ALLERGEN AVOIDANCE TIPS

Asthma may be triggered by a wide range of environmental factors.  Whilst complete avoidance of these triggers is impractical, identifying the common ones and taking simple measures to avoid them, can go a long way in helping keep your asthma under control.

Dust Mites:

House dust mite is a universal allergen.  Whilst there is no single most effective method, the following steps, in combination, can help reduce exposure to mite allergens.

• Encase pillows, mattresses etc with allergen-proof, anti-dust mite covers.
• Wash all bedding and stuffed toys in hot water (exceeding 60 degrees Celcius) once a week.
• Avoid carpets, thick curtains and stuffed toys where possible.
• Use vacuum with integral, HEPA filters.
• Keep all clothing in drawers/closets to reduce dust collection.
• Clean all surfaces with a damp cloth regularly.
• Regularly change and clean air conditioner filters.
• Keep clutter under control.

Animal Dander:

Avoid keeping animals that shed fur.  Animal dander is a well known trigger for asthma.  If you already own an animal or are keen on keeping one, keep your pet away from your bedding and bathe your pet regularly.

Air Pollution:

Most studies show an association between air pollutants and asthma exacerbation.  During periods of haze, patients with asthma should avoid strenuous outdoor activities.

Smoking:

Asthmatics should avoid smoking and exposure to second hand smoke.

Insect Control:

Many homes have cockroaches and other insects which may potentially trigger asthma. 

• Use cockroach baits and traps.
• Insecticides may be used, but not in the presence of those who are asthmatic.  Ensure that rooms are adequately aired before entering them.

Occupational Triggers:

The possibility of occupational triggers should be considered in adult onset asthma.  It should also be considered in a known asthmatic if asthma appears to be made worse in relation to work.

The range of occupational sensitizers is very large and complex, and will require assessment by a specialist.

Food And Food Additives:

True food allergies are uncommon, and exhaustive testing for food allergies is usually impractical.
