There are pros and cons of sleeping in aircon room. The lower room temperature created by the aircon makes the room more comfortable to sleep and therefore induce deeper and better sleep throughout the night. With better sleep, you have better rest and would feel more recharged and energetic the next day. Some studies even conclude that sleeping in aircon room promotes the growth of healthy fats and reduce the risk of diabetes and other metabolic problems. However, further study may be necessary to confirm such direct health benefits.
On the other hand, sleeping in an aircon room also has its negative effects. If you do not have a humidifier, the air in the room may become very dry and this leads to dry itchy skin, sore throat and crack lips. If the aircon is tuned to very low temperature, you may catch a cold too. Find out what is the the ideal aircon temperature in a room.
Your aircon must also be well maintained to ensure that the bacteria accumulation in the aircon is under control and the filter is working properly. Otherwise, the air you breathed in will also be contaminated. Perhaps an air purifier may help in this case to clear up air contaminants in the room. However, air purifier is not a substitute for proper maintenance of aircon. Both maintenance of aircon and air purifier should be in place for best air condition. You should also maintain your air purifier. Find out more about aircon maintenance and air purifier.
How about babies? Should they be sleeping in the aircon room?
Babies sleeping in the aircon room is fine as long as the aircon is well maintained. In the Singapore hospitals, babies are also sleeping in the aircon room. Aircon keeps the baby dry and cool and may prevent nappy and heat rashes usually associated with Singapore hot and humid climate. However, you should ensure that the aircon is not blowing directly at the baby and the temperature is not set too low because babies may catch a cold easily. As air in the aircon room is dry, you may wish to keep the baby well moisturized.
