A cool, comfortable room is often essential for a good night’s sleep, especially in a hot and humid country like Singapore. Most households rely on air conditioners to create that ideal sleeping environment. But what if your trusty aircon is actually interfering with your rest instead of improving it? The relationship between air conditioning and sleep quality is more complicated than it seems.
Understanding how temperature impacts sleep
Your body temperature naturally drops slightly at night to initiate sleep. This cooling of the body helps to trigger melatonin production, a hormone that promotes sleepiness. If your room is too warm or too cold, it can disrupt this process, making it harder to fall asleep or stay asleep.
In Singapore’s climate, where average nighttime temperatures rarely fall below 25°C, air conditioning becomes more than just a luxury. It can make a real difference in creating a sleep-friendly environment. However, incorrect use of the aircon, such as setting the temperature too low or not servicing it regularly, may lead to restless nights.
Why a poorly maintained aircon could be the culprit
An aircon that hasn’t been properly serviced may emit strange noises, blow stale or dusty air, or fail to maintain a consistent temperature. All these issues can lead to discomfort, dryness in the throat or skin, or allergic reactions — all of which disturb sleep.
If you notice that your sleep quality worsens when the aircon is on, it might be time to schedule a professional inspection. A clogged filter or dirty coils can lower the air quality and force the unit to work harder, creating unnecessary noise. Singaporeans who value their rest should consider routine checks. Knowing the aircon servicing price upfront helps plan these checks without surprises.
Humidity control matters more than you think
Apart from cooling, air conditioners also dehumidify the air. Excess humidity in the room can make it feel warmer and more uncomfortable, leading to frequent tossing and turning at night. On the other hand, if the air is too dry, it can cause dry skin, irritated eyes, or even nasal congestion.
Finding the right balance is key. Aim for a room humidity level of around 50 to 60 per cent, which is generally comfortable for most people. Some modern units come with built-in humidity control, but even basic models, when used wisely, can help you find that sweet spot. Keeping your aircon well-maintained ensures it continues to function efficiently in this regard.
Setting the right temperature for sleeping
Many people believe that turning the aircon down to 18°C will lead to better sleep. However, studies show that the ideal temperature for sleep lies between 24°C and 26°C for most people. Going too cold can actually disrupt your REM cycle, which is crucial for feeling refreshed in the morning.
For those who tend to wake up feeling chilly or with a dry throat, consider setting the aircon on a timer or using sleep mode if your unit has one. This allows the temperature to gradually adjust overnight, supporting your body’s natural rhythms.
Smart habits to improve sleep with aircon use
Even with the best air conditioning unit, poor habits can interfere with sleep quality. Here are some tips to make the most of your aircon at night:
- Keep the filters clean to ensure fresh airflow
- Close windows and doors to maintain consistent cooling
- Use blackout curtains to reduce heat transfer from outside
- Avoid setting the fan speed too high to minimise noise
- Place the unit or vents away from directly blowing on your face
If your current system lacks features like sleep mode or humidity control, it might be worth exploring a new aircon installation that better supports restful sleep. Newer systems are often quieter, more energy-efficient, and better at maintaining a stable environment.
When is it time to re-evaluate your aircon setup?
You don’t have to put up with sleepless nights due to a noisy or ineffective aircon. If you find that sleep improves noticeably when the unit is off, or when you sleep in a room with better air quality, it’s a strong sign that your current system isn’t supporting your health.
Upgrading to a modern aircon or simply improving your maintenance routine can bring about significant improvements in your sleep quality. Regular servicing helps detect potential issues early, improves energy efficiency, ensures a longer lifespan for your unit, and enhances the comfort of your sleeping environment.
Sleep is vital to overall well-being, productivity, and mood. Making sure your aircon works for you — not against you — is a smart step towards better rest.
