Winter Pollution Headaches: Triggers & Prevention

• Winter often brings "smog headaches" caused by microscopic pollutants (PM2.5) leading to neuroinflammation and oxidative stress in the brain, exacerbated by cold-induced vasoconstriction.
• Common winter triggers include morning walks in smog, car heaters, dehydration, and indoor pollutants from cooking, incense, and dust in closed homes.
• Prevention involves checking AQI, avoiding outdoor activities during high pollution, staying hydrated, consuming antioxidants, ensuring ventilation, and wearing an N95 mask outdoors.
• Consult a neurologist if headaches are severe, persistent, or accompanied by vomiting, blurred vision, or slurred speech.
