It might be a little chilly, but opening your window at night could help you get a better night’s sleep, so says new research. This is because it allows for a better CO2 balance in the bedroom which, in turn, leads to better sleep quality. And we all know that a good night’s sleep has a drastic effect on our mood and motivation the following day.
The study, published in the journal Indoor Air, tracked the sleeping patterns of 17 students. To do so, scientists used motion sensors to monitor movement, measured CO2 levels and asked participants to keep a sleep diary.
The results revealed that those who slept with the window open enjoyed a better quality night’s kip and didn’t toss and turn so much.
The scientists found that, when the door was closed, the average CO2 level was 1,150 parts per million, but with the window open, the average became a much lower 717 parts per million – a better balance. The scientists believe this is because allowing air to circulate prevents a build-up of CO2 which is caused by respiration and poor quality ventilation.
“Lower CO2 levels implied better sleep depth, sleep efficiency, and a lesser number of awakenings,” the authors said.
So, next time you’re struggling to drift off, throw open the window and breath in some crisp winter air – even if you have to add a blanket on top.
