During winter, the chances of heart attacks rise significantly — especially for people who already have heart-related conditions. Here are the major reasons and ways to stay protected:


❇️ Cold Weather Narrows Blood Vessels

In low temperatures, blood vessels shrink to preserve body heat. This increases blood pressure and puts extra strain on the heart.

❇️ Increased Workload on the Heart

To maintain body warmth, the heart has to pump blood more forcefully, making it work harder than usual.

❇️ Stress Caused by Cold Exposure

Cold weather creates physical stress on the body, which can trigger heart-related complications, including heart attacks.

❇️ Sudden Physical Exertion

Performing heavy physical activities suddenly in cold weather can exert excessive pressure on the heart, raising the risk of a heart attack.


💢 How to Stay Safe During Winter

  • Keep your body warm and wear layered, protective winter clothing.
  • Start exercising or doing heavy work gradually — avoid sudden strain.
  • Monitor your blood pressure, cholesterol, and overall heart health.
  • If you already have heart issues, never change your routine without consulting your doctor.
  • If you feel concerned about heart safety during the colder months, seek medical advice promptly.
