What is thunderstorm asthma?
During grass pollen season people may notice an increase in asthma and hay fever. Grass pollen season (October through to December) also brings the chance of thunderstorm asthma.
Thunderstorm asthma is thought to be triggered by a unique combination of high amounts of grass pollen in the air and a certain type of thunderstorm. For people who have asthma or hay fever this can trigger severe asthma symptoms.
When a large number of people develop asthma symptoms over a short period of time, related to high grass pollen and a certain type of thunderstorm, it is known as epidemic thunderstorm asthma. To learn more, visit the Epidemic thunderstorm asthma fact sheet.
If you have current, past or undiagnosed asthma or seasonal hay fever you are at increased risk of thunderstorm asthma. So be prepared to manage any symptoms and stay out of hospital.
