Experts Warn: Heart Attacks Rise During the Festive Season

Do Heart Attacks Really Increase During the Holidays? Experts Say Yes.

The holiday season may bring joy, celebration, and long-awaited time with loved ones — but cardiologists warn it also brings a surprising spike in heart attacks. According to the American Heart Association, the last week of December consistently sees more heart attacks than any other time of year. A combination of cold weather, heavier meals, increased stress, and delayed medical care all play a role in this seasonal trend.

Why the Risk Rises in December

Cold temperatures alone can put added strain on the heart, as blood vessels constrict and blood pressure increases. But physicians say lifestyle shifts during the holidays have an even greater impact. Many people overindulge in rich meals, fatty foods, and sugary treats — a mix that can trigger inflammation and elevate risk for those with underlying conditions.

Alcohol consumption also tends to rise, and with it comes what experts call “holiday heart syndrome,” a temporary but dangerous form of irregular heartbeat linked to binge drinking. This disruption of the heart’s electrical rhythm can lead to atrial fibrillation and, in severe cases, a heart attack.

Stress is another major contributor. From family dynamics to frantic shopping, cortisol levels often climb during December — putting the heart under extra pressure at the exact moment many people begin ignoring symptoms they would normally take seriously. Chest discomfort, fatigue, nausea, and shortness of breath are too often dismissed as overeating or holiday exhaustion.

How to Protect Yourself — and What to Do in an Emergency

Doctors emphasize that quick action saves lives: call 911 immediately if heart attack symptoms appear. Aspirin, prescribed nitroglycerin, loosening tight clothing, and lying down while waiting for help can improve outcomes.

Preventative care matters most. Heart-healthy meals, regular exercise, managing stress, avoiding smoking, and keeping blood pressure in check can dramatically reduce risk — during the holidays and throughout the year.
