Shoveling snow looks harmless enough, but for many people, it can quietly become one of the most dangerous chores of winter. Every year, emergency rooms see a spike in heart-related incidents after major snowstorms—and it’s not a coincidence.
Here’s what makes snow shoveling risky, who needs to be extra cautious, and how to protect yourself if you do have to grab a shovel.
Why Snow Shoveling Is So Hard on Your Heart
Snow shoveling isn’t just a chore—it’s intense physical exercise. Lifting heavy, wet snow repeatedly can send your heart rate and blood pressure soaring, especially if you’re not used to strenuous activity.
Cold weather adds another layer of risk. Low temperatures can cause blood vessels to constrict, which makes your heart work even harder. Together, heavy exertion and cold air create a perfect storm for cardiac strain.
Studies cited by the American Heart Association show higher rates of heart attacks and sudden cardiac deaths immediately following snowstorms—particularly among people who are older or inactive.
Who Should Think Twice Before Shoveling
Not everyone needs medical clearance before exercise, but snow shoveling isn’t a casual workout. If you don’t regularly engage in intense physical activity, you should be cautious—especially if you have:
-
Heart disease or a history of heart attack or stroke
-
Diabetes or kidney disease
-
High blood pressure or high cholesterol
-
Obesity
-
A history of smoking
-
A mostly sedentary lifestyle
If this sounds like you, it’s worth talking to a doctor before tackling heavy snow. The risk applies whether the activity is shoveling, running, or pushing through six inches of packed snow.
Yes, Snowblowers Count as Exercise Too
It’s easy to assume snowblowers are safe because they do the heavy lifting—but pushing one still requires significant effort. Studies show that snowblowing can also elevate heart rate and blood pressure, though it’s usually less taxing than manual shoveling.
If you’re choosing between the two, snowblowing is generally easier on your body—but it’s not risk-free.
How to Lower Your Risk While Clearing Snow
If you’re healthy enough to shovel, a few smart habits can dramatically reduce your risk:
-
Shovel early and often. Clearing two inches at a time is far safer than waiting for six.
-
Push snow instead of lifting it whenever possible.
-
Take frequent breaks and pace yourself.
-
Dress warmly, but avoid overheating.
-
Listen to your body. Fatigue is a warning sign, not a challenge.
Most importantly, stop immediately if you experience chest pain, pressure, dizziness, shortness of breath, or heart palpitations. If symptoms don’t quickly go away, call emergency services.
As the American Heart Association puts it: Don’t try to push through warning signs—your life is more important than a clear driveway.
The Bottom Line
Snow shoveling may seem routine, but for some people, it’s a serious cardiac stressor. Knowing your personal risk—and adjusting how, when, or whether you shovel—can prevent a dangerous emergency.
When in doubt, ask for help, hire assistance, or let the snow wait. Winter chores aren’t worth risking your heart.
