Dust Storms and Your Health: What to Do When the Wind Picks Up

Dry soil, construction sites, unpaved roads, and drought-stressed land all feed dust storms. When wind speeds jump, coarse PM10 surges first — and fine PM2.5 often follows as smaller particles stay airborne.

How wind raises particulate matter

PM10 includes grit that irritates eyes, nose, and throat. PM2.5 from dust can penetrate deeper into the lungs. AQI may jump quickly even without factory smoke or traffic, especially in arid interiors and during spring frontal winds.

Protect yourself

1. Check AQI and wind forecasts — postpone yard work and outdoor sport when dust is high.
2. Wear wraparound glasses and a well-fitted N95/KN95 mask if you must be outside.
3. Keep car windows closed and recirculate air in dusty traffic.
4. Rinse exposed skin and change clothes after being outdoors.
5. Use a HEPA purifier indoors if dust infiltrates your home.
