Winter brings snow sports, snowball fights, and the joy of building snowmen, but it can also be hazardous for many people who are at risk for heart attacks.

Cold weather and physical exertion can cause the heart to work harder, increasing the risk for a heart attack, or myocardial infarction (MI). Snow shoveling is a task that many people take for granted, not realizing the danger it poses.

In this article, we will explore the risk of MI during the winter months, how snow shoveling increases that risk, and what you can do to reduce your risk of an MI.

What Happens to the Heart in Cold Weather?

The heart is a muscle that pumps blood throughout your body. When you are exposed to cold weather, your body constricts its blood vessels to conserve heat. This causes an increase in blood pressure, which puts more stress on the heart.

For people who have underlying heart disease, this additional stress can be dangerous. In addition, blood clots are more likely to form in cold weather, which can also lead to an MI.

What is an MI?

When blood flow to a part of the heart is blocked, an MI occurs. This can cause heart damage or even death. The symptoms of an MI can be different for each person, but some common symptoms include chest pain, shortness of breath, and fatigue.

If you experience these symptoms and think you might be having an MI, seek medical attention right away. Time is critical in treating an MI, and early intervention can save your life.

Why is Snow Shoveling Dangerous?

Snow shoveling is a task that requires considerable physical exertion. It can be particularly dangerous for older adults and people with heart disease, as the sudden, intense activity puts a strain on the heart.

In fact, snow shoveling has been shown to increase the risk of MI significantly. A study published in the American Journal of Emergency Medicine found that for people with pre-existing heart conditions, snow shoveling was associated with a 17-fold increased risk of MI.

Reducing Your Risk of Infarction During Snow Shoveling

While snow shoveling can be dangerous, there are things you can do to reduce your risk of an MI. Here are some tips:.

Dress appropriately: Dress in layers so you can remove clothing if you get too warm. Make sure to wear a hat and gloves to keep your extremities warm.
Take frequent breaks: Take a break every 10-15 minutes to rest and catch your breath. Use this time to stretch your muscles and hydrate.
Use a smaller shovel: Use a smaller shovel so you don’t have to lift as much snow with each scoop. Consider using an ergonomic shovel, which can help reduce strain on the back and shoulders.
Push rather than lift: Whenever possible, push the snow rather than lifting it. This uses less energy and puts less strain on your heart.
Know your limits: Listen to your body and stop if you feel tired or short of breath.

Conclusion

The risk of MI is higher during the winter months, and snow shoveling is a key risk factor. By taking precautions and following the tips outlined above, you can reduce your risk of an MI while shoveling snow.

If you have a pre-existing heart condition, it is especially important to talk to your doctor before engaging in any physical activity that puts a strain on your heart. Stay safe and enjoy the winter wonderland!.
