Asthma Facts

What triggers asthma symptoms?

Once someone has asthma, symptoms are set off or made worse by "triggers". These can include:

  • colds and flu
  • cigarette smoke
  • exercise
  • inhaled allergens - e.g. pollens, moulds, animal dander and saliva and house dust mite
  • changes in temperature and weather
  • chemicals and strong smells
  • some foods and food preservatives, flavourings and colourings
  • certain drugs (e.g. aspirin)

However, often we don’t know what triggers an episode of asthma.
It is recommended that wherever possible, known triggers should be avoided. Sometimes these triggers are difficult to avoid such as colds and viruses. Exercise, of course, should not be avoided and there are steps that can be taken to help prevent symptoms occurring when exercising. Check out our brochures or contact The Asthma Foundation of WA for more information.

Avoiding Triggers

It is important to try to avoid the triggers that you react to. Sometimes these triggers cannot be avoided e.g. a change in the season or getting a cold. You should ask your doctor for a plan to tell you what to do in these situations. Exercise, of course, should not be avoided. The Asthma Foundation of WA have a range of brochures and Fact Sheets which deal specifically with certain triggers and how best to avoid them. Check out our brochures or contact the Asthma Foundation of WA for more information.

Exercising or being active

Exercise is very important for your health and for developing strong breathing muscles. If you are fit and healthy you will cope better if you have an asthma attack. If exercise triggers your asthma ask your doctor how to control this. Contact the Asthma Foundation of WA to find out about the benefits of exercise and how to control your asthma when exercising.
