Mould and Asthma: The Hidden Trigger in Adelaide Homes

If your asthma has been worse this winter — more puffer use, more night-time symptoms, more GP visits — your home might be the trigger. Indoor mould is one of the most significant but overlooked asthma triggers in Australian homes.

How Mould Triggers Asthma

Mould spores are tiny enough to penetrate deep into your lungs. For people with asthma, inhaling these spores triggers inflammation in the airways, causing bronchospasm, mucus production, and the classic symptoms of an asthma attack. Repeated exposure leads to chronic airway inflammation — making attacks more frequent and harder to control.

Adelaide’s Asthma-Mould Connection

Adelaide’s winter conditions — cold walls creating condensation, homes sealed against the cold, reduced ventilation — spike indoor mould levels exactly when people spend the most time indoors. Bathroom mould, bedroom wall mould, and hidden mould in roof cavities all contribute to high spore counts. Read about all mould health effects.

What Doctors Recommend

The Australasian Society of Clinical Immunology and Allergy (ASCIA) recommends mould remediation as a key step in asthma management for sensitised individuals. This means: identify the mould, remove it professionally, and fix the underlying moisture problem. A mould inspection is the starting point. View typical remediation costs.
