Heart attacks rise sharply during the holiday season, and a Redwood City doctor is urging residents to take precautions as December and January consistently see the highest rates of cardiac deaths nationwide.
Research from the American Heart Association shows cardiac mortality peaks around Christmas and New Year’s, a pattern local physicians say they see reflected in San Mateo County.

“The holiday season brings more than just cheer, it also brings a perfect storm of stressors,” said Dr. Carol Chen, MD, director of cardiac surgery at Sequoia Hospital in Redwood City. “From heavy meals and disrupted sleep to concerns over finances, travel, anxiety, and cold weather, these factors can take a serious toll on your heart. For many, this combination significantly raises the risk of heart attacks and other cardiac events.”
Doctors cite a mix of cold weather, heavier eating, alcohol use, travel and emotional stress. Irregular schedules can also disrupt medications, sleep and physical activity. Emergency rooms nationwide report increased cardiac calls from Thanksgiving through New Year’s.
Redwood City tips for staying safe
Chen said one of the most effective ways to lower risk is to stay consistent with basic self-care, even when the season feels hectic.
“Start with just one healthy choice each day — whether it’s a heart-smart breakfast, a brisk walk, or taking a moment to breathe and de-stress,” she said. “These small, consistent actions can protect your heart and even save your life over time.”
Studies show more than half of annual weight gain occurs between Thanksgiving and New Year’s, with many people adding 5 to 7 pounds during the season. Because excess weight is closely linked with heart disease, the American Heart Association recommends filling your plate with vegetables first, watching portion sizes and limiting high-calorie foods and alcohol.
Lifestyle changes that lower risk
The AHA says up to 80% of heart disease is preventable through daily habits such as:
- Quitting smoking
- Getting about 30 minutes of physical activity most days
- Eating a heart-healthy diet
When to call for help
Anyone experiencing chest pain, shortness of breath, nausea, fainting or pain radiating to the arm or jaw should call 911 immediately.
