Thunderstorm asthma

Thunderstorm asthma can be very serious for people with asthma. The peak time for thunderstorm asthma is mainly spring but can extend to December during the grass pollen season. Your local media may announce ‘Thunderstorm Asthma Alerts’ on days when there is a high risk. 

Thunderstorm asthma events are thought to be triggered by an unusual mix of high levels of grass pollen and a certain type of thunderstorm. During these storms tiny pollen grains from grasses can be swept up in the wind and carried long distances.  When exposed to this air, the tiny particles of pollen are breathed deep into your lungs, triggering an asthma flare-up or attack. 

WHO CAN GET THUNDERSTORM ASTHMA?

You might have a higher chance of a sudden asthma flare-up triggered by a thunderstorm if you have:   

  • seasonal hay fever   
  • current asthma   
  • a history of asthma 
  • undiagnosed asthma.   

The chance of having thunderstorm asthma is highest for adults who are sensitive to grass pollen and have seasonal hay fever (with or without known asthma). The worst outcomes are in people with poorly controlled asthma. 

WHAT CAN I DO?

To lower the chance of having thunderstorm asthma when it is a known trigger for you, it is best to have good asthma management year-round.   

This means:   

  • using your preventer especially during the spring thunderstorm season   
  • keeping your hay fever under control and taking any necessary hay fever medication 
  • checking pollen levels and where possible avoid being outside on these days.  
  • being prepared. Have your scripts and supply of your asthma and hay fever medicines ready for the thunderstorm asthma and pollen seasons.
