Smoke – wood heaters, woodfires and bushfires

Woodfire and bushfire smoke is a type of air pollution and is not good for your health. It can lead to more asthma symptoms and flare-ups. Wood heater, woodfire and bushfire smoke (including hazard burns) contains fine particulate matter (PM2.5). These particles are tiny in size and when inhaled can go deep into your lungs, causing inflammation (redness and swelling). The particles can also enter your bloodstream, which can affect other parts of the body like the heart and immune systems.  



Keep using your preventer as stated in your Asthma Action Plan to help lower your chance or severity of a flare-up. Always carry your reliever puffer with you. 

If you are not prescribed a preventer, see your doctor, or talk to one of our Asthma Educators if you are not sure.
