Winter brings beauty, but also challenges. One of the most common tasks during snowy months is shovelling snow. While it may look like a simple chore, cardiologists warn that it can be dangerous for your heart. In fact, heart attacks triggered by snow shovelling often happen within the first 10–15 minutes.
why snow shovelling is risky, what science says, and how you can stay safe.
Why Snow Shovelling Is Risky
- Sudden exertion: Most people are not physically prepared for the intense effort of lifting heavy, wet snow.
- Cold weather impact: Low temperatures cause blood vessels to narrow, increasing blood pressure.
- Breath-holding strain: Many people hold their breath while lifting, which spikes pressure inside the chest.
- Rapid heart stress: The combination of cold, exertion, and strain can overwhelm the heart quickly.
The Science Behind Heart Strain
Doctors explain that snow shovelling is not like regular exercise. Unlike jogging or walking, it involves:
- Short bursts of heavy lifting.
- Twisting and bending movements.
- Sudden spikes in blood pressure.
- Reduced oxygen intake due to breath-holding.
This makes it more similar to weightlifting under extreme conditions — something most people’s bodies are not trained for.
Who Is Most at Risk
- People with existing heart disease.
- Those with high blood pressure or cholesterol.
- Smokers and diabetics.
- Individuals who are usually inactive but suddenly shovel snow.
- Men over 40, especially those who treat shovelling like a workout challenge.
Warning Signs to Watch For
If you feel any of these while shovelling, stop immediately:
- Chest pain or tightness.
- Shortness of breath.
- Dizziness or lightheadedness.
- Pain spreading to arms, neck, or jaw.
- Sudden sweating or nausea.
Safe Snow Shovelling Tips
- Warm up first: Stretch or walk for a few minutes before starting.
- Dress warmly: Keep your body insulated to reduce vessel constriction.
- Push, don’t lift: Slide snow instead of lifting heavy piles.
- Take breaks: Rest every few minutes, especially in the first 10 minutes.
- Stay hydrated: Cold weather can still dehydrate you.
- Listen to your body: Stop if you feel discomfort.
Alternatives to Shovelling
- Use a snow blower if possible.
- Ask for help from younger or fitter family members.
- Hire local services for heavy snowfalls.
- Spread salt or sand to reduce the need for constant clearing.

A Cardiologist’s Advice
Dr. Dmitry Yaranov emphasizes:
- Don’t treat snow shovelling like a gym workout.
- Avoid rushing or competing with yourself.
- The first 10 minutes are the most dangerous — pace yourself.
- Focus on safety, not speed.
Lifestyle Choices That Protect Your Heart Year-Round
- Regular moderate exercise (walking, cycling, swimming).
- Balanced diet rich in fruits, vegetables, and whole grains.
- Avoid smoking and limit alcohol.
- Manage stress through meditation or yoga.
- Regular health check-ups to monitor blood pressure and cholesterol.
Conclusion
Snow shovelling may look harmless, but it can be one of the most dangerous winter chores for your heart. Treat it carefully, pace yourself, and remember: protecting your health is more important than clearing the driveway quickly. Winter safety is not about strength — it’s about smart choices.
