Srinagar, Dec 14: The incidence of heart attacks and strokes doubles in Kashmir during winter as exposure to cold constricts blood vessels, forcing the heart to work harder, experts warn.
Dr Irfan, a cardiologist at GMC Srinagar told that cold weather significantly impacts cardiovascular health, which leads to a rise in heart attacks and strokes during the winter months.
“The incidence of heart attacks and strokes more than doubles in Kashmir during winters compared to summer,” he said. “Exposure to cold causes blood vessels to constrict—a process known as vasoconstriction—which elevates blood pressure and forces the heart to work harder to circulate blood throughout the body. This added strain exacerbates existing heart conditions and increases the risk of cardiovascular events.”

He explained that colder temperatures thicken the blood and make it more prone to clotting, which heightens the risk of heart attacks and strokes. “People with underlying medical conditions like diabetes, hypertension and smokers are more vulnerable as they are usually immunocompromised,” Dr Irfan said. “In winter, increased tea consumption can elevate blood sugar levels, a major risk factor for heart attacks and strokes.”
Dr Irfan also highlighted that many heart attack patients are misdiagnosed and treated for other illnesses, complicating their condition further.
Dr Javid, another cardiologist, advised people to take extra precautions in winter to prevent heart attacks and strokes. He recommended dressing in layers, using scarves, gloves, and hats to maintain body warmth, keeping homes well-heated and avoiding prolonged exposure to the cold.
The doctor urged people to exercise indoors if it is too cold outside and to avoid strenuous outdoor activities, such as heavy shovelling, in extreme cold. “To reduce risks, people should consume a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins while limiting salt, sugar, and saturated fats,” he added.
Doctors advised staying hydrated to prevent blood thickening and knowing the symptoms of heart attacks (e.g., chest pain, shortness of breath) and strokes (e.g., face drooping, arm weakness, slurred speech) to seek immediate medical attention when needed.
