What Is The Best AC Temperature For Sleeping At Night

Setting your AC temperature slightly higher than what you have the temperature set at during daylight hours is best suited for when you go to sleep at night. There are a few reasons from an experienced aircon service company why a temperature setting that is higher is considered better while you are sleeping.

1 Ambient Air Temperature

Even on very hot days as well as nights, the temperature outdoors will drop lower than the daytime temperature. When the outdoor temperature starts to drop, the indoor temperature will also start to gradually decrease.

This also means that an AC will find it easier to reach a desirable indoor temperature than it would during the day. Changing the aircon setting or thermostat to a temperature that is higher during the evening is suggested, especially before you go to bed. This will help you to save energy, which will favourably affect your electric bills.

2 Your Body Temperature

When you are active during daylight hours, you are busy and move around. This naturally causes the body to produce heat. In the evenings while you are sleeping, your normal body temperature will start to decrease. This is the reason why many people sleep under a blanket to keep warm and to maintain a consistent body temperature. The setting of your AC should reflect the changes to your body temperature. However, since your body temperature decreases gradually, you might feel slightly hot when you get into bed, and you may decide to drop the AC temperature setting. If you do this, you will probably find yourself waking up in the middle of the night when you suddenly feel cold.

Waking up unnecessarily causes disruptions to your sleep and even sleep deprivation. Studies have indicated that disrupted sleep can lead to weight gain (more common in women) and even contribute to developing type II diabetes.

For these health reasons, it is better to make sure your AC temperature is set higher before you go to sleep. This will stop you from waking up when you feel cold.

3 Dry Air

Cold air also translates into drier air, which also means that air in your room is drying out when you sleep. Warmer air translates into an increase in humidity which is much healthier for your respiration and your skin. If you wake up every morning with a very dry throat, mouth, and nose, it probably means your AC setting is too low and there is not enough humidity in your bedroom.

While a dry mouth, throat, and nose won’t necessarily make you sick, it will result in dehydration. Dehydration, while you are sleeping, can lead to different types of health consequences. Dryness can also make you more vulnerable to contracting a transmittable illness or disease while making your body more susceptible to an attack from bacteria, viruses, and other types of microorganisms.

To protect your nose, throat, mouth, and skin while you are sleeping, make sure your AC is set to a higher temperature, or when possible turn it off before you go to sleep.

What Is The Best AC Temperature While You Sleep?

25 degrees Celcius or Centigrade is considered a comfortable indoor temperature. This is also the recommended temperature to set your AC at when you go to sleep at night. If you feel like this setting is uncomfortable for you, here are two tips you can use:

• Turn your AC to a temperature that is lower in your room around 20 minutes before going to bed at night, and then adjust the temperature to a higher setting before you get into bed.
• Find a setting between 20 and 25 degrees Celsius that feels more comfortable to you. It is not suggested to run an AC on one of the lowest settings (between 16 degrees and 18 degrees) when you are sleeping at night.
  You can also choose to buy a new AC unit that comes with a Sleep Mode option or feature.

What Is Sleep Mode?

Sleep mode is an option available on many modern AC systems. This mode will increase the AC temperature incrementally. The process will start at a temperature that you have already set your AC at. The temperature will then increase between 0.5 and 1 degree every hour. The total increase in temperature is typically 3 degrees. This will mean that while your body temperature drops gradually, the AC temperature is also gradually increasing, which means you will be less likely to wake up when you feel too cold.

Here is an example:

If you set your AC to 20 degrees. Your aircon will increase by 0,5 degrees every 30 minutes during Sleep Mode. In 3 hours your AC will reach 23 degrees and you will be sleeping already. You won’t notice that the air temperature has increased, contributing to a better night’s sleep.

If you have an outdated AC that does not feature a Sleep Mode feature, it may be worthwhile to consider an upgrade. The aircon systems that do not offer a Sleep Mode, use outdated technology, use too much energy, and will probably need to be replaced sometime soon anyway. If this is the case, do your own research on the latest models and makes currently on the market to give you an idea of the most modern features that these systems have to offer. This will help you to choose a model that matches your budget and your needs.
