Heart Health
What kind of weather prompts the most heart attacksWinter storms! A 2004 study found that 53 percent more heart attacks occurred in the winter, with the highest number occurring in January. During cold weather, the heart can be strained by constricting blood vessels, and added exertion from shoveling snow and ice can stress weak hearts. While summer’s heat can also strain hearts, winter heart attacks are generally more serious and more damaging.
Viewer Tip: The weight of snow can vary greatly, from seven pounds per square foot for light, fluffy snow, up to 20 pounds or more for drifted or compacted snow. If you clear snow from your driveway or sidewalks, dress warmly and take it slow. Stretch for a few minutes before you go outside to avoid muscle injury, and stop working if you feel tired or weak. Individuals with heart disease or high blood pressure should seek a doctor’s advice about shoveling snow or performing other strenuous tasks in cold weather.
