Warning issued as thunderstorms could trigger severe asthma symptoms

The Asthma Society of Ireland is urging people with asthma and hay fever to take precautions as thunderstorms become possible following the period of exceptionally hot weather.

The Asthma Society is warning people to take extra care, as thunderstorms during peak pollen season can trigger sudden and severe asthma symptoms.

They say that Ireland has some of the highest rates of asthma in the world, with over 450,000 people in the country having asthma. On top of this, 80% of people with asthma also have hay fever, making people much more vulnerable during these periods.

CEO of the Asthma Society of Ireland, Eilís Ní Chaithnía, said: “While many people welcome the recent warm weather, thunderstorms during pollen season can pose a risk for people with asthma and hay fever. Strong winds can break up pollen grains into tiny particles that are easily inhaled deep into the lungs, triggering sudden asthma symptoms. For some people with hay fever, this may even be the first time they experience asthma.

“We want people to be aware of the risks, take simple precautions and continue following their asthma management plan so they can enjoy the summer safely.”

During these storms, winds can carry pollen grains close to ground level, where they absorb moisture and break into smaller particles that are easily inhaled into the lungs. This is commonly known as “thunderstorm asthma”.

The Asthma Society are encouraging people to follow these steps:

Eilís Ní Chaithnía concluded: “Symptoms of an asthma attack can include coughing, wheezing, chest tightness, struggling to breathe or speak, or lips turning blue. An asthma attack is an emergency and requires immediate action. The person should sit upright and take their reliever inhaler. If symptoms persist or worsen, call 112 or 999 immediately.”
