Can Shoveling Snow Really Lead to a Heart Attack?

We all enjoy the serene beauty of a fresh snowfall, but with it comes the responsibility of clearing it. Surprisingly, shoveling snow can be riskier than you might think, with around 100 deaths each year and countless injuries.

Shoveling snow can be as physically demanding as a rigorous treadmill workout. Cold weather exercises place additional stress on the body, causing it to burn nutrients more quickly. While dehydration is typically a summer concern, it remains just as dangerous during winter storms, and the chill may make it harder to feel thirsty.

Cold temperatures can also cause coronary arteries to constrict and blood pressure to rise. You've likely heard that shoveling snow can trigger a heart attack, but is that a real risk? Below, we explore the potential dangers of snow shoveling, examining whether it genuinely increases the chance of serious heart issues. Plus, we offer helpful tips to keep your next snow-shoveling session safe.

Is There Really a Risk of Heart Attacks from Shoveling Snow?

Several studies have highlighted the link between shoveling heavy snow and an increased risk of heart attacks or other severe cardiovascular events. The American Heart Association confirms that this is no myth—it's a genuine risk for those who plan to shovel snow themselves this season.

Dr. Barry Franklin, lead author of an American Heart Association paper on physical activity and heart rate, explained, 'The impact is hardest on those who are least fit.' He added, 'This issue is especially concerning for individuals with existing cardiovascular risks such as a sedentary lifestyle, obesity, smoking history, diabetes, high cholesterol, high blood pressure, or those who have experienced a heart attack or stroke.'

During intense physical activity, your heart rate rises and blood pressure can also increase. In one study, after just 10 minutes of snow shoveling, the male participants' heart rates surged to 173 beats per minute, which is 97 percent of their maximum heart rate. To put it in perspective, healthcare experts recommend aiming for a target heart rate of between 50 percent and 85 percent of your maximum while exercising.

Shoveling Snow: What Other Health Risks Should You Be Aware Of?

It’s clear how pushing your heart to its limit during strenuous activity can create undue stress on the organ. However, that’s not the only health hazard you could face if you overexert yourself while shoveling.

Improper posture and lifting techniques when handling heavy snow can lead to lower back pain or even a herniated disc. Prolonged exposure to freezing temperatures can also increase the risk of frostbite on exposed skin, or worse, hypothermia, a dangerous drop in body temperature.

Naturally, slippery surfaces and hard ground create a hazardous mix. Falls can lead to broken bones, torn ligaments, and bruising. Before you start clearing the driveway, consider reviewing the following safe shoveling tips.

How to Shovel Snow Safely

Shoveling snow can be an effective form of exercise during winter, but it’s important to acknowledge the risks involved.

If you're planning to clear your own walkways this season and aren’t hiring someone, there are certain precautions you should consider. Experts recommend the following:

1. Dress in layers to ensure all extremities are properly covered.
2. Before shoveling, avoid large meals, caffeine, and alcohol, as these can raise your blood pressure. However, make sure to drink enough water to stay hydrated.
3. Warm up with stretches or exercises before beginning. If you're not in good physical shape or have a health condition that increases the risk of heart attack or stroke, consult a healthcare professional first and consider asking someone else to shovel for you.
4. Take regular breaks.
5. Use proper lifting techniques: Stand with your feet shoulder-width apart for balance, keep your hands about 12 inches apart, and lift with your legs, not your back. When possible, push the snow rather than lifting it, and avoid throwing snow over your shoulder.
6. If you feel any of the following symptoms, seek medical help immediately: lower back pain, pain down the left arm, chest pain, dizziness, numbness or tingling, irregular heart rhythms, or palpitations.

To stay safe while shoveling snow, it's important to choose the right time. Aim to shovel after 2 to 4 inches of snow have accumulated. Fresh snow is easier to move than snow that has compacted, melted, and refrozen, which can be much more difficult to clear.
