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 have sensors that let me know when the outdoor temperature and humidity are both better than indoors so I can open the windows. Typically that’s an hour or two a day in the winter when the weather is nice, and most of the day in the summer.
