You often read that proper ventilation means opening all windows at least three times a day, doing shock ventilation for ten minutes, etc., to remove moisture. However, in our house (timber frame construction, everything dry, and windows with trickle vents), we have a hygrometer in every room showing humidity levels between 40 and 50 percent.

In my opinion, this means I can skip the forced ventilation several times a day, right? It should be enough to ventilate once in the morning after sleeping and after showering, or whenever there’s a smell from cooking, correct?

Yes, this is generally the case if you don’t have a mechanical ventilation system... very few people ventilate properly and regularly. Often there are still items on the windowsills, so you might tilt the window briefly, but not for too long, because of the draft.

Humidity is just one factor; another important aspect is CO2 and the quality of the breathing air. I used to have headaches quite often in the house, but almost never with the ventilation system. Our ppm level is always around 500 to 700.
