The best temperature for newborn babies is between 23°C to 26°C. They should be kept in a comfortable and healthy environment. Infants should live in a suitable temperature that may not be the same for adults. Parents who use air conditioners often ask us about the right temperature for newborns. Let’s explore this in detail.
Ideal Aircon Temperature for Newborns
The recommended room temperature for newborns is between 23°C to 26°C. This temperature is recommended by Health Hub ( national platform for digital health in Singapore). This range helps your baby stay cool without the risk of getting too cold.
If we consider tropical countries like Singapore, its not always possible to keep indoor room temperature below 30 degree Celsius without an aircon. Using aircon is not only safe in such conditions but helpful—if used correctly.
Why 23°C to 26°C?
Below are the reasons why 23°C to 26°C is safe for newborns:
- Below 23°C, babies may feel cold, especially since they can’t regulate their body temperature well.
- Above 26°C, babies may feel hot and become restless or sweaty.
- The middle point, around 25°C, is often the most comfortable.
Use a Fan with Aircon For Better Newborn Comfort
You can use aircon alone to cool the room. However, using a fan with an aircon can also be effective for below reasons:
- Distribute cool air evenly
- Prevent hot or cold spots
- Improve ventilation
Make sure the fan is not blowing directly on your baby.
Dress Your Baby Properly
What your newborn wears makes a difference. Here’s how to dress your baby for an air-conditioned room:
- Use a short-sleeved cotton onesie or sleepsuit.
- Swaddle lightly if your baby is below 2 months.
- Avoid overdressing—if you need a blanket, make it light and breathable.
- Always check your baby’s chest or neck, not hands or feet, to assess warmth.
Tips to Use Aircon Safely
Here are some useful tips for using aircon for your newborn at home:
- Pre-cool the room: Run the aircon 10–15 minutes before bedtime, then adjust to your desired temperature.
- Regular servicing: Dirty filters can cause cough or allergy. Clean them every month and service the unit every 3–6 months.
- Avoid direct airflow: Position the cot or crib away from the direct path of the cold air.
- Use a thermometer: Room thermometers help monitor actual temperature, not just what the remote shows.
- Don’t make the room too cold: Chilling the room below 23°C is not necessary and may make your baby uncomfortable.
Should I Use a Humidifier?
Air conditioning reduces humidity in the room, which can make the air dry. In Singapore, this usually isn’t a problem due to high moisture levels outdoors. But if your baby has dry skin or a blocked nose, you can consider a cool-mist humidifier in the room.
Aircon for Newborns: What Not to Do
Avoid these common mistakes:
- Setting the aircon below 22°C
- Dressing baby in thick clothes under the blanket
- Using aircon and closing all doors/windows without ventilation
- Letting baby sleep in the direct path of cold air
FAQ
What temperature is too cold for a baby in aircon?
Anything below 22°C is considered too cold. Your baby may become chilly, especially during long hours of sleep.
Can newborns sleep in an air-conditioned room?
Yes, as long as the temperature is set between 23°C to 26°C and your baby is dressed appropriately.
Is fan or aircon better for a baby?
Aircon is better for cooling the room, especially in Singapore’s climate. You can use both together for better airflow, but avoid direct drafts on the baby.
Should I leave the aircon on all night?
You can, but keep it at a stable temperature. Alternatively, cool the room before bedtime, then switch to a fan or set a timer.
Can aircon make my baby sick?
Cold, dry air from the aircon can cause mild discomfort or a stuffy nose, especially if filters are dirty. Keep the air clean and the room at the right temperature to avoid this.
