As the temperature lowers, the danger of heart-related diseases is on the rise, making winter a tough season for cardiovascular health. Research studies have shown that the risk of heart attack increases up to 53% in winters compared to summers. Such seasonal increase necessitates increased awareness and proactive heart care during the cold seasons.
Cold weather causes constriction of blood vessels that leads to increased blood pressure, forcing the heart to work hard in circulating blood. With every 1°C drop in temperature, the risk of heart attack increases by 2%. Studies also reveal that there are 26-36% more deaths due to heart problems in winter than during summer. In addition, inhalation of cold air may trigger arterial spasms that decrease blood flow to the heart. At the same time, the body’s attempt to produce heat accelerates heart rates that further exert the cardiovascular system.
Dr. Amit Bhushan Sharma, Director and Unit Head – Cardiology – Interventional, Paras Health, Gurugram, explains, “The winter season places unique stress on the cardiovascular system. Cold weather not only increases blood pressure but also makes pre-existing heart conditions more dangerous. Simple steps such as dressing warmly, staying active indoors and monitoring blood pressure regularly can significantly reduce risks. For those with heart conditions, regular check-ups and vigilance are crucial during this time of year.”
To prevent heart problems in winter, experts advise some common measures such as wearing layers to keep the body warm, avoiding sudden exertive activities and opting for light indoor exercises instead of strenuous ones, which can strain the heart too much.
A diet with fruits, vegetables, whole grains, and omega-3s also helps regulate cholesterol and promotes cardiovascular well-being. Blood pressure monitoring and vigilance about warning signs such as chest pain or shortness of breath should be considered among the key steps to preventing complications.
Timely health screenings can also allow people to detect potential problems early and receive appropriate care during the winter months.
As the season unfolds, prioritising heart health and adopting preventive measures can significantly reduce winter-related cardiovascular risks and ensure overall well-being.
