Thunderstorms Spark Asthma Fears

The NHS has issued a warning regarding the dangers of thunderstorms for individuals with specific health conditions, particularly asthma. These storms can cause a sudden and severe worsening of respiratory symptoms due to a phenomenon known as 'thunderstorm asthma.'

This occurs when the high winds and moisture within a storm break down pollen and fungal spores into extremely small particles. These particles are then inhaled deeply into the lungs, triggering inflammation and airway narrowing in susceptible individuals.

While rare, thunderstorm asthma can affect anyone, but those with asthma, undiagnosed asthma, or hay fever are at greater risk. Younger adults, especially those under 30, are also disproportionately affected. People with other respiratory illnesses like COPD may also experience increased hospital admissions.

Health authorities monitor NHS 111 calls and emergency data for surges in breathing problems following storms, with potential episodes noted in recent years. Individuals are advised to stay indoors during thunderstorms, keep windows closed, take prescribed medication, and carry their inhaler.
