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?


Southern US, windows are only open in winter, basically whenever it’s comfortable outside. Never in the summer. The A/C runs basically 24hrs a day during the hottest 2 months of the year.
Windows on the car are basically left cracked for the opposite time. Rain deflector are installed to allow for this without rain getting in.
