Twinkling lights, family gatherings and holiday cheer often come with indulgent meals and celebratory drinks.
But cardiologists at Houston Methodist are sounding the alarm on a little-known condition that can turn festivities into a health scare: Holiday Heart Syndrome.
This temporary heart rhythm disturbance, most commonly atrial fibrillation (AFib), can strike even healthy individuals after binge drinking, overeating, dehydration and stress. Symptoms include rapid or irregular heartbeat, chest fluttering, dizziness and shortness of breath—often appearing 12–36 hours after heavy alcohol consumption.
“The holidays create a perfect storm for rhythm problems. Even people with no prior heart issues can suddenly experience irregular heartbeats,” said Dr. Bindu Chebrolu, cardiologist at Houston Methodist.
Who’s at risk?
While anyone can experience Holiday Heart Syndrome, risk increases with age, high blood pressure, obesity, diabetes, sleep apnea and heavy alcohol intake. Even one night of excessive drinking can trigger AFib in otherwise healthy individuals.
Why it matters
Untreated AFib can lead to stroke, heart failure and long-term complications. Studies show repeated binge drinking episodes can convert temporary rhythm disturbances into chronic AFib, significantly increasing cardiovascular risk.
Prevention tips
Hydrate well and pace your drinks
Prioritize sleep and avoid salty holiday meals
Don’t mix alcohol with energy drinks
Use smartwatches to monitor heart rate if prone to palpitations
“The best way to avoid Holiday Heart Syndrome is to drink in moderation—or skip alcohol altogether if you have high blood pressure, atrial fibrillation or diabetes,” Chebrolu said.
When to seek help
Persistent irregular heartbeat, chest pain, fainting or severe shortness of breath require immediate medical attention. Even if symptoms resolve, it is a good idea to schedule an appointment with a cardiologist.
