Mould in the bedroom: causes, health and how to stop it
Quick answer
Bedroom mould is usually caused by overnight condensation — we release a lot of moisture breathing as we sleep, and in a closed room it settles on cold external walls. Improve ventilation, move furniture off cold walls, reduce humidity, and treat affected areas.
Why bedrooms get mould
Bedrooms are closed for hours every night while we breathe out litres of moisture. With the door shut and windows closed, that humid air condenses on the coldest surfaces — typically external walls, corners and behind furniture. It's why bedroom mould so often appears low in a corner or behind the bed.

You spend a third of your life in this room, so it's worth taking seriously — see is it safe to sleep in a room with mould. For anyone with allergies or asthma, bedroom mould can affect sleep and breathing.
Common hotspots
Cold external walls, window reveals, ceiling corners, and behind wardrobes and headboards where air can't circulate. The cause is nearly always condensation from poor ventilation.
How to fix it
Ventilate the room daily, pull furniture a few centimetres off external walls, reduce humidity, and don't dry laundry in there. Treat existing mould with mould treatment; if it's in the plaster or keeps returning, get it inspected. An mould inspection finds the moisture source, and for persistently damp bedrooms a monthly maintenance plan keeps it clear.
