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?


At least once a day. Really depends on the temperature, though. On hot days I open it in the morning to let cool air in, on cold days I avoid leaving it open and only open it temporarily when the air gets noticeably stale, leaving the room when I do so. Inbetween I usually leave it open the entire day.
Though, I only open it fully in the mornings of hot days. Other times I always leave it tilted only.
