Holiday heart attacks rise as doctors warn of hidden triggers and prevention tips
Experts urge moderation, sleep and movement during holidays to reduce cardiac risk
The holiday season is bringing a rise in heart-related events, with doctors warning of hidden triggers linked to festive stress, overindulgence and weather changes. Health professionals describe a pattern known as holiday heart syndrome, in which heart attacks and abnormal heart rhythms spike around Christmas and New Year’s. Cardiothoracic surgeon Dr. Jeremy London said the uptick is “like clockwork” each year, and he noted Christmas Eve as the highest-risk day. The surge is attributed to a combination of behaviors and conditions common during the holidays: overeating and heavy drinking, reduced physical activity, emotional and financial stress, and the cold that accompanies winter. “Every year, like clockwork, we see a spike in heart attacks around Christmas and New Year’s,” London said. He added that stressors and the pace of the season contribute to risk, and cold weather can cause vasoconstriction, narrowing blood vessels and potentially raising the chance of plaque rupture.
Cardiologists say holiday heart events often revolve around atrial fibrillation, a rapid and irregular heart rhythm that can occur after binge drinking or a heavy meal. Dr. Glenn Hirsch, chief of the division of cardiology at National Jewish Health in Denver, told Fox News Digital that holiday heart syndrome typically refers to this AFib onset. “It’s often a combination of overdoing the alcohol intake along with high salt intake and large meals that can trigger it,” he said. “Adding travel, stress and less sleep, and it lowers the threshold to go into that rhythm.” The biggest risk from AFib is the possibility of stroke and other clot-related complications; untreated AFib can contribute to heart failure over time. Hirsch also noted that age and underlying cardiovascular risk factors—high blood pressure, obesity, diabetes, sleep apnea and chronic kidney disease—raise the likelihood of AFib.
Preventing a holiday heart event is possible, according to Hirsch. He urged moderation as a core guideline for celebrations, advising people to avoid binge drinking, overeating salty foods and dehydration, while managing stress and prioritizing sleep. “Moderation is key,” he said, and he encouraged maintaining physical activity during the holidays. “Don’t forget to exercise. Even getting in at least 5,000 to 10,000 steps during the holiday can help lower risk, while also burning some of the additional calories we are often consuming around the holidays.” London agreed, emphasizing that “movement is medicine” and urging people to stay active each day.
Sticking to a routine remains crucial. London highlighted the importance of continuing prescribed medications and suggested setting reminders during the holiday break. “Prioritize sleep and mindfulness,” he added. “Take care of yourself during this stressful time.” He also warned that many people delay seeking medical care for concerning symptoms until after the holidays, which can worsen conditions. “Don’t ignore your symptoms. If you don’t feel right, respond.”
Health officials emphasize that holiday heart syndrome is preventable with small, consistent steps. The season’s stresses—travel, family obligations, late-night meals and alcohol—do not have to translate into a preventable medical setback. Along with moderation, staying hydrated, maintaining sleep schedules, and keeping physical activity regular, individuals should monitor blood pressure and heart health, particularly if they have known risk factors. Medical professionals recommend planning ahead for meals, budgeting time for rest, and recognizing the signs of AFib—rapid or irregular heartbeat, chest discomfort, lightheadedness or shortness of breath—and seeking prompt care if they occur.
For readers looking to protect heart health through the holidays, clinicians offer a simple framework: balance indulgence with movement, limit alcohol, monitor sodium intake, stay hydrated, maintain medication regimens, and ensure sufficient rest. While the holidays bring unique stresses, they also provide an opportunity to protect long-term heart health through mindful choices and timely medical attention when needed.
The guidance comes as doctors reiterate that holiday heart syndrome is real, measurable and largely preventable with proactive habits. By combining moderation with physical activity, sleep and stress management, people can reduce their odds of a holiday cardiac event and start the new year on a healthier note.
