Imagine a picturesque summer day: clear skies, a gentle breeze, and the promise of outdoor activities. However, for some individuals, this idyllic scene can quickly turn into a health hazard. Thunderstorm asthma, a weather-related trigger of asthma and hay fever, has emerged as a fascinating yet concerning phenomenon that warrants attention. In this article, we will explore the causes, risks, and preventive measures associated with thunderstorm asthma, providing valuable insights for health-conscious readers.


Unravelling the Science Behind Thunderstorm Asthma:

During a thunderstorm, warm air rises, carrying with it pollen and allergens. When this air reaches the dew point and begins forming clouds, scientists believe that the pollen particles break down and combine with water droplets. Subsequently, when it rains, these altered pollen particles become more easily inhaled, potentially triggering asthma attacks and severe hay fever symptoms. The connection between thunderstorms and respiratory distress is a phenomenon that scientists are actively investigating, particularly in relation to weather fluctuations.


Understanding the Risks:

Not everyone is equally susceptible to thunderstorm asthma. Certain factors increase an individual’s vulnerability, including:


  1. Asthma sufferers: People with pre-existing asthma, especially if it is poorly controlled or prone to rapid deterioration, face a higher risk during thunderstorms.
  2. Younger individuals: Those in the under-30 age group tend to experience more pronounced adverse effects.
  3. Hay fever sufferers: Individuals with severe hay fever symptoms should be particularly cautious during thunderstorms.


Protective Measures You Can Take:

Fortunately, there are steps you can take to minimize the impact of thunderstorm asthma. By following these practical suggestions, you can significantly reduce the risk of respiratory distress:


  1. Prioritize asthma prevention: Stay up to date with your asthma checks and ensure you have an adequate supply of inhalers. Take your preventer inhalers regularly and as prescribed. Having an updated asthma plan is crucial.
  2. Consider preventive antihistamines: If you are usually able to take antihistamines, consider taking them before, during, and just after a thunderstorm. Consult with your doctor or pharmacist for appropriate recommendations. You can do this at Greenlight Pharmacy next door, or with a GP consultation with one of our expert GP team
  3. Rinse away allergens: Use a saltwater nasal spray like Sterimar to flush your nose before bedtime. This helps remove pollen allergens and provides relief.
  4. Seek shelter indoors: When thunderstorms are imminent, it is advisable to stay indoors. This reduces exposure to pollen and allergens carried by the storm.
  5. Identify and avoid triggers: Be aware of your personal hay fever and asthma triggers, and take necessary precautions to avoid them.
  6. Utilize technology: Stay informed about pollen counts by using resources such as the Met Office Weather app. Knowing when pollen levels are high can help you prepare and take appropriate preventive measures.



As our understanding of thunderstorm asthma continues to evolve, it is essential for health-conscious individuals to be aware of this unique weather health phenomenon. By staying informed, implementing preventive measures, and seeking guidance from healthcare professionals, you can effectively safeguard yourself against the risks associated with thunderstorm asthma alongside the pollen bomb that has hit the United Kingdom this month.
