Heart Attack Risk Soars as Nation Shovels Out from Snowstorm
As millions of Americans struggle to dig out from the latest winter storm, health officials are sounding a stark warning: shoveling snow can be deadly. The American Heart Association has long listed snow shoveling as one of the top physical activities that put stress on the heart, particularly for those with pre-existing conditions.
According to Dr. Christopher Kramer, a cardiologist at the University of Virginia Health System and president of the American College of Cardiology, the risk of heart attack from shoveling snow is especially high for men and those with multiple cardiac risk factors, including diabetes, high blood pressure, and family history of heart disease.
The reason why shoveling snow can be particularly hazardous lies in the way it combines physical exertion with environmental stressors like cold temperatures. When you push or lift snow, your heart rate and blood pressure increase significantly โ even more so than activities considered strenuous, such as running. And when you factor in exposure to low temperatures, which cause blood vessels to constrict and blood pressure to spike, the risk of cardiac strain becomes even greater.
"The dual problem is that you're increasing demand for oxygen because of the workload, and at the same time, you're reducing supply because of the constriction of the blood vessels in the cold," Kramer explained. "So, if someone who's not in shape and has a lot of risk factors for heart disease goes out to shovel snow on a very cold day, they're essentially putting themselves at risk."
In fact, a 2020 report by the American Heart Association listed shoveling snow as one of the top physical activities that can put stress on the heart. And recent studies have confirmed that even without pre-existing conditions, shoveling snow can increase the risk of cardiac-related hospitalizations and death.
Three people in Pennsylvania's Lehigh County died while shoveling snow during this latest storm, with their deaths ruled as natural and consistent with cardiac events caused by strenuous activity like snow removal. Meanwhile, cardiologist Josh Buckler emphasized the importance of staying safe when it comes to temperature drops, physical exertion, and heart health.
"It's a 2-degree drop that can increase the risk of heart attack," Buckler said. "And that risk lasts for about 28 days afterwards."
So what can you do to lower your risk? Dr. Kramer recommends taking breaks while shoveling snow or, better yet, hiring someone else to do it. If you have cardiac risk factors, he says, "Pay the kid down the street to shovel your walk. Don't do it."
