Thunderstorms can trigger asthma—and it’s not just the weather 🌩️
During a storm, pollen gets swept up into the clouds, absorbs moisture, and bursts into tiny particles. These fragments are small enough to travel deep into the lungs, which can trigger sudden asthma symptoms—even in people who usually just have seasonal allergies.
This is called thunderstorm asthma.
If you’re at risk:
• Stay indoors with windows closed during storms
• Avoid outdoor activity right before and during rainfall
• Keep your rescue inhaler nearby
• Stay consistent with your controller medications
Your lungs don’t just react to seasons—they react to storms too.
