Sleeping with Air-Con: Is It Safe? You Might Not Like The Facts

Did you hear about how Singapore’s temperature is going to rise by 9 degrees Celsius? That’s like the end of the world.

But luckily, we can take comfort in the cool air of air conditioners. Many of our homes already have ACs installed. And most of us sleep with the AC on.

But is that safe? You’ll be surprised.

It can affect your immune system
During the night, your body cools down naturally. With low temperatures, your body might be too cold and that could affect your immune system. In addition, your body cannot produce important hormones that help improve your immune system effectively.

It leaves you dry and dehydrated
Sleeping all night with the aircon on will leave your skin and throat feeling dry. Cold air can also cause illnesses like chest pain, bronchitis, and sore joints.

It can make you fall sick
The dry air that your aircon unit blows into the room might contain germs and bacteria. Imagine breathing these same germs and bacteria in throughout the night, especially if your AC unit is not well maintained!

It might lower your risk of diabetes
Say what? Yup, that’s right. If you do sleep in an air-conditioned room every night, just ensure it’s not too cold. Sleeping in cooler temperatures can produce active fats that remove sugar from your blood and burn calories.

Best temperature is 23 degrees Celsius
If you really need to sleep with the AC on, leave it at this temperature. It’s not too cold, and it sure is cooler than without an AC.

This will ensure that you don’t end up with a bad dry cough or sniffing noses when you wake up in the morning.

So, still thinking of sleeping with the AC on? Just use a fan instead. It’ll save you some – or I should say, a lot of – money, too.

But let’s face it: how many of us can sleep without air-con?
