Living in houses that are damp and have visible mould can increase the risk of wheezing in some people. If you are allergic to mould, consider:
- Removing visible mould by cleaning with bleach or other mould reduction cleaners
- Ensuring adequate natural ventilation
- Removing indoor pot plants (which promote mould growth)
- Not working with garden compost or mulch
The effects of these measures on asthma control have yet to be tested. Although humidity promotes mould growth, dehumidifiers have been studied and have not been shown to be helpful in asthma control.
