What is Work-Exacerbated Asthma?

Work-Exacerbated Asthma (WEA)

Work-exacerbated asthma occurs when you are exposed to something in your work place that makes your existing asthma worse. How these exposures will affect you depends on how well your existing asthma is controlled and how severe your asthma is. Your asthma symptoms may get worse for a short period of time when you are exposed to something at work, like smoke, dust, chemicals or fumes. Work-exacerbated asthma could occur just once or twice, or could occur up to most days or every day at work.

When would you notice your symptoms?

If you have asthma already, you might notice that your asthma gets worse simply when:


  • you are in the work environment, or
  • in certain areas in the work environment, or
  • when you are doing certain tasks at work.


Your asthma may improve on days off work, especially after 2 or 3 days off, or when you are on holiday, and then may get worse again on some days or every day when you are back at work.
