To not understand how people sleep with the window shut?

Friend has just text to say her and dp have ha a massive row as he wants the window open and she doesn't as she's scared bugs or spiders will get into her mouth
.

I always sleep with mine open, even in winter and I took her DPs side and now I'm in the dog house too

If you sleep with your windows closed, how do you manage to sleep with no air con and no fan either?!

I never have the heating on for more than an hour a day, and never at night, so an open window wouldn't make that much difference.
