The Link Between Air Conditioning and Sleep Quality.

The quality of sleep is influenced by various factors, including the sleeping environment. Temperature and indoor air quality play a significant role in regulating sleep patterns and ensuring a restful night’s sleep.

Maintaining an optimal sleep environment through proper air conditioning can have a positive impact on sleep quality. Let’s explore how temperature and indoor air quality can affect sleep patterns and delve into tips for creating an ideal sleep environment.

Temperature and Sleep Quality.

The body’s internal temperature is intricately tied to the sleep-wake cycle, also known as the circadian rhythm. As you prepare for sleep, your body temperature naturally drops, promoting drowsiness and sleep onset.

Sleeping with air conditioning and a cooler bedroom temperature can facilitate this temperature drop and promote more restful sleep, especially during hot summers. The ideal room temperature for sleep typically ranges between 15.5 to 19.5 degrees Celsius.

Indoor Air Quality and Sleep Quality.

Indoor air quality can impact sleep quality as well. Poor air quality with high levels of pollutants, allergens, and inadequate ventilation can lead to discomfort, allergies, and even respiratory problems, all of which can disrupt sleep. Proper ventilation, air filtration, and humidity control are essential components of a healthy sleep environment.

Is It Safe Using Air Conditioning Whilst Sleeping?

Sleeping with air conditioning being left on all night might be technically safe but there are a few things you should know and consider before doing so.


Body Temperature.

Your body temperature can drop between 1 and 2 degrees whilst you sleep, so you may feel more comfortable leaving your air conditioning on a low setting, rather than turning it up full blast before you sleep. Leaving your air conditioning on a low setting will also avoid you getting a chill.



Sleeping with air conditioning can dry out your room, making your nose feel stuffy and your skin feel dry. If this happens, you may want to cool your room down before going to bed and then turn the air conditioning off. Alternatively, you may want to try using a fan to cool down as well as other techniques, including keeping your curtains closed and your windows open, if there’s a breeze.

No matter whether you plan to use your air conditioning unit throughout the night or just at certain points during the day, the unit should be regularly cleaned. AC units that are not regularly cleaned can harbour a build-up of dust and dirt that can spread into your room once you turn it on.

Overall, there is no safety issue when it comes to leaving your air conditioning on all night, but you should be mindful of the possible issues that this could cause and take appropriate measures to make the most of your system. Also, be sure to understand how much energy this is using overnight and if it’s a necessity for you.

Tips for Setting the Ideal Temperature and Optimising Sleep Comfort.

Use Programmable Thermostats:

Programmable thermostats allow you to set the temperature to gradually decrease as bedtime approaches, ensuring that your sleep environment is conducive to falling asleep. You can also program the thermostat to increase the temperature in the morning, aligning with your waking time.

Programmable thermostats are also crucial for helping to reduce energy consumption of your air conditioning system. Be sure to click the link if you would like to find out more on efficiency upgrades for your HVAC system!


Create a Cool Sleep Environment:

Ensure that your bedroom is well-ventilated and properly insulated. Use breathable, lightweight bedding materials that can help regulate body temperature. Consider using a fan in conjunction with air conditioning to enhance air circulation.


Manage Humidity:

Maintain indoor humidity levels between 30% and 50% to prevent excessive dryness or dampness. High humidity can promote the growth of allergens and mould, while low humidity can cause discomfort.


Limit Light and Noise:

Use blackout curtains to block out external light, as light can interfere with the body’s production of melatonin, a hormone that regulates sleep. Similarly, minimize noise disturbances that can disrupt your sleep cycle.


Regular Maintenance:

Ensure that your air conditioning system is well-maintained, and its filters are changed regularly. This promotes good indoor air quality and efficient cooling. Discover our maintenance checklist and find out hoe to keep your system working efficiently this summer!


Experiment with Temperature:

While the general temperature range is 15.5 to 19.5 degrees Celsius, individual preferences may vary. Experiment with different temperatures to find what works best for you.


Consider Smart Thermostats:

Smart thermostats can learn your sleep patterns and adjust the temperature accordingly. Some models can even sync with wearable devices to optimize sleep conditions.


Prioritise Consistency:

Try to maintain a consistent sleep schedule and sleep environment, even on weekends. Consistency helps regulate your body’s internal clock and improves sleep quality over time.

Final Thoughts: Time to Sleep.

In conclusion, the link between air conditioning, temperature, and sleep quality is evident. By setting the right temperature, maintaining proper indoor air quality, and following these tips, you can create an optimal sleep environment that promotes restful sleep and contributes to overall well-being. Remember that individual preferences vary, so it’s essential to find what works best for you to achieve a good night’s sleep.
