How Does Cold Weather Affect Your Heart?

Winter can be challenging for your heart health. The seasonal factors may also be responsible for this, like reduced physical activity, stress, and unhealthy eating habits. However, the drop in temperature can cause blood vessels to narrow or constrict in your skin, fingers and toes, so less heat is lost. This narrowing (called vasoconstriction) causes:

• Your blood pressure to go up
• Your heart rate to go up
• Your heart will work harder to pump blood to your body.

“Winter can cause your blood to get thicker and stickier, which leads to blood clots. This can increase the risk of a heart attack or stroke. Heart attacks are more common in winter,” said Dr. Shuvo Dutta, MD, a cardiologist at the CK Birla Hospital, Kolkata (BMB).

Causes of heart attack in winter seasons

Heart attacks are more common in winter due to colder temperatures putting extra strain on the heart. Understanding the causes can help protect your heart during the chilly months.

• Cold Weather: Cold temperatures make blood vessels narrow, increasing blood pressure and straining the heart.
• Extra Work for the Heart: The heart works harder to keep your body warm in cold conditions.
• Reduced Physical Activity: People tend to stay indoors and move less in winter, which can impact heart health.
• Cold or Flu: Illnesses like colds and the flu are common in winter and can put additional strain on your heart.

You may feel concerned about going outside, especially if you have heart-related issues. However, by following a few simple steps, you can enjoy the cold weather without worrying about your heart health. Let’s take a look.

• Don’t overexert yourself in the cold, especially activities like shovelling snow.
