For many people, winter feels like a season of warm clothes, hot food and cosy evenings. But behind this comforting picture lies a lesser-known reality—the cold months can be surprisingly tough on the heart. A doctor from Bengaluru recalls how, years ago, living in Jaipur made him notice how naturally people prepared for winter. Warm clothes came out after Diwali and stayed till Holi, almost like a rhythm woven into everyday life. That simple habit, he says, also reflects how important it is to protect the body from harsh temperatures.
Winter doesn’t just bring the usual coughs and colds. It also increases the chances of serious heart problems such as heart attacks, strokes and the worsening of existing conditions like heart failure or irregular heartbeat. The cold affects the body in ways many people don’t realise.
When temperatures drop, blood vessels tighten, making it harder for blood to flow. The body responds by raising blood pressure, a change that can be dangerous for older adults, diabetics, those with hypertension and people with existing heart issues. Cold weather also makes blood more likely to clot, which increases the risk of sudden cardiac events.
Lifestyle changes during winter play a role too. Many people move less, eat richer food and drink more alcohol during the season—all factors that can strain the heart. Viral infections like influenza, which are common in winter, also contribute to heart complications, especially in older individuals.
Doctors emphasise that prevention starts with simple habits. Dressing warmly, especially when stepping outdoors, can protect the body from sudden temperature drops. People with diabetes or hypertension should monitor their health closely and take their medications without fail. Anyone on blood thinners must avoid skipping doses and maintain regular movement to prevent clotting.
A balanced diet, regular exercise and limited alcohol intake are essential during winter. Avoiding overeating—especially sugary, refined or high-calorie foods—can help keep the heart healthier through the colder months.
Winter may be beautiful, but it demands care. With a little awareness and preparation, the season can stay pleasant without putting the heart at undue risk.
