While the holiday season is often considered the merriest time of the year, it can also bring an increased risk of heart attacks and strokes, health experts warned.
This phenomenon was first highlighted by cardiologist Robert Kloner in his 2004 study, “Merry Christmas Coronary and Happy New Year Heart Attack,” which found a marked rise in cardiac-related deaths during the winter holidays.
Kloner’s findings linked the seasonal spike to a combination of factors, including overeating, excessive alcohol intake, emotional stress, and delays in seeking medical care.
In light of these risks, internist-cardiologist Tony Leachon urged the public to enjoy the holidays while remaining mindful of their health.
Leachon advised Filipinos to limit salty, fatty, and sugary foods, and to balance festive meals with vegetables and lean protein.
He noted that holiday fare is often rich in saturated fats, salt, and sugar. Processed meats, creamy sauces, and desserts can raise blood pressure and cholesterol levels, while refined carbohydrates can cause blood sugar spikes.
"These indulgences, when combined with stress and fatigue, place acute strain on the heart and blood vessels," he said in an interview with the Daily Tribune.
"Alcohol consumption also surges during the season. While once thought to have protective effects in moderation, recent evidence and [World Health Organization] guidance emphasize that no amount of alcohol is truly safe," he added.
Leachon said even small amounts of alcohol increase cancer risk, while binge drinking can trigger heart rhythm disturbances known as “Holiday Heart Syndrome,” where sudden atrial fibrillation may lead directly to stroke.
"[So it is important to] drink responsibly—or not at all: Avoid binge drinking; alternate alcohol with water; remember that less is better," he said.
The cardiologist also cautioned that the holidays can be physically and mentally demanding, advising people to take regular breaks, get enough sleep, and avoid over-scheduling activities.
He underscored the importance of post-holiday health check-ups.
"After the festivities, schedule a health review—blood pressure, blood sugar, cholesterol, and if needed, an ECG. This ensures that any silent damage is detected early and managed promptly," Leachon said.
"Do not ignore chest pain, shortness of breath, or sudden weakness. Seek medical help immediately," he added.
