Household mould is one of the leading causes of asthma symptoms, along with house dust mites, according to The National Asthma Council.
“High relative humidity is a key ingredient in the growth of mould and also for house dust mites, with levels around 70 per cent being conducive for both – double trouble for people with asthma,” Department of Clinical Immunology and Allergy, Royal North Shore Hospital Associate Professor Sheryl Van Nunen said.
“Mould in homes can trigger symptoms for many people living with asthma and allergies because they create spores which are airborne and can be inhaled.
“House dust mites are one of the most significant triggers for people with asthma and allergies.”
Symptoms for people with asthma may include increased coughing, wheezing, shortness of breath and a greater need for medications.
Home heating will reduce relative humidity, as will dehumidifiers and good ventilation.
Avoid triggers:
- Remove visible mould by cleaning with naturally fermented white vinegar solution (mould is not always visible and some porous surfaces may need to be removed and discarded)
- Use stand-alone air purifiers
- Ensure adequate natural ventilation including the use of extractor fans
- Seal leaks in bathrooms and roofs
- Clear overflowing gutters and blocked under floor vents
- Remove indoor pot plants, which promote mould growth
- Dry or removing wet carpets
- Treat rising damp as soon as detected
- Avoid the use of organic mulches and compost heaps.
