“Heart Attack Snow”: Why Shoveling Can Be Dangerous

When winter storms hit like they did this past weekend, many people grab a shovel to clear their driveways and sidewalks. But did you know that heavy, wet snow is sometimes called “heart attack snow”? 

That’s because shoveling heavy snow can put a lot of stress on your heart. 

Dr. Abraham Thomas, an internal medicine specialist with Silver Cross Medical Group in Mokena, explains, “Shoveling snow is like doing intense exercise in freezing weather. If you’re not used to it, your heart has to work much harder, and that can lead to serious problems.” 

Here’s why it happens: Cold air makes your blood vessels tighten, which raises blood pressure. 

At the same time, lifting heavy snow quickly increases your heart rate. For people who have heart disease—or don’t know they have it—this can trigger a heart attack. 

How to Stay Safe While Shoveling Snow

• Warm up first. Do a few stretches or walk in place for a couple of minutes before you start.
• Dress in layers. Keep warm, but don’t overheat. Wear gloves and a hat.
• Take it slow. Shovel small amounts at a time. Don’t rush.
• Push, don’t lift. Whenever possible, push the snow instead of lifting it.
• If you have a snowblower, use it. But even then, take frequent breaks as snow-blowing can also be stressful on the heart when snow is heavy and wet.
• Listen to your body. If you feel chest pain, shortness of breath, or dizziness, stop right away and call 911. 

 “If you have heart problems or risk factors like high blood pressure, diabetes, or smoking, ask someone else to shovel or use a snow blower, but even with a snowblower, take frequent breaks,” Dr. Thomas adds.

Other tips: Stay hydrated, avoid alcohol before shoveling, and try to clear snow early before it gets packed down and heavier. 

With more snow expected in our area next week, remember to play it safe when it comes to your heart.
