Thunderstorm asthma
During grass pollen season (1 October through to the end of December) people may notice an increase in asthma and hay fever. It 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.
