INDIANAPOLIS – With snow predicted to fall across large portions of Indiana this weekend, the American Heart Association (AMA) encourages Hoosiers to protect their hearts while shoveling snow and to seek immediate treatment if they experience any signs or symptoms of a heart attack.
Research shows that many people may face an increased risk of a heart attack or sudden cardiac arrest after shoveling heavy snow.
“Shoveling snow can be a very vigorous activity, and you’re basically doing it in a freezer,” says cardiologist Dr. William Gill, president of the AMA Board of Directors in Indianapolis. “After only two minutes of snow shoveling, participants in a study had heart rates exceeding 85% of maximal heart rate, a level more commonly expected during intense aerobic exercise testing. The impact is hardest on those who are least fit.”
To help make snow removal safer, the American Heart Association offers these tips:
- Take frequent rest breaks during shoveling so you don’t overstress your heart. Pay attention to how your body feels during those breaks.
- Do not eat a large meal before or after shoveling. It can put an extra load on your heart.
- It is safer to lift smaller amounts more times than to lug a few huge shovelfuls of snow. The act of lifting heavy snow can raise blood pressure acutely. When possible, push the snow.
- Learn the heart attack warning signs. Even if you’re not sure it’s a heart attack, seek help. Fast action can save lives. Don’t wait more than five minutes to call 9-1-1
- Don’t drink alcoholic beverages before or immediately after shoveling. Alcohol may increase a person’s sensation of warmth and may cause them to underestimate the extra strain their body is under in the cold.
- If you have a medical condition, don’t exercise on a regular basis, or are middle-aged or older, meet with your doctor before the anticipated snowfall.
- To prevent hypothermia, dress in layers of warm clothing, which traps air between layers forming a protective insulation. Wear a hat because much of your body’s heat can be lost through your head.
