How do moulds and fungi affect asthma?
Normally, when people breathe in these spores, their immune system helps get rid of them by coughing or sneezing them out, or their eyes might water to wash the spores away. If you aren’t sensitive to mould, you may never even experience a reaction. But for some people with asthma who are sensitive to mould spores, it can act as a trigger, causing asthma symptoms to get worse.
Spore numbers increase when there’s a sudden rise in temperature in a moist environment, such as when central heating is turned on in a damp house, when wet clothes are dried next to a radiator or when the sun comes out after it’s been raining on a warm day
