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?


As soon as the air feels stale you gotta turn off your heating and open all windows for like 5-10 mins in the cold seasons. Air is bad at carrying heat anyway, if you close your windows it’ll get warm again quickly.
