“House burping” is the latest thing cluttering people’s feeds: short clips of people flinging open every window and door, announcing they’re “burping” their home to get rid of stale, germ-filled air. Behind the playful name is a serious question: does this actually make a home healthier, or are people just swapping indoor germs for outdoor pollution?
In Germany, this trend looks less like a revolution and more like everyday life. Lüften – literally “airing out” – and Stoßlüften, or “shock ventilation”, have long involved opening windows wide for a few minutes to let fresh air race through, even in the depths of winter. Some German rental contracts even mention regular airing as part of looking after the property, mainly to prevent damp and mould.
