Smoke on the Horizon
What Wildfire Smoke Means for Your Heart
If the sky over the Capital Region looks a little yellow this week, you're not imagining it. Smoke from wildfires burning in Canada has drifted south again, and New York State has issued an air quality advisory covering the entire state. We've seen this before, and it's worth talking about, because most people think of wildfire smoke as a lung problem. It's a heart problem too.
Wildfire smoke carries tiny particles, far smaller than a grain of sand, that are small enough to pass from your lungs into your bloodstream. Once there, they can stress the cardiovascular system. On smoky days, hospitals see more visits not just for breathing trouble, but for heart-related symptoms as well. If you're an older adult or you're managing a heart condition, smoky air deserves the same respect you'd give a heat wave.
The encouraging part: protecting yourself is simple, and most of it happens indoors.
Check before you head out. The Air Quality Index, or AQI, is a color-coded score you can find at AirNow.gov or in most weather apps. Green and yellow mean most people are fine. Orange means sensitive groups, including people with heart conditions, should take it easy outdoors. Red or worse means everyone should limit time outside. Conditions can change from morning to afternoon, so check the day you plan to be out, not the day before.
Move your workout inside. Exercise makes you breathe harder and deeper, which means more smoke gets in. On poor air days, trade the outdoor walk for a lap around the mall, a home workout, or a rest day. The trail will still be there next week.
Keep indoor air clean. Close windows and doors, and run your air conditioner if you have one, since it filters and circulates air. A portable air purifier with a HEPA filter can make one room noticeably cleaner, and that's a fine strategy: pick a room, keep it closed up, and spend the smokiest hours there. Skip candles, fireplaces, and frying on bad air days, since they add particles to the air you're trying to protect.
Listen to your body. Scratchy throat and watery eyes are common and usually harmless. But if you notice chest discomfort, unusual shortness of breath, a racing or fluttering heartbeat, or unusual fatigue, don't chalk it up to the haze. Contact your care team, and if symptoms are severe, call 911.
Look out for your neighbors. Smoke events are hardest on older adults, people who live alone, and anyone without air conditioning. A phone call or a spare box fan can go a long way.
Smoke events usually pass within a few days as the weather shifts. Until this one does, take it a little slower, stay inside when the air is at its worst, and keep an eye on that AQI. Your heart will thank you.
