Cardiologist warns this common winter activity can trigger heart problems, even in healthy people; shares warning signs

Cold weather and sudden effort can quietly strain the heart. Cardiologist Dr Dmitry Yaranov explains why a common winter activity may be riskier than it looks.

The cold of winter can make getting active feel like a challenge, but many of us still try to jump into outdoor chores or intense workouts to stay fit. What seems like a simple way to start the season on a healthy note can actually put your heart under serious strain.

According to Dr Dmitry Yaranov, MD, cardiologist who specialises in heart failure and heart transplantation, some winter activities are more dangerous than you might think, especially as your body adjusts to the cold.

How winter chores can strain your heart

Dr Dmitry shares in his January 6 Instagram post, “Snow shovelling isn’t exercise. It’s an unplanned cardiac stress test. Cold exposure causes blood vessels to constrict, which raises blood pressure even before you lift the shovel. Then comes the heavy, isometric effort, breath-holding, and sudden bursts of strain."

“Heart rate rises. Oxygen demand spikes. Coronary flow can’t always keep up,” Yaranov explains. Every winter, the same pattern emerges: people who felt “fine” all year suddenly experience chest pressure, shortness of breath, dizziness, or even collapse while shovelling. “Sometimes it’s the first sign of coronary disease. Sometimes it’s the last straw in someone with known heart disease,” he adds.

Warning signs to stop immediately

• Chest tightness or pressure
• Unusual shortness of breath
• Lightheadedness or nausea
• Pain radiating to the jaw, arm, or back

“Pace yourself. Take breaks. Push snow instead of lifting when possible,” Yaranov advises. “And if you have known heart disease, or risk factors, letting someone else shovel is not weakness. It’s good judgment. Your heart doesn’t care about the driveway. It cares about oxygen and blood flow.”
