How the Risk of Brain Stroke Increases During Winter

Udaipur: While the winter season may seem comfortable, it can be hazardous to heart and brain health. Cold temperatures can raise blood pressure and thicken the blood, increasing the risk of brain strokes. A stroke occurs when blood flow to the brain is disrupted, either due to a blockage in the arteries (ischemic stroke) or a blood vessel rupture (hemorrhagic stroke). Cold weather causes blood vessels to constrict, forcing the heart to work harder to pump blood, and this increased pressure can lead to a stroke.

Dr. Tarun Mathur, Senior Consultant Neurophysician & Stroke Specialist at Paras Health Udaipur, says, "The risk of stroke increases in winter, especially for patients who already have conditions like high blood pressure. Cold temperatures cause blood vessels to constrict, raising blood pressure and putting more pressure on the heart. Additionally, cold weather causes the blood to thicken, increasing the risk of clot formation. To prevent stroke during winter, it is essential to regularly check your blood pressure and stay active." Dr. Mathur recommends adopting a healthy lifestyle during the colder months, including regular exercise, a balanced diet, and monitoring blood pressure. He also advises limiting alcohol consumption and taking medications regularly.

Studies show that stroke cases tend to rise in winter. Cold weather can also lead to dehydration, which thickens the blood, further increasing the risk of stroke. A decrease in physical activity, weight gain, and elevated cholesterol levels are additional risk factors. Moreover, thickened blood during winter increases the likelihood of clot formation, which often leads to ischemic strokes, the most common type of stroke. Additionally, cold temperatures can cause reduced physical activity, leading to weight gain, increased cholesterol, and higher blood pressure. Dehydration in winter also thickens the blood, further elevating the stroke risk.

Stroke symptoms are often ignored, but early recognition can save lives. Key symptoms of a stroke include a drooping face on one side, weakness in the arm, and difficulty speaking. If any of these signs appear, immediately call emergency services.
