Asthma and Airway Centre

AIR CONDITIONING - This will reduce exposure to pollen and fungal spores when used with the windows and outside doors closed. Units which accumulate water should be regularly cleaned to prevent fungal contamination which may worsen symptoms in allergic patients.

AIR PURIFIERS - Despite the sales pitch you might hear, these are not guaranteed to improve symptoms. The most effective air cleaners have a HEPA filter and can reduce exposure to airborne substances causing allergic reactions. However, the most common cause of indoor allergic responses, the dust mite, is found in carpeting and mattresses and is not removed by air cleaners. The amount of airborne mite allergen can be reduced to some extent. HEPA filter air cleaners are expensive and relatively large. It is best to rent or borrow initially to see if it will help you.

BEDROOM AND BEDDING - Mattresses, box springs and pillows should be encased in synthetic dustmite proof covers to limit exposure to dust mite if this is a trigger for you. Pillows and comforters stuffed with feathers may trigger an asthma attack. Synthetic materials such as Dacron or polyester are recommended. Use blankets that can be washed easily in a washing machine and that are made from cotton or synthetic fibre (e.g. acrylic, dacron or polyester). Woolen blankets should be avoided. Remove unnecessary dust collectors such as toys, bookshelves and ornaments. Hang clothes in closets.

FURNISHINGS - Stuffed furniture and heavy drapes may be a source of dust or other allergens. Furniture stuffed with foam and light clean drapes are recommended. Carpets, especially in the bedroom, are not advised. If present, they should be cleaned regularly. Use a damp cloth or mop when dusting. This collects the dust rather than scattering it.

HUMIDIFICATION - Excess humidity encourages the growth of dust mites and fungi. We recommend that you keep the humidity in the house below 50%. You can use a hygrometer (available in most hardware stores) to monitor the humidity level. Dehumidifiers may be needed, especially in summer, but if used should be cleaned frequently to prevent fungal contamination.

PETS - Cats, dogs, birds or other furry animals can be a constant asthma trigger for many asthmatics and it is best to remove them from the home. If not possible, practice some preventive measures such as keeping them outdoors as much as possible and out of the bed and bedrooms. Cats should be washed at least once a week and cared for by another member of the family. Remember that keeping a pet someone is allergic to may result in that person requiring more medication to relieve symptoms and to keep his or her asthma under control.

SMOKING - Smoking remains a major preventable cause of lung disease. You should never smoke and your family and friends should not smoke in your presence. Ask your doctor about smoking cessation programs and helpful new medications, or phone the Lung Association.

TOYS - Washable toys are recommended. Stuffed toys should be filled with synthetic fibre or polyester for easy care. Wash in hot water to kill dust mites. (Stuffed toys may also be placed in a freezer bag and put in refrigerator overnight to kill dust mites).
