Cold Air and Your Heart: Why Winter Weather Can Trigger Cardiac Events

Cold Weather And Your Heart

Winter in Southern Colorado is a magical time. The crisp mountain air, the snow-dusted peaks, and the cozy evenings spent by the fireplace all contribute to the season’s charm. But as temperatures plummet, it’s crucial to recognize the potential impact of cold weather on your cardiovascular health. At Colorado Springs Cardiology and Southern Colorado Heart and Vascular, we want to ensure you stay heart-healthy throughout the winter months, so you can continue to enjoy everything our beautiful region has to offer.

The Chilling Truth: How Cold Affects Your Heart

It’s not just an old wives’ tale – cold weather really can affect your heart. Here’s why: 

  • Vasoconstriction: When exposed to cold temperatures, your blood vessels constrict, a process called vasoconstriction. This is your body’s attempt to conserve heat and maintain a stable core temperature. However, this constriction also narrows the blood vessels, increasing blood pressure. For individuals already at risk for heart disease, this added strain can be significant. 
  • Increased Blood Clotting: Cold weather can also make your blood more prone to clotting. This is because the body releases more clotting factors in response to the cold. While this is a natural defense mechanism, it can increase the risk of heart attack and stroke, especially for those with existing arterial plaque. 
  • Increased Heart Rate: Shivering, another natural response to cold, increases your heart rate. While a slight increase is normal, a sustained elevated heart rate puts additional stress on the heart. 
  • Exertion and Overexertion: Winter often brings snow shoveling, a strenuous activity that can quickly overtax the heart, especially in colder temperatures. The combination of cold-induced vasoconstriction and physical exertion creates a perfect storm for cardiac events. 
  • Flu and Respiratory Infections: Winter is also flu season. Respiratory infections, like the flu and pneumonia, can increase inflammation in the body, which can destabilize plaque in arteries and raise the risk of heart attack and stroke. 

Who is Most at Risk?

While everyone should take precautions in cold weather, certain individuals are more vulnerable to cold-related cardiac events: 

  • Individuals with Existing Heart Conditions: Those with coronary artery disease, heart failure, arrhythmias, or other cardiovascular issues are at higher risk. 
  • Older Adults: Aging bodies are less efficient at regulating temperature and adapting to cold weather. 
  • People with High Blood Pressure: Cold-induced vasoconstriction can exacerbate hypertension, increasing the risk of heart attack and stroke. 
  • Smokers: Smoking damages blood vessels and impairs their ability to constrict and dilate properly, making smokers more susceptible to the effects of cold weather. 
  • Those Who are Physically Inactive: Lack of physical activity can weaken the cardiovascular system, making it less resilient to stress. 

Southern Colorado-Specific Considerations

Living in Colorado Springs, Pueblo, Canon City, and the surrounding areas presents unique challenges when it comes to cold weather and heart health: 

  • Altitude: Our high altitude means thinner air, which puts additional strain on the heart and lungs. 
  • Extreme Temperature Swings: Colorado is known for its unpredictable weather. Sudden drops in temperature can catch people off guard and increase the risk of cardiac events. 
  • Outdoor Activities: We love our outdoor activities in Southern Colorado, but it’s important to be mindful of the risks of overexertion in cold weather, especially when skiing, snowboarding, or hiking.

Staying Heart-Healthy This Winter: Practical Tips from Colorado Springs Cardiology and Southern Colorado Heart and Vascular

Here are 10 steps you can take to protect your heart during the winter months: 

  1. Dress Warmly: Layer your clothing to trap heat and protect yourself from the cold. Don’t forget a hat, gloves, and scarf to protect your extremities. 
  2. Limit Time Outdoors: Avoid prolonged exposure to cold temperatures, especially if you are at high risk. 
  3. Avoid Overexertion: Be careful when shoveling snow or engaging in other strenuous activities. Take frequent breaks and dress warmly. If you experience chest pain, shortness of breath, or dizziness, stop immediately and seek medical attention. 
  4. Stay Hydrated: Drink plenty of fluids to prevent dehydration, which can thicken the blood and increase the risk of clotting. 
  5. Avoid Alcohol and Caffeine: These substances can interfere with your body’s ability to regulate temperature. 
  6. Monitor Your Blood Pressure: If you have high blood pressure, check it regularly and work with your doctor to keep it under control. 
  7. Get a Flu Shot: Protect yourself from respiratory infections by getting vaccinated against the flu. 
  8. Manage Stress: Stress can exacerbate heart conditions. Practice relaxation techniques like yoga, meditation, or deep breathing exercises. 
  9. Know the Symptoms of a Heart Attack: Be aware of the warning signs of a heart attack, which include chest pain or discomfort, shortness of breath, nausea, light-headedness, and pain or discomfort in the arms, back, neck, jaw, or stomach. If you experience any of these symptoms, call 911 immediately. 
  10. Consult Your Doctor: Talk to your doctor about your individual risk factors and what you can do to protect your heart this winter.
