The Role of Air Conditioning in Improving Your Sleep Quality

Author Rod Marchant-Smith | Peninsula Air Conditioning

Sleeping in a comfortable environment is the key to getting a good night’s rest. Hot, stuffy rooms can make sleeping comfortably impossible, leading to tossing and turning all through the night and a grumpy mood in the morning. 

If this sounds all too familiar to you, it may be time to consider installing an air conditioner. 

Does Air Conditioning Improve Sleep Quality?

Air conditioning plays a vital role in creating a comfortable environment, especially during the warm summer months. With the ability to regulate the temperature and humidity levels in your bedroom, air conditioning enables you to create the ideal environment to help you fall asleep faster and stay asleep longer.  

How Does Air Conditioning Affect Air Quality?

Good, clean air is essential for a healthy sleep environment. Luckily, in addition to cooling the room, most air conditioning units also work to filter and improve the air quality of the room. Air conditioning units are typically equipped with filters that remove dust, pollen, pet dander, and other allergens from the air, reducing the risk of respiratory irritations and allergies that can disrupt sleep. Air conditioning also helps to reduce humidity levels and prevent mildew or mould from developing. This helps to avoid respiratory issues from developing and ensure uninterrupted sleep.

What’s The Best Temperature For Sleep?

The optimal temperature for sleeping can vary from person to person, so it’s best to play around with the AC temp at night to see what works for you. Finding the ideal temperature for your bedroom is essential for a good night’s sleep, so you may need to experiment with different settings over the course of a few days to a week.

If you’re looking for a starting point, The National Sleep Foundation suggests that, for most people, the best ac temperature for sleeping falls within a range of 17 to 19 degrees Celsius.

What Is The Sleep Function Of An Air Conditioner? 

Many newer air conditioner models now feature a ‘sleep function’ to help conserve energy while maintaining a comfortable sleeping environment. This feature adjusts the cooling settings by gradually raising the temperature or adjusting the fan speed over the course of the night. Most people typically struggle most with falling asleep due to discomfort, rather than staying asleep. The sleep function works with the body’s natural cooling needs during sleep to ensure a restful sleep while limiting excessive cooling or energy waste throughout the night.

Tips For Using Air Conditioning While You Sleep

If your air conditioner doesn’t have a ‘sleep mode’, you may be wondering how to use AC at night without wasting energy.

While a little more involved than sleep mode initially, a programmable thermostat is a great alternative. A programmable thermostat allows you to schedule temperature adjustments, ensuring your bedroom is cool and comfortable by the time you go to bed, and adjusting the temperature a little once you’re asleep to prevent energy waste.

It’s also important to make sure your air conditioning vents aren’t obstructed by any furniture or curtains, as this could interfere with temperature distribution or effective airflow throughout the room.

What’s The Best Air Conditioner For The Bedroom?

There are a range of options when it comes to selecting an air conditioner for your bedroom. Split system air conditioners are a popular choice for bedrooms as they offer quiet operation and are easy to control, while ducted air conditioning systems or multi-split air conditioning systems are a great choice if you’re looking for a cooling solution for the whole house. There are also a range of small air conditioners for bedrooms on the market that provide both cooling and dehumidification functions. 

Whichever air conditioning system you select, it’s important to enlist the help of an experienced air conditioning technician for proper installation and regular maintenance checks. 


Creating a comfortable environment is the key to getting good quality sleep. With the help of air conditioning, you can regulate the temperature and humidity of your bedroom, filter out dust and allergens, and wake up feeling rested and rejuvenated.
