Shoveling snow in the cold can strain the heart - Shoveling snow could trigger a deadly heart attack in cold weather

Shovelling snow can put serious strain on the heart, especially in cold weather. The mix of heavy exertion and freezing temperatures raises the risk of heart attacks for some people. Experts warn that certain groups face higher dangers when clearing snow by hand.

Cold air causes blood vessels to narrow, increasing blood pressure. This forces the heart to work harder, pumping against greater resistance. At the same time, shovelling involves sudden, strenuous movements that further stress the cardiovascular system.

The combination of cold and physical effort can reduce blood flow to the heart muscle. In extreme cases, this may trigger a heart attack. Studies suggest that snow shovelling can raise heart attack risk by up to 16%, based on data from Austria. On days with extreme cold, global mortality from heart attacks jumps by about 33%.

Those most at risk include people with existing heart conditions, a history of heart attacks, or low fitness levels. Even without prior issues, the sudden demand on the heart can be dangerous. To lower the risk, experts recommend warming up before starting, working at a steady pace, and lifting smaller amounts of snow. Taking frequent breaks also helps reduce strain.

While no exact German figures exist for snow-related heart emergencies, research confirms the added risks. Cold weather and heavy shovelling create a double burden on the heart. Simple precautions—like pacing work and avoiding overexertion—can make clearing snow safer.
