Most people like to adjust their AC settings when they’re sleeping. We suggest programming your thermostat to gradually lower the temperature as you approach bedtime.
There is no definitive best setting for sleep temperature as it can vary from person to person. But in general, the recommended bedroom temperature for sleep is around 18.3°C. Doctors also recommend a range of 15.6°C to 19.4°C to get the most comfort in sleeping.
These recommendations are based on the fact that the human body will experience slight dips in the core temperature during the night. Lowering the thermostat at night may help your body regulate temperature and give it the signal to sleep.
However, you should note that these temperature recommendations only apply to adults. Children and infants will need a warmer temperature for comfortable sleep. However, don’t make it too warm as it may increase the risk of sudden infant death syndrome. For infants, 20.5°C is recommended.
