Mould, asthma and allergies: what you need to know
Can mould set off asthma and allergies?
Yes. Mould is a well-recognised indoor trigger. It releases tiny spores and fragments into the air, and in people with asthma or allergies, breathing them in can irritate the nose, eyes and airways. Typical reactions include sneezing, a blocked or runny nose, itchy or watering eyes and a cough. People with asthma may find their usual symptoms, such as a tight chest or wheeze, harder to keep under control. Mould is only one of many triggers, and plenty of people live with damp walls and never react, but for those who are sensitive it is worth taking out of the home.
Patterns that point to the house
A single sneeze tells you nothing. A pattern tells you more. Symptoms that are worse after a night in one particular bedroom, that flare when you open a certain wardrobe, or that fade on holiday and return when you get home all suggest something indoors. A short diary of when and where symptoms happen gives your doctor something real to work with, especially alongside a note of any visible mould or a musty smell that won't shift.
Diagnosing and treating asthma or allergies is your doctor's job, not ours. If symptoms are new, changing or getting harder to manage, see your GP, and keep following the treatment plan you've been given. If someone is struggling to breathe, call 112.
Where the trigger tends to hide
The patch you can see is often not the whole story. In Cyprus homes, these are the places worth checking:
- Split air-conditioning units, which run hard all summer and can build up damp and grime inside; see mould around air-conditioning units.
- Wardrobes and drawers on outside walls, where clothes and spare bedding pick up spots and smell.
- Behind the headboard and under the bed, where air barely moves.
- Window seals and frames that run with condensation on winter mornings.
- Rugs and carpets laid on cold ground-floor tiles.
- Bathroom ceilings and silicone, if the extractor is weak or missing.
Reducing the trigger at home
Start with the bedroom, because that's where most people spend the longest stretch in one room; our guide to mould in the bedroom covers the common causes. Then work on moisture across the house. Open windows wide for a few minutes each day, even in winter, run extractors while showering and cooking, and dry washing outdoors where you can. In a home that stays damp, a dehumidifier can help, though a dehumidifier won't stop mould on its own if there's a leak or a cold wall behind it.
If you're the one who reacts, ask someone else to do the cleaning, and stay out of the room until it has aired. Whoever does it should wear gloves and a mask, wipe with a damp cloth and a mould cleaner rather than brushing dry, and never mix products. Strong-smelling sprays and air fresheners only cover the odour, and some people find scented products irritating in their own right.
When the source isn't obvious
Sometimes symptoms point clearly to the home, but there's no mould in sight. That usually means moisture somewhere you aren't looking: inside a wall, under a floor or behind fitted units. A room-by-room damp survey to track down the hidden source takes moisture readings in every affected room and ends with a moisture map sent to your phone, plus a written report with the quote. The report usually points to fixes such as a better extractor, insulation for the cold spot or an anti-mould finish. For households who want to keep the air steady afterwards, monthly visits that keep humidity in check catch regrowth early, from €45 a month.
