We all know that getting a good night’s sleep is crucial to our wellbeing — health benefits include weight control, brain function and athletic performance among others. But did you know that the temperature in your bedroom can affect how well you sleep? Read on to learn the best air conditioner temperature for sleeping

Studies have shown that 18.3°C, give or take a few degrees, is the best air conditioner temperature for sleeping. This is because it helps to regulate your internal body temperature and syncs to your circadian rhythm (sleep cycle). You’ll fall asleep faster and sleep deeper, vastly improving your quality of sleep. One thing to consider is setting low temperatures (anything below 24°C) on your air conditioner combined with Queensland’s high humidity can result in condensation forming on your ductwork & grilles.

NOTE: We suggest consulting your HVAC professional prior to running temperatures below 24°C on your air conditioner.

Most people experience abnormal sleeping patterns during the hotter summer months when it’s harder to keep the ideal room temperature.

Humidity can also cause sleeping disruptions, something that many Queenslanders are all too familiar with. While it doesn’t change the temperature, it affects how your body perceives it — hot air with high relative humidity makes the evening feel muggy.

How does too hot and too cold vary?

Temperature affects us differently on either side of the scale.

Rooms that are too hot can cause restless sleep due to a decrease in your slow-wave sleep or rapid eye movement (REM) sleep.

Being too cold may make it harder to fall asleep and result in tossing and turning throughout the night. But this can be counteracted by additional blankets, bedding or heating.

Take control of bedroom temperature and humidity

Stop tossing and turning by controlling these two key factors – humidity and temperature. If your bedroom is too hot, humid or stuffy then it’s time to take control by adjusting them with air conditioning.

This way you’re killing two birds with one stone. You alleviate discomfort and restlessness. Plus you’re also removing odours and protecting yourself from viruses, allergens and harmful VOCs with air purification.

4 Factors to consider when selecting an AC unit for the bedroom

Sleep is vital for your physical and mental health, so the more you can do to create a sleep conducive environment, the better.

Before you pick an AC unit, you should weigh up The Pros and Cons of Zoned Air Conditioning. There are a number of advantages and it is the most efficient cooling method for a large home, which is great for your energy bill.

If you opt for Split System Air Conditioning, here are a few tips to choose the perfect AC unit for the bedroom.

  • A smaller – 2.0 – 3.5kW – wall mounted split system unit is generally sufficient for a bedroom but the size of your room will determine the output you need. You can consult with Smarter Air to work out the ideal size.
  • Check the technical specifications for sound levels. Low modes can be as little as 19dB which is quieter than a whisper.
  • Opt to place the AC unit on the left or right-hand side of the bed or on the opposite facing wall, rather than directly over the bedhead. This helps distribute cool air evenly without blowing directly onto you.
  • Flickering lights can be distracting when trying to fall asleep so opt for a unit with a brightness adjustment function for any LED lights.

We just had our unit installed a few days ago and wow...what a difference it has made. The process was so easy from start to finish. Alex was happy to run us through every system until we found exactly what we needed. The officecwas a pleasure to deal with. The installers, led by Ben were so considerate and professional and took such great pride in their work. I can't thank Ben and his team enough. They did a brilliant fit out, cleaned so thoroughly and explained all the tech so simply. I truely recommend these guys and hopefully you get Ben and his team for your fit out.

We cannot rate this company enough! Louis, Jayden, Aidan and Wayne were awesome, really professional and treated our home brilliantly whilst installing the ducted aircon and removing two opd split systems. The ducted system itself is so much more efficient than the two split systems we had. This company was great to deal with from the start at the quote phase, to site visit and all the way to the installation part. 5 stars. Would recommend.

We had ducted air conditioning installed and the entire experience was excellent. From the initial quote to the final install, communication was clear and honest and this close to Christmas extremely efficient service. The installers were professional, efficient, and were extremely polite and well mannered on site. The system runs quietly and cools the house perfectly. Would highly recommend to anyone considering ducted air from Smarter Air & Electrical.

My husband and I can't speak highly enough about the team from Smarter Air & Electrical. Great communication and information from Alex in sales. Jack who came to quote and do the site inspection was such a nice guy and was so helpful. On the day of installation, Haydyn and his team arrived right on time. They did an amazing job and left everything so tidy and clean when they left. We were so impressed with how professional the whole team was. We would highly recommend this company if you're looking for a ducted air conditioning system. Thanks guys!

Absolutely fantastic experience from start to finish. From receiving a quote with multiple options and add-ons providing transparency and accurate figures for pricing. The initial site visit occurred quickly. After this we had an initial install date booked which I had to change and Smarter Air were extremely accommodating with a date change. On the day of installation, Joey and the team arrived on time, completed the job to a fantastic standard, left the house very clean, and explained how everything worked. All the guys who worked on the job were absolute champions. Best experience.

Absolutely fantastic experience with Smarter Air & Electrical. From the first site visit, Ben (legend) was friendly, knowledgeable, and great to deal with. No sales pressure at any point—just honest advice, clear communication, and a genuine focus on what suited us best. The whole process was smooth and well-organised, with everything running on time and as promised. On installation day, Phil (one of the directors) was on-site to double-check plans and talk through any technical details or adjustments which was a great touch and showed how much they care about getting things right. The team was respectful, efficient, and left everything tidy. They clearly take pride in their work. The result is brilliant—clean install, great system, and total peace of mind. Highly recommend them for a stress-free, professional experience.

Amanda told me she was sending her best tradie, Ben, who was punctual, professional, and polite. Ben, ensured the job was turned out as if it was work on his own home, and then educated my wife on the operation of our new aircon. In short, Ben is an LBW, ( living bloody wonder) and an asset to the business, and his offsider, Sam, a good bloke, with 2 ears, both of which seem to work.
