Heavy Snowfall Sparks Heart Attack Alarms: The Hidden Dangers of Shoveling
When a blizzard hits, we're warned to stay indoors and wait for the storm to pass. But what happens when the snow is heavy and wet – dubbed "heart attack snow" by meteorologists? For many people, shoveling snow can become a deadly task.
A study published in 2011 found nearly 200,000 U.S. residents were treated in emergency departments for snow-shovel related injuries between 1990 and 2006. Moreover, nearly 1,650 cardiac-related deaths were recorded during that time period. Canadian researchers have also warned of the dangers of shoveling heavy snow, with storms dumping at least 7-8 inches increasing the risk of men being hospitalized for heart attacks by 16% and dying from them by 34%.
So why is shoveling snow so hazardous to the heart? Dr. Benjamin Rosenfeld, a cardiologist at Jefferson Einstein Montgomery Hospital, explained that shoveling can unmask pre-existing cardiac disease in people who are typically sedentary or minimally active. The intense physical task required for clearing heavy snow can push an already strained cardiovascular system over the edge.
Furthermore, cold, dry air can cause vasoconstriction – a tightening of blood vessels – which puts more strain on the heart and lungs, particularly for individuals with pre-existing heart or lung disease.
Even healthy, fit people are at risk. Dr. Rosenfeld cautioned that shoveling snow is a defined task that requires physical effort, but it's not like exercising until you feel tired. The mental pressure to complete the task can lead people to push their bodies beyond what's safe and comfortable.
The American Heart Association advises individuals with pre-existing heart or lung disease and those with risk factors for heart disease – such as high blood pressure, diabetes, cigarette smoking – to take precautions when shoveling snow. If you're heading out to shovel, Dr. Rosenfeld recommends hiring someone or having a younger family member help you.
Most importantly, listen to your body. If symptoms persist, don't ignore them. Take breaks frequently, warm up before starting, and drink plenty of water. Don't feel obligated to clear every speck of snow – prioritize your health.
Harvard Health offers additional tips for safe shoveling:
• Warm up before shoveling
• Shovel light loads instead of heavy ones
• Take frequent breaks
• Drink plenty of water
• Prioritize clearing only the essential areas
• Stop immediately if symptoms occur, and call 911 or your local emergency number.
