Why heart attacks spike during Christmas and New Year: Cardiologist shares key warning signs

Why do heart attacks rise during the festive season?

Cardiologists point to a combination of behavioural and environmental triggers that make the holidays a risky period for heart health:

• Overindulgence

People tend to eat richer meals, drink more alcohol and reduce physical activity when on holiday. This sudden shift in routine can put additional strain on the heart.

• Emotional and financial stress

Although the festive season is associated with joy, it also brings pressure — from travel plans and family obligations to financial concerns. Increased stress hormones can elevate heart attack risk.

• Cold weather

Winter temperatures can cause blood vessels to constrict. This raises blood pressure and increases the likelihood of plaque rupture, which can lead to a heart attack.

• Delayed medical attention

Many people choose to postpone doctor visits until after the holidays. This delay often results in late diagnosis and poorer outcomes in cardiac emergencies.

How to protect yourself this festive season

Dr London recommends simple, proactive steps to reduce your risk:

• Keep moving

Regular physical activity helps offset dietary excesses. Even a brisk walk can make a difference. “Movement is medicine,” he said.

• Take your medication on time

For those already on heart medication, consistency is crucial. Set reminders to ensure you do not miss doses during travel or celebrations.

• Prioritise rest and mindfulness

Adequate sleep supports recovery and helps regulate stress. Incorporating short meditation or breathing exercises can also ease festive-season strain.

• Never ignore symptoms

Chest discomfort, unusual fatigue, breathlessness or nausea should never be dismissed. Seek immediate medical help. As Dr London emphasised, acting quickly can save heart muscle and improve survival.
