Should I sleep with the aircon on?

It can be difficult to sleep in the humidity of an Auckland summer night. One way to cool down during the day is with a great aircon system, but have you ever wondered if it’s safe to sleep at night with the air conditioner on? While air conditioning undoubtedly brings many benefits, such as purifying the air in your home, some people worry about having their aircon on constantly. We’re here to inform you of the truth about air conditioning and how to utilize it best.

Is it bad to sleep with air conditioning? 

Scientists and experts all categorically agree that leaving the air conditioner on overnight is safe. Many go as far as recommend it to achieve an optimal temperature for sleep to help you fall asleep quicker and be more comfortable throughout the night. There are several things to consider in order to get a good night’s sleep. Air con can help filter air. To keep your air conditioning cleaning your room from dust and germs, make sure your filters are clean for healthier air.

Does the air conditioner improve sleep?

The reason experts recommend sleeping at cooler temperatures is because it can improve sleep. Falling asleep in the heat is almost impossible. Tossing and turning cause restlessness and it’s hard to relax when you’re too hot. Also, your body won’t have to wake you up when it gets too hot.

Can I leave the air conditioner on overnight?

Whilst it can help you to fall asleep and have a better sleep, there are a few pointers that can help.

  • Don’t have the aircon blowing on you directly, rather cool the room more naturally over time.
  • When you are asleep your heart rate is slower and your body temperature drops. It is also cooler at night than during the day, so set your aircon slightly higher than you’d normally have it.
  • Opt for a unit with a timer from us to schedule the air con to turn off when you will fall asleep to save on energy and not disrupt your sleep with the noise of operation.
