While most people won't have a problem, shoveling snow can put some people at risk of heart attack. Sudden exertion, like moving hundreds of pounds of snow after being sedentary for several months, can put a big strain on the heart. Pushing a heavy snow blower also can cause injury.
Cold weather can increase heart rate and blood pressure. It can make blood clot more easily and constrict arteries, which decreases blood supply. This is true even in healthy people. Individuals over the age of 40 or who are relatively inactive should be particularly careful. Follow these tips to shovel safely:
- Do not shovel after eating or while smoking
- Take it slow and stretch out before you begin
- Shovel only fresh, powdery snow; it's lighter
- Push the snow rather than lifting it
- If you do lift it, use a small shovel or only partially fill the shovel
- Lift with your legs, not your back
- Do not work to the point of exhaustion
- Know the signs of a heart attack, and stop immediately and call 911 if you're experiencing any of them; every minute counts
Don't pick up that shovel without a doctor's permission if you have a history of heart disease. A clear driveway is not worth your life.
