Maybe I am just too Canadian for this, but I recently learned about the trend of 'house burping' and I find it so strange, I will regularly have windows open in my house all day (especially when it is hot outside), not just for 5-10 minutes.
ETA: House burping is a apparently growing trend in the US where people open up their house windows for 5-10 minutes a day to circulate inside and outside air to freshen up the house apparently. Based off of the German practice of Lüften.
