Edit: Context behind this question is because my parents always tell me to shut the windows all the way and I kinda feel like I’m suffocating… literally… (it’s Winter here)
Like I just struggle to breathe with windows closed…
So I’m just curious, how do y’all not suffocate while trying to keep house warm and spend less on heating?


Daily, all year roun,for a short time.
Let me introduce you to Stoßlüften.
As a foreigner living in Germany, I just knew this would be the main response. Germans LOVE to air out rooms
Oh… no wonder why my circadian rhythm is fucked up… I feel so tired in the day and now its 1AM and I’m wide awake… 🫠
Lpt: if your residence has central heating/ac and was made within the last 50 years then your house is probably getting sufficient airflow.
Central heating, no AC.
Heat is not carried by air, but by those pipes with hot water running to radiators… so I don’t know if there’s any airflow.
Built before 1978, might have lead paint under there… but it was painted over once before we moved in so its probably lead safe(? I hope lol, i’d be lame to lose a few iq points to something stupid like lead)
Ah, then no forced air through ventilation ducts to move air around.
My current house doesn’t have vents either, but I have fans that move air around the important bits that get occupied the most. With my dogs needing to go out, and work, the doors are open enough, and there’s enough leakage to not worry about co2 levels. Except my wife sometimes trips the sensor in the hallway when she takes a long bath while burning multiple candles…
Oh wise German Airbender, what do I do if I live in a small apartment with no windows across from each other to create a cross draft? My windows in are in two rooms on the same side of the apartment. Save me from ventilation sin!
For real tho if you have any ideas I love fresh air and would love to hear them!
Open them both and then the door, would that help?
Fans are fine, actually, we are not the koreans! You might get a stiff neck from the Zug, but no fan death, probably.
Stoßlüften!!
(aside from rooms having ac, those don’t need it)
