Wildfires: how to protect your lungs from harmful smoke

Summary

Wildfire smoke, containing hazardous pollutants like PM2.5 and NO2, can travel hundreds of kilometers, impacting air quality and health. Protecting yourself involves staying indoors with windows shut, using air purifiers, and wearing N95 or similar masks when outdoors.

Key Takeaways

1. Wildfires have broken out in France, Germany, Greece, Spain and Portugal this summer, and most countries in western and central Europe are currently experiencing extreme fire danger conditions.
2. Wildfire smoke is a mixture of hazardous air pollutants, such PM2.5, NO2, ozone, aromatic hydrocarbons and lead.
3. When wildfire smoke reaches unhealthy levels, stay indoors as much as possible, with doors and windows shut to keep the wildfire smoke out.
