Key ritual to do in your room to ensure best night's sleep possible every night

Every individual will find that they have their own unique methods to ensure they drift off to sleep easily - even ones that may be considered controversial.

However, the biggest debate of them all, which has circulated for years, is whether you should sleep with your window open or closed.

Thankfully, a new study has put the topic to bed after revealing the best option to ensure that a person achieves the perfect night's sleep - and it's not what you might think.

After conducting a study of 40 people to test their thinking skills, it revealed that those who slept with their windows open performed better and achieved a better night's rest.

Leaving your window open will ensure the room is better ventilated with fresh air, thus leading to a better night's sleep and improved thinking skills.

Researchers recruited 40 people willing to have their sleep tracked over the course of two weeks.

Those that slept with the window open did better in a mental ability test the following day compared to those that slept with their windows closed.

Research showed that in the first week, people slept normally, but results improved in the second week once they were asked to open their window and bedroom door if they normally had them closed. On the other hand, others were asked to close them if they were normally open.

Overall, according to results obtained from a sleep tracker, those who slept with the window open slept significantly longer.

As a whole, they made fewer errors in a three-minute test of their reasoning skills compared to those who slept with the windows closed.

Senior author of the study, Dr. Pawel Wargocki, from the Technical University of Denmark, explained: "The air quality in the bedroom can affect your cognitive abilities, such as your ability to concentrate, to understand, and to react.

"Sleeping in a well-ventilated bedroom benefits your cognitive abilities."

He went on: "An open window is recommended when air pollution is low and if there is no ventilation system in the home. Otherwise, the best solution is mechanical ventilation."
