Why are heart attacks more common at Christmas? Doctor explains winter wave and warning signs

As the holiday season brings festive joy and celebration, beware of the secret risk that quietly emerges on Christmas Day. Well, it’s not the Grinch stealing the decorations, but a life-threatening situation.

According to the American Heart Association, heart attacks strokes spike in the last two weeks of December, and December 25 is the peak year for cardiac events. Dr. Patricia Vassallo, a cardiologist at Northwestern Medicine, explains that the increased risk during the winter months comes from a combination of cold weather, holiday stress and disruptions to daily routines.

“Cold temperatures cause blood vessels to constrict, which increases blood pressure and makes the heart work harder to pump blood. At the same time, the stress of the holidays and disrupted routines – such as less sleep, more alcohol and skipping medications – increase stress. Excessive exertion from winter chores such as shoveling heavy snow can further increase the risk, especially for people with existing heart disease.” he said Dr. A. S. Wasallo.

The holidays may not be a time of joy for everyone, and may cause feelings of stress or sadness as a result of mourning the loss of loved ones, organizing large gatherings, or dealing with complex family dynamics. Emotional and physical stress have a significant impact on heart health, which is why the number of heart attacks and strokes spikes on Monday mornings, when stress levels are highest, Dr. Vassallo said.

How to reduce your risk:

Since cold weather, increased stress, and changes in routine are key factors in the winter increase in cardiac events, Dr. Vassallo recommends following specific tips to reduce your risk.

1. Dress for the weather: To stay warm on cold days, wear layers and use essential accessories like hats, gloves and thick socks.

2. Come inside often: SBeing outdoors in the cold for long periods of time can increase the risk of hypothermia and heart attack. If you must spend time outdoors, remember to take breaks inside to warm up.

3. Avoid excess alcohol: Although alcohol seems to give you a temporary feeling of warmth, it can lower your body temperature and make you more susceptible to cold.

4. Don’t shovel snow for a long time: Shoveling snow is an activity that puts extra strain on your heart, especially if you have a pre-existing heart condition. It is important to check with your doctor whether shoveling snow is safe or whether you should limit this activity.

5. Wash your hands often: Respiratory infections are common during the winter months and may increase the risk of heart attack. Washing your hands frequently helps reduce the spread of germs and infections.

6. Get help: If you experience any new symptoms of heart disease or existing symptoms become worse, do not hesitate to seek medical attention, even if it is a holiday.

Signs to look out for:

Knowing the symptoms of heart attacks and strokes can save your life. It is important to seek medical help immediately if you notice symptoms such as severe chest pain, nausea, dizziness, shortness of breath, pain or numbness in the jaw, back, neck or arms, cold sweat, heartburn or sudden tiredness.
