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?


I find that I need to open them 2-3 times a day.
I open them when humidity goes above 60% in my room, and keep it open until it reaches under 50.
This usually means opening them 2-3 times daily.
Otherwise I get the same suffocating feeling.
This definitely varies by region.
