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 always have a window cracked open in my room, but SoCal coastal weather is best in the world year round. There are few locations with deep water upwelling AND onshore flow atmospheric patterns. Of those, there is only one other location, in Peru, where it is also a temperate desert.
My weather is the same but I live on the first floor on a very busy Los Angeles street, so opening the windows lets in too much unfiltered grit and smog. I do step out onto the balcony daily to care for my plants and feed the birds, so some air gets in then.
