Winters in general and extreme winters are always a hard time for the heart as the cold weather makes it difficult for the body to maintain the required inner core temperature. Cold weather precipitates vasoconstriction i.e. narrowing of the blood vessels and people with pre-existing conditions like Coronary artery disease, uncontrolled hypertension and diabetes are particularly vulnerable. Reduced physical activity and winter-related weight gain exacerbate these risks. Understanding these dangers is crucial for prevention.
Winter’s chill is more than uncomfortable—it can be life-threatening. Heart and circulatory diseases spike during the colder months, becoming a leading cause of deaths globally. Experts warn that physiological stress, combined with lifestyle changes in winter, significantly increases cardiovascular risks.
Dr Praveen Sadarmin – Consultant Cardiology Adult, Narayana Health City, Bengaluru said, “recognizing early symptoms like chest discomfort, breathlessness, or dizziness should alert people to take appropriate action and seek medical help. Lifestyle adjustments like staying active and indulging in indoor physical activity/exercise will minimise some of these risks. Avoiding walking in the early mornings or very late evenings when the temperature dips will help prevent angina. Access to appropriate medical care and emergency tablets like Sorbitrate in CAD patients can prevent harm. Managing stress, depression (which is common in winter months), moderating unhealthy food intake and increasing physical activity can overcome what could be a potential stressful winter.
Winter can pose unique challenges to heart health, but simple preventive measures can make a significant difference. Staying active is crucial, as regular physical activity enhances blood circulation and helps prevent winter-related weight gain. Indoor exercises such as yoga, light aerobics, or brisk walking are excellent options. Dressing warmly is equally important, as proper clothing prevents heat loss and reduces the heart’s workload; extra care should be taken to keep extremities like hands and feet warm.
Dr. Mahadev Swamy B, Consultant Interventional Cardiologist at SPARSH Hospital, Infantry Road said “Winter is a high-risk period for individuals with cardiovascular issues due to the added burden of respiratory infections. These infections can cause systemic inflammation, increasing the risk of heart attacks and strokes. People should be cautious of symptoms that seem minor but may signal heart trouble, such as fatigue or jaw pain. Preventive strategies like flu vaccinations and maintaining a balanced diet can significantly reduce these risks. Being aware of the connection between infections and heart health is critical for early intervention.”
A balanced diet rich in omega-3 fatty acids supports heart health, while limiting salt and sugar intake helps prevent hypertension and diabetes. Staying hydrated is essential, even in cold weather. Drinking water consistently throughout the day can help mitigate health risk.
Regular health monitoring, including routine checks of blood pressure and cholesterol levels, is vital, especially for individuals with pre-existing conditions. Watch for subtle symptoms like fatigue, shortness of breath, or chest discomfort, and consult a doctor if needed. With proactive care and seasonal adjustments, winter can be a time of wellness and vitality, ensuring your heart remains healthy and strong.
