The NHS has issued a health alert to 7.2 million people across the United Kingdom, warning that thunderstorms could pose a 'triple threat' to individuals with respiratory conditions. As the British heatwave transitions into wet and rainy weather, with potential thunder in some regions, millions have been advised to take precautions.
NHS Warning on Social Media
In a post on Instagram, the NHS stated: 'Thunderstorms can trigger symptoms for those with lung conditions, like asthma. If the weather makes your symptoms worse and you need to use your inhaler more, talk to your pharmacist, contact your GP or NHS 111.' The accompanying image urged individuals prescribed an inhaler to keep it with them 'during periods of thundery weather.' Inhalers are essential for managing conditions such as asthma and COPD.
Asthma is widespread in the UK. According to Asthma and Lung UK, approximately 7.2 million people have some degree of asthma, equating to about eight in every 100 individuals.
Why Thunderstorms Pose a Risk
People with asthma need to be particularly cautious during thunderstorms because these weather events can trigger sudden, severe asthma attacks, a phenomenon known as 'thunderstorm asthma.' Asthma and Lung UK explains: 'Thunderstorms can trigger your asthma, causing asthma attacks and making symptoms like breathlessness, wheezing, and coughing worse.' The exact reasons for this remain unclear to scientists.
Individuals are more susceptible if they have both asthma and hay fever, are not managing their asthma effectively, or have undiagnosed asthma. Asthma UK also notes that younger adults under 30 are more affected by thunderstorm asthma.
The Science Behind Thunderstorm Asthma
Thunderstorm asthma occurs when high winds draw elevated levels of pollen and pollution particles into the atmosphere. When pollen contacts rainwater, it breaks down into smaller particles. Inhaled deeply into the airways, these particles can trigger asthma symptoms. Combined with pollen and air pollution, this creates a 'triple threat situation' for those with asthma.
Managing Thunderstorm Asthma
Asthma and Lung UK advises staying indoors before, during, and after thunderstorms, and keeping windows closed. Individuals should carry a reliever inhaler at all times for quick use in emergencies. If going outside is unavoidable, wearing a mask can help protect against pollen grains.
