In Singapore, where it’s warm and humid all year round, many people wonder — is it really necessary to sleep with the aircon on at night? While some prefer using a fan or natural ventilation, others can’t imagine getting through the night without the cool comfort of air conditioning.
In this post, we’ll explore the pros and cons of using aircon at night, why some people sleep better with it, and whether it’s truly essential for a good night’s rest. If you’ve ever asked yourself whether you should sleep with the aircon on at night, this guide is for you.
Is It Good to Sleep with Aircon On?
First of all, sleeping in a cool and comfortable room can help you fall asleep faster and stay asleep longer.
Singapore’s night temperatures often remain above 26°C, with high humidity making it feel even warmer.
Therefore, an aircon can help reduce discomfort, prevent night sweats, and improve sleep quality.
However, using an aircon the wrong way — like setting it too cold or skipping maintenance — can lead to dry skin, sore throats, or stuffy noses.
Benefits of Using Aircon at Night
Now, let’s take a look at why many people choose to turn on their aircon when sleeping.

Better Sleep Quality
Firstly, cooler air helps your body relax and makes it easier to drift off to sleep.
Studies show that people sleep better in temperatures between 24°C and 26°C.
Reduced Humidity
Next, Singapore’s high humidity can make nights feel sticky and uncomfortable.
An aircon not only cools the air but also reduces moisture, making your bedroom feel fresher.
Keeps Mosquitoes Away
In addition, mosquitoes prefer warm, humid environments.
As a result, using an aircon can help keep your room mosquito-free.
Downsides to Sleeping with Aircon
On the other hand, there are a few things to watch out for:
-
Dry skin or throat if the air is too cold or dry
-
Higher electricity bills if the aircon runs non-stop all night
-
Potential health issues if filters and coils aren’t cleaned regularly
But don’t worry — with the right habits, you can avoid these problems.
Tips for Safe, Comfortable Aircon Use at Night

✔️ Set the temperature between 24°C to 26°C
✔️ Use a timer or sleep mode to automatically turn it off or adjust the settings after a few hours
✔️ Keep your aircon clean and well-maintained to avoid health problems
✔️ Pair with a fan to circulate cool air and reduce energy use
By following these tips, you’ll stay cool, comfortable, and safe while saving on your power bills.
