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?


Spain, in winter at least 15 minutes in the morning after waking up and 15 minutes in the evening. In Summer I try not to open the windows during the day only at night because I will be naked alive otherwise
Better than being naked dead I guess.
