Heart Attacks Surge: The Hidden Dangers of Shoveling Snow
27 Jan
Summary
- Shoveling snow is linked to increased heart attack and cardiac death risk.
- Cold weather constricts blood vessels, increasing strain on the heart.
- Three individuals died from suspected cardiac events while shoveling snow.
Shoveling snow, a common winter chore, is increasingly recognized as a serious risk factor for heart attacks and sudden cardiac death. Cardiologists emphasize that the physical exertion involved, coupled with exposure to cold temperatures, places an immense strain on the cardiovascular system. This strain is amplified as cold weather causes blood vessels to constrict, raising blood pressure and exacerbating the heart's workload.
Experts explain that this creates a dangerous scenario: increased demand for oxygen due to physical activity and reduced supply from constricted vessels. This is particularly perilous for individuals with known cardiac risk factors such as diabetes, high blood pressure, or a sedentary lifestyle. Recent incidents underscore these dangers, with three older adults in Pennsylvania succumbing to apparent cardiac events while clearing snow during the latest winter storm.
Further research indicates a correlation between heavy snowfall and increased cardiac hospitalizations and deaths, particularly in men. To mitigate these risks, health officials strongly advise individuals with cardiac risk factors to avoid snow shoveling or, at a minimum, to take frequent breaks. Paying someone else to perform the task is recommended for those at higher risk.
