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?
Northern Spain here, they remain closed all winter except the few times I open them to ventilate. Next month I’ll probably start opening them during the day and at some point in May or June they’ll remain open until the end of September or so.
