s body temperature to change more. 3. Indoor air to keep clean: air-conditioned rooms more closed doors and windows, long time without ventilation will make the room air quality decline, easy to breed bacteria and other pathogens, the baby is prone to infections. Therefore, air-conditioned rooms should be ventilated regularly by opening windows. Under the premise of paying attention to the above problems, newborns can blow the air conditioning, and at the same time need to pay attention to warmth, to avoid catching cold.
