What makes shoveling snow uniquely dangerous has to do with the activity itself, which is why the American Heart Association has been working to raise awareness of the unique risks involved. Here’s why:
Shoveling is static exertion, i.e., you’re standing in one spot and using your upper body to lift heaps of heavy, wet snow. “With this kind of exercise, you see sudden, big increases in heart rate and blood pressure,” says Franklin.
Hoisting and pushing tend to make us hold our breath as we strain, which in turn increases heart rate and blood pressure.
Standing still while you shovel or use the snowblower means that “your heart is running like hell, but you’re not moving your legs, so blood pools in the lower extremities,” explains Franklin. I.e., it’s not getting back up to your heart as readily.
And then there’s the constriction of the arteries of your heart because it’s cold; these are the size of cooked spaghetti to begin with, and get even narrower, he says. That raises blood pressure and means less blood gets to your heart.
What does age have to do with it?
“People don’t run into trouble if they’re 20 or 30 because they haven’t developed coronary artery disease," says Franklin. “But if they’re 45 to 50 or older, with known or hidden heart disease, especially people who are habitually sedentary, this activity is very dangerous.”
