Shoveling snow can be dangerous. Here's how to protect yourself

Shoveling snow presents a significant cardiovascular risk, often pushing individuals to 97% of their maximal predicted heart rate within just ten minutes of exertion. Dr. John Osborne, a cardiologist with the American Heart Association, explains that moving heavy, wet snow relies heavily on upper extremity strength rather than larger leg muscles, placing immense strain on the heart. Cold temperatures exacerbate this danger by causing vasoconstriction, which increases blood pressure and heart rate simultaneously. Individuals over age 45 or those with pre-existing conditions like diabetes, high blood pressure, or a history of heart surgery should exercise extreme caution or seek assistance. Safety strategies include dressing in layers to manage body heat, taking frequent breaks to catch one's breath, and recognizing that even recreational activities like trekking through deep snow for sledding can be as physically demanding as a formal stress test.
