A study of 40 people indicates that fresh air helps people get a good night’s sleep.
The first week the subjects slept normally and the second week they were asked to open the window.
Sleep trackers showed study subjects slept better when windows were left open.
“Bedroom air quality can affect your cognitive abilities, such as your ability to concentrate, understand and interact,” said Dr Pawel Warjoki, lead author of the study from the Technical University of Denmark. “Sleeping in a well-ventilated room benefits your cognitive abilities.”
The people in the study reported that they were less sleepy in the morning and evening and slept more soundly.
A much larger study is needed to confirm the findings of the new research, but the findings come after an earlier small study involving members of the same research team suggested that opening a bedroom window reduced the snoring.
