"Snowy Heartaches: How Shoveling Can Spark Cardiac Chaos"
As the winter months set in, many of us find ourselves facing off against the deep, heavy snow that seems to blanket our cities and towns. But beneath the seemingly innocuous act of shoveling snow lies a sinister reality: this simple task can be a recipe for heart attack, especially for those who are already at risk.
A study published in 2011 found that nearly 200,000 U.S. residents were treated in emergency departments for snow-shovel related injuries between 1990 and 2006, with cardiac-related deaths adding up to 1,650 during the same period. In Canada, research has shown that men who shovel more than seven inches of snow are at a 16% higher risk of being hospitalized for heart attacks, while those who die from these events have a 34% increased risk.
So what's behind this alarming trend? According to Dr. Benjamin Rosenfeld, a cardiologist at Jefferson Einstein Montgomery Hospital, it all comes down to the intensity and physical strain that shoveling snow imposes on the body.
"For people who are typically sedentary or minimally active in their normal daily lives, they may be prompted to go out and shovel snow – which is a substantially more intense physical task than what they would normally encounter," Dr. Rosenfeld explains. "And so it may just be the intensity that then could unmask some cardiac disease that has been brewing prior to that."
Another key factor in this phenomenon is the cold, dry air that can cause vasoconstriction – a tightening of the blood vessels. This puts more strain on the cardiovascular system and lungs for people with pre-existing heart or lung disease.
But even healthy, fit individuals are not immune to the risks of shoveling snow. Dr. Rosenfeld notes that shoveling is a defined task that requires a certain level of mental toughness – a sense of "I won't stop until I finish" that can lead even healthy people to overexert themselves and push their bodies beyond what's safe.
"You feel, at least mentally, like you're not going to stop until you finish shoveling the snow," Dr. Rosenfeld says. "They may exceed what is really safe or comfortable for their body – regardless of whether they have any health condition in the first place."
Of course, this doesn't mean that healthy individuals are off the hook. Even those who exercise regularly and maintain a healthy weight and blood pressure can be at risk if they're not prepared for the physical demands of shoveling snow.
So what advice would Dr. Rosenfeld offer to those heading out into the snowy fray? For patients with pre-existing heart or lung disease, he recommends hiring someone else to do the heavy lifting – or having a younger family member who's healthy and fit help you out.
"My biggest advice, too, is that you shouldn't ignore symptoms," Dr. Rosenfeld cautions. "Sometimes things happen completely out of the blue. But usually there are some warning signs, and people have a habit of either ignoring it or thinking, 'Oh, it's just my heartburn.' Or, 'I didn't sleep well last night.'"
So listen to your body – if it's telling you that something's wrong, take it seriously and talk to your doctor about it. With caution, common sense, and a bit of holiday cheer, we can all navigate the snowy landscape without putting our hearts at risk.
