Proper Ventilation and Dehumidification

Is there any reason not to keep one window tilted per floor open from 10 a.m. to 4 p.m. on a sunny and dry (but cool) day? I tried this last week and all the windows (as well as the foil covering the attic hatch) were completely free of moisture condensation by the evening. The heating is also running continuously (screed heating-up phase).

Warm air absorbs more moisture, right? So then keep the windows closed and open them 2-3 times a day for 10 minutes each to create a draft. Permanent tilt is not good, no matter when or how.

Smoking is fine. That's how it is. Dehumidifier works better. That's also how it is.
