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?


My body runs like an oven when I’m asleep. To that end, I have the heating off by the time I’m in bed (winter), and if the air still isn’t crisp enough, I’ll open the window a crack.
In the warmer months I straight up cannot sleep if the windows are closed.
Edit: forgot to mention that I am in the UK
