Risk of potentially deadly 'thunderstorm asthma' increases ahead of wet spring

Doctors are warning wetter conditions in spring could lead to a higher risk of 'thunderstorm asthma', which could pose a danger to Australians with and without asthma.

Much of eastern Australia - including Sydney and Melbourne - is expected to receive above-average rainfall between September and December, meaning grass pollens and other allergens could be transported from rural areas into urban areas.

In certain thunderstorm conditions, these particles can be broken up and enter the lungs, causing an asthma attack even in people who do not regularly suffer from asthma.

One serious incident occurred in Victoria in 2016, when 10 people died after ambulance and emergency services were overwhelmed with the number of people suffering from asthma symptoms after a thunderstorm.

Health experts say all Australians need to be aware of the risks thunderstorm asthma poses.

"Events like thunderstorm asthma can affect people who have never experienced asthma symptoms before," Dr Tony MacDermott said.

"These individuals are less likely to have medication on hand, so it helps to know what medical resources are available to you before an incident strikes, to keep you safe and potentially out of hospital."

People who are allergic to grass pollen and hayfever sufferers are at higher risk of suffering from thunderstorm asthma.

MacDermott urged Australians with these conditions or who suffer from asthma to be vigilant and proactive in looking after their health this spring.

"[We] see increased levels of distress amongst asthmatics during spring which highlights the fact that having a proactive conversation with your doctor can be the best medicine when it comes to seasonal health issues," he said.

"When it comes to asthma or any chronic health condition, the most important thing to have is a plan and the support you need to mitigate any risks and get the right care at the right time."
