Wow. Didn't realize how important it was to aerate. I seldom open the windows at my place.

I also remember often getting really dizzy working in my previous office, and I couldn't understand why, maybe you're on to something.

Now I'm wondering how all of that has affected my health along the years

The recommendation here in Denmark is to air out for ~10 minutes, 3 times a day, ideally with all doors and windows open, making sure to get good airflow between rooms.

I think very few people actually air out that much, but I've found that it's very helpful for my sleep quality to air out just before I go to bed. Airing out in the morning also helps eliminate moisture from showering, as my bathroom doesn't have a window, nor any forced ventilation.
