There are several types of moulds that live in your environment. Moulds grow indoors and outdoors in warm, dark, moist areas. Moulds reproduce and grow by sending tiny spores into the air. If inhaled, these spores can cause asthma symptoms.

Environmental Control

Once allergies are identified, the next step is to reduce or eliminate contact with the allergens. This is called environmental control. There is sufficient evidence to show that asthma and allergy symptoms can improve over time if recommended environmental changes are made. Many of these changes are made throughout the home. The bedroom is the most important place as this is where people spend 1/3 to 1/2 of their time.

Steps to Take to Control Mould Allergens

In the bathroom – use the exhaust fan or open the window to let the moisture out after showering
. Dry wet surfaces after showering. Clean bathrooms with an anti-mould spray to prevent mould growth or to kill mould, at least once a month.
In the kitchen – use the exhaust fan to let out steam
. Throw away bad food right away. Take out the garbage daily. Empty the water under refrigerators with automatic defrosting systems frequently.
Throw out mouldy items. Make sure water leakages are cleaned up.Control the humidity level (45% and below) with an air conditioner or dehumidifier.
The dryer should emit air through an exhaust fan leading outside the house because the hot air produced in a working dryer increases the humidity in the room and creates an environment conducive to mould growth. If you must use a humidifier, clean it daily to prevent mould growth. Your health care provider may recommend medication, therapy, or other ways to control the environment. Contact with mould can make asthma symptoms worse for some people. To avoid these problems, follow the steps above to reduce or eliminate contact with mould.
