The holidays are a joyful time for many. Families gather, lights sparkle, and feasts are shared. But behind the celebration lies a hidden risk for heart health that few talk about. Doctors are warning of a rise in heart attacks during the holiday season, caused by behaviors many people see as harmless.
This increase in heart attacks is called “holiday heart syndrome,” a phenomenon that occurs when the heart experiences sudden stress from lifestyle changes around the holidays. Cardiothoracic surgeon Dr. Jeremy London recently explained this risk on Instagram, sharing that heart attacks spike every year during Christmas and New Year’s.
“Every year, like clockwork, we see a spike in heart attacks around Christmas and New Year’s,” Dr. London said. “In fact, Christmas Eve is the highest-risk day of the year.”
So why does this happen? Dr. London explained that changes in daily routines play a major role. Drinking too much alcohol, overeating, skipping exercise, and feeling stressed are key triggers.
“Emotional stress, financial stress, the increased pace of the holidays, increased obligations,” London said, listing the main pressures that affect the heart.
Cold winter weather also adds to the risk. Dr. London explained that cold temperatures cause vasoconstriction, or narrowing of blood vessels, which increases the chance of plaque rupture—a common cause of heart attacks.
Dr. Glenn Hirsch, chief of cardiology at National Jewish Health in New York, noted in an interview with Fox News Digital that holiday heart syndrome often shows up as an abnormal heart rhythm called atrial fibrillation.
“This can happen after an episode of binge-drinking alcohol, which is common during holiday celebrations,” Dr. Hirsch said.
He added that the combination of heavy alcohol intake, high-salt meals, and large feasts can trigger abnormal heart rhythms. “Add travel, stress, and less sleep, and it lowers the threshold to go into that rhythm,” Hirsch explained.
Atrial fibrillation is dangerous because it increases the risk of stroke and other complications from blood clots. Untreated, it can even lead to long-term heart failure.
“The risk increases with age, but also underlying conditions like high blood pressure, obesity, diabetes, sleep apnea, and chronic kidney disease make it more likely,” Dr. Hirsch said.
Thankfully, holiday heart syndrome is preventable. Moderation is key. Dr. Hirsch stressed the importance of avoiding binge drinking, overeating, dehydration, and unmanaged stress, while prioritizing sleep.
“Don’t forget to exercise,” he added. “Even getting in at least 5,000 to 10,000 steps during the holiday can help lower risk while burning some of the extra calories we often consume.”
Dr. London also emphasized movement, calling it “medicine.” He encourages people to stay active every day, even during holiday breaks.
“Prioritize sleep and mindfulness,” London added. “Take care of yourself during this stressful time.”
He also warned that many people delay addressing health concerns until after the holidays, which can make conditions worse.
“Don’t ignore your symptoms,” he said. “If you don’t feel right, respond.”
Staying on schedule with medications is another key preventative step. Dr. London recommends setting reminders to avoid missed doses, even during busy holiday periods.
Managing stress is equally important. Practicing relaxation techniques, taking short walks, and limiting exposure to stressful situations can all help protect the heart.
Traveling can also increase heart risk if it disrupts sleep or leads to missed meals. Doctors suggest planning ahead and keeping routines as consistent as possible.
Families can also help each other. Hosting moderate meals, encouraging short walks, and creating low-stress celebrations can reduce holiday heart risks for everyone.
Hydration is often overlooked. Drinking plenty of water can counter the effects of alcohol, heavy meals, and salty foods, all of which strain the heart.
Even small lifestyle adjustments, like standing during long gatherings, using stairs, or taking a short evening walk, can make a significant difference in heart health during the holidays.
In short, enjoying the holidays safely means combining moderation with mindful living. Doctors remind us that celebrations are meant to bring joy, not heartache.
If you or someone you know feels unusual chest discomfort, palpitations, or extreme fatigue, don’t wait until after the holidays. Seek medical attention immediately.
By staying active, eating mindfully, managing stress, and prioritizing sleep, you can enjoy the season while protecting your heart. Holiday heart syndrome may be common, but it is preventable with awareness and care.
