'Layering up warm clothes, mild flu infections among major causes of heart attack in winter'

As winter sets in, the risk of heart attacks tends to increase, posing a seasonal challenge for cardiovascular health. Several factors contribute to this heightened risk during colder months. To mitigate these risks, individuals should prioritize cardiovascular health measures during winter. This includes maintaining regular physical activity, adhering to a heart-healthy diet, staying warm to prevent blood vessel constriction, and getting vaccinated against seasonal infections. Being aware of these seasonal risks and adopting proactive measures can help safeguard heart health during the winter months.

Dr. Bhargava explains: In cold weather, the blood vessels contract and get narrow. This increases the impact on the heart by decreasing the blood supply to the body, which raises metabolic stress. Additionally, it could raise blood pressure. These conditions put undue strain on the heart. It is more difficult for your body to maintain a healthy temperature in cold weather because your body loses heat more quickly. The heart has to pump more heated blood, which puts more load on it.

During winter season we layer ourselves with warm clothing, especially in places where the temperature falls down to a much colder temperature. "Overheating can result from wearing warm clothing and then exercising. If you have heart disease, overheating might cause your blood vessels to suddenly dilate or widen, which can result in hypotension or low blood pressure. If you notice yourself sweating while outside in the cold, you are overheating. If you have heart disease, this sweating should be taken seriously. Discontinue any activity you are performing and head indoors," says Dr. Bhargava.

As per the expert, in extreme cold conditions, people tend to stay indoors which limits physical activity and slows down cardiac circulation. He also talks about the lifestyle changes that accompany the winter season. "Overindulgence in unhealthy food, alcohol, partying, and sleep deprivation during the winter festivities can put a lot of stress on the heart. Also, elevated emotional reactions, if uncontrolled, can lead to cardiac stress," he adds. “Before heading outside, stay away from alcohol. It causes your skin's blood vessels to enlarge, which feels warm to the touch but takes heat away from your vital organs,” he warns.

"Winter is the best time of year to travel for leisure in India. Even though scenery and a relaxed environment can be beneficial to your health, the major change in daily routine and activities can put a strain on your heart," Dr. Bhargava says. If you are travelling make sure you don't miss out on hydration. “Drink a lot of water. Rapid dehydration caused due to cold weather might strain the metabolic system. Consume light, easily digested meals. Be careful not to overindulge in sweets, salty, and oily foods throughout the holiday season and celebrations,” Dr. Bhargava recommends and also suggests avoiding walking more rapidly or engaging in any strenuous physical activity outside in the cold.
