Sleeping with your window open has been proven to improve sleep quality, efficiency, depth and reduce awakenings.
A Dutch study found that people sleeping in a room with either the window or a door open slept better then those who didn't. It is speculated that the improved airflow allowed into the room from a window or door being open reduced the build up of CO2 levels and allowed a better quality of sleep.
In other studies subjects in well ventilated rooms have reported feeling better rested than their counterparts, as well as performing better when tested and having a better mental state. One study found that ventilated sleepers were able to fall asleep faster. However downsides of sleeping in a better ventilated room include mouth and skin dryness.
Obviously sleeping with your window open in winter can be a bit cold so leaving your bedroom door open during the colder months could be seen as a suitable alternative as it will allow increased airflow into your bedroom.
