Why Heart Attacks Increase in The Winter

Why Heart Attacks Increase in The Winter

Cooler Temperatures and Cardiovascular Disease

As the temperature continues to drop, the risk of experiencing a heart attack is on the rise—but why? Here’s what you should know to help reduce your risk of experiencing heart attack this snowy season.


When your body is exposed to frigid temperatures, it can cause the blood vessels in your heart to constrict to the point where oxygen and blood flow are restricted. In order to combat this sudden shock to your heart, be sure to wear the appropriate outerwear and protective gear when you head out into the elements, such as:

  • A warm hat
  • A thick winter jacket
  • A scarf
  • Gloves


While bundling up is important to protect your body against harsh temperatures, it is also important to avoid overheating. When your body begins to reach dangerous temperatures, your body needs to able to cool itself down or you can experience a significant drop in blood pressure, triggering a heart attack.

To prevent overheating, dress in layers so you can remove clothing to cool down temporarily and put them back on to retain heat.


Whether you’re shoveling your walkway or walking quickly to get out of the cold, there is an increased potential for overexertion. This is because performing everyday tasks that exert energy increases your heart’s need for oxygen. However, if there is a slight blockage in a coronary artery, oxygen supply may not meet the amount needed.

It is important to understand your body’s limits and practice good judgment when it comes to performing outdoor activities, especially if you are at increased risk for heart disease.
