as the holiday season ramps up,so too does a potentially dangerous,yet often overlooked,cardiac condition known as “holiday heart syndrome.” Cardiologists are reporting a rise in irregular heartbeat cases linked to excessive food and alcohol consumption during festive gatherings, a phenomenon first documented nearly five decades ago [[1]]. While typically temporary, this heart rhythm disturbance can mimic more serious conditions and underscores the importance of mindful indulgence throughout the holidays. Health officials are urging individuals to be aware of the symptoms and seek medical attention when necessary.
The holiday season, with its traditions of festive foods and celebratory drinks, can sometimes take a toll on heart health. Cardiologists are seeing an increase in patients experiencing an irregular heartbeat during and after the holidays, a condition known as “holiday heart syndrome.” This phenomenon highlights the importance of mindful indulgence during a time often associated with overeating and drinking.
Holiday heart syndrome is a heart rhythm disturbance triggered by consuming large amounts of food and alcohol in a short period. “It sounds very cozy, but it isn’t,” explains cardiologist Menno Baars of the HartKliniek. Symptoms can include a rapid, irregular heartbeat – feeling as if you’ve just finished exercising while at rest – shortness of breath, dizziness, and even fainting. Some individuals may also experience chest pain, particularly when the heart rate is elevated.
The condition was first described nearly half a century ago, when doctors noticed a surge in hospital admissions following episodes of “binge drinking” – defined as consuming at least four to five alcoholic beverages in a short timeframe. These incidents were particularly common on weekends and during holidays, as people tend to relax their usual routines and enjoy more alcohol, according to Baars.
But alcohol isn’t the sole culprit. Overindulging in rich, fatty foods like fried snacks and pastries also increases the risk of heart problems and holiday heart syndrome. “Large meals strongly stimulate the nerve that controls the stomach and the heart,” Baars says. “This can cause hormone levels to rise, leading to an increase in heart rate and blood pressure.”
Alcohol disrupts calcium processing in heart cells, which can lead to irregular electrical signals and an erratic heartbeat. It can also disrupt the balance of electrolytes like sodium and potassium, interfering with the brain’s control over the heart. Furthermore, alcohol has a directly toxic effect on heart tissue and can cause lasting damage to heart cells, Baars notes.
Fortunately, holiday heart syndrome usually resolves on its own once alcohol consumption stops. In most cases, a good night’s sleep is enough to restore a normal heart rhythm, with symptoms disappearing the following morning or afternoon.
However, individuals experiencing symptoms should take immediate action. “If you recognize these palpitations, stop drinking alcohol immediately, rest, and schedule an appointment with your doctor. If you experience severe symptoms such as shortness of breath or dizziness, call emergency services,” Baars advises.
The HartKliniek, a national heart disease clinic with locations in Lelystad, Almere and Dronten, and the Flevoziekenhuis in Almere both report seeing an increase in patients with complaints related to overeating and alcohol use during the holiday season, including heart rhythm disturbances and heart failure, according to a hospital spokesperson.
The best way to prevent holiday heart syndrome is to enjoy the festivities in moderation. “What we learn from this? Enjoy the holidays, but do so in moderation. That is the key to a healthy heart,” Baars says. He recommends avoiding or limiting alcohol consumption and definitely avoiding binge drinking. Drinking plenty of water, limiting foods high in fat, sugar, and salt, and avoiding overeating are also crucial steps.
