The Met Office has warned that thundery conditions during the upcoming heatwave could affect the health of 7.2 million people in the UK who have asthma. The weather forecast indicates that temperatures will rise quickly this week, bringing a chance of thundery showers for some areas. This combination of heat and thunderstorms can trigger severe asthma symptoms, a phenomenon known as 'thunderstorm asthma'. The NHS has previously cautioned that thunderstorms can exacerbate lung conditions like asthma, advising those affected to use their inhaler more frequently, consult a pharmacist, or contact their GP or NHS 111.
Thunderstorm Asthma Risk
According to Asthma and Lung UK, approximately 7.2 million people in the UK have asthma, equating to about 8 in every 100 individuals. Thunderstorm asthma can cause sudden and severe attacks, leading to breathlessness, wheezing, and coughing. While the exact cause is not fully understood, experts believe it is linked to a combination of high pollen levels and atmospheric pollution particles, which are often present during thunderstorms. People with both asthma and hay fever, those not managing their asthma well, and undiagnosed individuals are at higher risk. Younger adults under 30 are particularly susceptible.
Health Advice and Precautions
The NHS recommends that individuals with asthma who are sensitive to thunderstorm conditions should ensure they have their inhaler readily available and follow their asthma action plan. For additional support, Asthma and Lung UK offers a summer wellness guide and a helpline at 0300 222 5800. The charity advises staying indoors during thunderstorms, closing windows, and using air conditioning if possible to reduce exposure to triggers.
Weather Forecast and Heatwave Impact
The Met Office has issued amber and red heat warnings for parts of the UK, with temperatures expected to reach 35°C in some areas, causing schools in England and Wales to close early. London could see highs of 36°C on Wednesday, while parts of the South East may reach 39°C by Thursday. Nearly 100 areas are affected by severe weather warnings. People are urged to stay out of the sun between 11am and 3pm, when UV rays are strongest, and to stay hydrated. The combination of extreme heat and thunderstorms poses additional health risks, particularly for those with respiratory conditions.
