Hot showers fill bathrooms with steam. If that warm, moist air has nowhere to go, it sits on walls, ceilings, tiles and grout. Over time, this constant dampness encourages mould and mildew, especially in corners and on ceilings.
If you open a window, turn on an exhaust fan, or at least leave the door open after bathing, you let the steam escape and the room dry faster. The less time surfaces stay wet, the less chance mould has to grab on.
It’s a tiny habit that keeps your bathroom from turning into a science experiment on the ceiling.
