Work-Related Asthma

Welcome to the work-related asthma website!

Asthma is a chronic (long-term) disease that makes it difficult to breathe. It can be active or quiet, and certain triggers may make it suddenly very active. Because many such triggers can be found in workplaces, it is common for people's asthma to get worse at their work.

We are a research group from the University of Toronto and McMaster University and our goal is to help people with asthma to understand what work-related asthma is and to give them information about what they can do to avoid or control it.

What is work-related asthma (WRA)?

When something you breathe in at your workplace causes asthma or makes your existing asthma worse, the condition is referred to as work-related asthma. There are two types of work-related asthma:

  • Occupational Asthma (OA)
  • Work-Exacerbated Asthma (WEA)
