Locals are being urged to prepare for the risk of thunderstorm asthma events over the next few months, with health authorities warning the condition can strike even people who have never experienced asthma before. The Murrumbidgee Local Health District (MLHD) issues annual spring warnings about thunderstorm asthma events. Although these events are rare, they can occur when specific weather conditions cause rye grass pollen to break apart into tiny particles, which can then be inhaled deep into the lungs, triggering severe breathing difficulties. While people with existing asthma or hay fever are considered most at risk, asthma can also affect those with no history of respiratory problems by causing sudden and severe breathing difficulties. With pollen levels expected to rise in the next few months, regional and rural communities are being encouraged to be aware of the risks and take simple steps now to protect themselves ahead of the thunderstorm season. People with asthma or hay fever are strongly encouraged to consult with their GP or pharmacist, ensure medications are up to date and review their asthma action plan. The warning is especially important for farming communities in the Riverina, where rye grass pollen levels can be higher than expected. Staying indoors during thunderstorms, with windows and doors closed, is considered the best way to reduce exposure to airborne pollen particles. Even people without a diagnosis of asthma or hay fever are being encouraged to remain alert to symptoms during storm events. If you or someone around you is experiencing severe symptoms, please call triple zero (000) immediately.
