Snow Shoveling: Not for the Faint of Heart

Digging out of winter’s latest snow is taxing, and not for the faint of heart. In fact, depending on the water content of the snow, the weight per cubic foot can range from just over 3 pounds for fluffy snow to a heart pounding 20-plus pounds for wet snow.

“Whether you are in shape or not, shoveling snow is exerting work,” says Lehigh Valley Health Network cardiologist Benjamin Sanchez Jr., MD, with LVPG Cardiology–1250 Cedar Crest in Allentown. “And the more sedentary you are, the greater the impact on your heart when you shovel.”

A 2010 study looked at the incidence of snow shoveling injuries in the United States over a 17-year period. It found that about 11,500 people end up in the emergency room each winter due to shoveling injuries, most in the muscle strain and slip-and-fall categories. While heart attacks accounted for just under 7 percent of emergency room visits during the study time period, they were responsible for 100 percent of snow-shoveling-related deaths.

“Several factors come into play when you shovel,” Sanchez says. “The weight of the snow, coupled with the cold air, plus any risk factors you may have, could trigger a heart attack.”

Gauge your snow shoveling risk factors:

If you answer “‘yes” to any of these, you need to talk to your doctor about whether shoveling snow is appropriate for you.

“Snow shoveling is an aerobic activity, and in some instances would be considered a high-intensity aerobic exercise,” Sanchez says. “The sudden demand on the cardiovascular system caused by shoveling increases blood pressure, and that pressure can rupture cholesterol plaque that may line your arteries. If that happens, the plaque or a clot can block blood flow to the heart, causing a heart attack.”

If you are shoveling, pay attention to your body for signs of trouble.

Symptoms that demand attention:

  • Chest discomfort or pain that lasts more than a few minutes
  • Discomfort or pain in one or both arms, the back, neck, jaw or stomach
  • Shortness of breath with or without chest discomfort
  • Cold sweats
  • Nausea
  • Lightheadedness

If you or someone you are with experiences any of these symptoms while shoveling (or elsewhere) call 911.

“Don’t wait for the next snowstorm – talk to your doctor if you have any risk factors,” Sanchez says. “And if you do, my advice is: don’t push yourself. Instead, pay a teen or a neighbor to handle your shoveling. It is simply not worth taking a chance with your life.”

You could save someone’s life with just two simple things you always have with you: your hands. In the video below Lehigh Valley Health Network (LVHN) emergency medicine physician David Burmeister, DO, with LVPG-Emergency Medicine, and LVHN cardiologist Nainesh Patel, MD, with LVPG Cardiology, show and explain how to do Hands-Only CPR.
