Following a substantial snow and ice event over the weekend, health officials in Pennsylvania have confirmed three deaths tied to snow-removal efforts, all involving individuals aged between 60 and 84 years. The Lehigh County coroner's office has issued advisories urging residents to pace themselves and avoid intense physical exertion while clearing snow.
Snow shoveling constitutes a physically demanding task. Scientific studies indicate that even brief periods of this activity can elevate the heart's workload to levels comparable to vigorous exercise. This strain is exacerbated by exposure to cold temperatures, which cause vasoconstriction—the narrowing of blood vessels including those supplying the heart muscle. The consequent rise in blood pressure increases the likelihood of serious cardiovascular events such as heart attacks, strokes, and cardiac arrests, as explained by the American Heart Association.
Individuals with known heart disease, a history of myocardial infarction, older adults, and those with risk factors like hypertension or elevated cholesterol face heightened dangers related to snow removal. The risk is also present for seemingly healthy people, particularly when combining strenuous exertion with cold weather, especially if they lead a sedentary lifestyle and suddenly engage in physical labor due to a snowstorm.
The American Heart Association recommends a cautious approach for those who must shovel snow. Slowing the pace and favoring pushing the snow over lifting and tossing it can reduce cardiac stress. Additionally, it is imperative to recognize symptoms indicative of a heart attack and seek emergency medical attention immediately by calling 911 if such signs occur.
