Ventilation is necessary to create a healthy living environment. In damp rooms like the bathroom, good ventilation is extra important. This prevents health problems, but also problems such as strange odours, slipperiness, condensation and moisture problems including mould. Mould mainly grows in damp places and is not always visible. You can get rid of mould with baking soda, bleach or more persistent anti-fungal sprays, but this is only a short-term solution. To prevent mould and tackle it at its cause, it is necessary to ventilate the bathroom all year round. Moist air should especially not linger too long, especially if you like to take nice long showers.
