WAUSAU, WI (OnFocus) – As temperatures drop, the risk of heart-related health issues, particularly heart attacks, rises significantly. Research has highlighted the connection between cold weather and cardiovascular events, raising concern for individuals in colder climates or facing sudden temperature changes.
Cold weather poses unique challenges for the body. “When temperatures fall, our bodies respond by constricting blood vessels to conserve heat, which can raise blood pressure,” said Dr. Daniel Krause, an Aspirus Heart Care cardiologist. “This added strain on the heart can be especially dangerous for individuals with preexisting heart conditions or those at risk of cardiovascular disease.”
Why Cold Weather Increases Risk
Cold weather impacts the cardiovascular system in several ways:
- Vasoconstriction: The narrowing of blood vessels increases blood pressure, forcing the heart to work harder.
- Increased Blood Clotting: Cold temperatures can cause blood to thicken, which may elevate the risk of clot formation.
- Elevated Heart Rate: Activities like shoveling snow or outdoor exercise can strain the heart, especially for those unaccustomed to such exertion.
- Decreased Oxygen Supply: Cold air can irritate the lungs, reducing oxygen levels and increasing cardiac strain.
Who Is Most at Risk?
Certain groups are more vulnerable to cold-weather-related heart issues, including:
- Older adults
- Individuals with existing cardiovascular disease
- Smokers
- Those with high blood pressure or diabetes
- People engaging in sudden, strenuous outdoor activities
Recognizing the Warning Signs
Recognizing the signs of a heart attack is crucial. Symptoms to watch for include:
- Chest pain or discomfort
- Shortness of breath
- Pain radiating to the arm, neck, or jaw
- Cold sweats or lightheadedness
“If you or someone you’re with experiences these symptoms, call 911 immediately,” Dr. Krause emphasized. “Quick action can save lives.”
Aspirus encourages the community to take simple precautions to protect their heart health, such as dressing warmly, avoiding sudden physical exertion outdoors, and staying hydrated. For more information or to connect with an Aspirus cardiologist, visit Aspirus.org.
