Can newborns lie in air conditioning?
Due to their delicate nature, many hesitate to use air conditioning for infants in the summer. They often dress the baby in multiple layers and use extra blankets for protection.
According to doctors, full-term, healthy newborns weighing 3.5 kg or more have enough body fat to regulate temperature. The thermoregulation mechanism is active, allowing babies to sleep in a cool, well-ventilated environment.
However, for premature babies weighing less than 3.5 kg, parents may consider waiting 1-2 months before using air conditioning.

Using Air Conditioning for Newborns in Hot Weather
When using air conditioning for newborns in hot weather, parents should consider the following issues to ensure the baby's safety:
1. Adjust the air conditioning temperature to 26 – 28 degrees Celsius
For full-term babies, the normal body temperature is around 36.5 – 37.5 degrees Celsius. If the baby is dressed in clothes, wearing socks, mittens, a hat, and covered with a blanket, the ideal room temperature for air conditioning is between 26 – 28 degrees Celsius.
Maintaining a room temperature above 28 degrees Celsius can make the baby sweat, develop rashes, become restless, and have difficulty sleeping. Therefore, parents need to adjust the temperature appropriately.

2. Avoid directing the air conditioning breeze directly onto the baby
The respiratory system of newborns is highly sensitive. If the air conditioner's fan blows directly onto the baby's head or face, infants with weak immune systems are susceptible to respiratory illnesses such as bronchial problems, bronchitis, nasal inflammation, and pneumonia.
The air conditioner should be positioned high in the baby's room, and its air vents should not face directly towards the infant. It is advisable to set the fan mode to rotate and the fan speed to the lowest.
3. Avoid letting newborns lie under the air conditioner for more than 2 – 3 hours at a time
Mothers should limit the baby's time under the air conditioner to 2-3 hours, followed by opening the room door and allowing the baby to experience normal temperatures for 10 – 15 minutes. When going outside, parents should open the door wide, pause for about 2 – 3 minutes to allow the baby's body to adapt to the external environment, preventing heat shock.

4. Avoid suddenly taking the baby in/out of the air-conditioned area
While the baby is in the air-conditioned room, parents should avoid abruptly taking the baby into the outside environment. Sudden temperature differences can lead to heat shock, resulting in fever, colds, and coughs.
When planning to take the baby outside, mothers should turn off the air conditioner and let the baby sit in it for a while to gradually increase the room temperature, helping the baby adapt more easily. When the room temperature is close to the external temperature, mothers can confidently take the baby outside.
Conversely, when the child comes in from the heat and sweats a lot, mothers should wipe the sweat off the child and let them rest for at least 3 minutes at normal room temperature. Avoid immediately placing the baby in the air-conditioned room with cold air and a sudden drop in temperature.
5. Maintain body moisture
Lying under the air conditioner provides a cool sensation but can easily cause dry skin and a dry nose. Therefore, mothers should pay attention to using saline solution, encourage the baby to breastfeed more to avoid dehydration.
When the baby sleeps, use a thin blanket to cover the abdomen, avoiding open pores that can lead to a chill. Change wet diapers promptly to prevent the baby from getting cold. Use suitable moisturizing cream for the baby, place a bowl of water, or use a humidifier in the room.

6. Regularly clean the room and air conditioner
Keep the air conditioner clean to avoid dust and bacteria accumulation that can affect air quality. Maintain a clean room to prevent bacteria infiltration that could impact the baby's respiratory system.
Appropriate Air Conditioning Modes for Newborns
Air conditioner brands have equipped their devices with modes suitable for newborns, including:
