If you’ve not got one, I would highly recommend getting an air quality meter.
I had this issue last night, awake randomly at 2-3am. When I checked, the air quality was terrible. (It’s bespoke scale put it at 10 out of 100) after opening a window and letting it improve, I happily drifted back off.
It turned out I didn’t wake up randomly, I was dragged awake from a light sleep due to the air quality plummeting. It won’t apply to everyone, but it’s worth checking if it’s a common problem.
(For reference, 10% air was CO2 of 2360ppm, and VOCs at 5000ppm with 80% humidity. Fresh air is CO2<500, VOCs<100)
Room is too well insulated and sealed. Once the bedroom door is closed, the air exchange is too low. I’m planning to fit a heat exchanging fan system next year to permanently fix it.
Opening a window isn’t as bad as it first seems. Most of the heat in a home (at least a brick one) is in the structure. Change the air, close the window, and it will rapidly warm up again. It’s only leaving it open for longer periods that cool it down.
My bedroom window is open no matter how frigid it might be. It’s fab to have that cool air waft across your face when ever you flip and expose a warm cheek.

Any idea what causes the air quality to change so drastically? The aircon / heater not circulating air? Doors closed and no one going in or out?
Just curious if there are other ways to remedy the situation without opening a window in the (soon to be) middle of winter.

Cool. Understood. Thank you.
