As the winter season approaches, doctors are warning of a seasonal spike in brain stroke cases. According to neurologists, stroke incidences increase by 5–10% during the colder months, with around 35 people requiring emergency treatment for stroke every day. Experts attribute this rise to multiple factors, including sedentary lifestyles, stress, high blood pressure, diabetes, and elevated cholesterol levels. They emphasise that timely treatment and lifestyle modifications can significantly reduce the risk.
Cold weather leads to the constriction of blood vessels and thicker blood flow, increasing the likelihood of clot formation that can cause a stroke, says Dr. Sucheta Mudgerikar, Senior Consultant Neurologist at Apollo Hospitals, Ahmedabad, She adds that reduced physical activity, changes in diet (especially an increase in fatty foods), and alcohol consumption during winter can further heighten the risk.
Doctors also highlight that stroke cases are rising even among younger individuals. Nearly 4 out of every 10 patients are below 50 years of age, which is a concerning trend. According to the National Centre for Disease Informatics and Research (NCDIR), India reports over 1.6 million new stroke cases annually.
“Stroke can affect anyone, regardless of age. If you notice symptoms, seek immediate medical attention,” said Dr Devashish Vyas, an interventional neurologist from Ahmedabad. “The first 60 minutes — known as the golden hour — are critical. Treatments like clotbusting drugs and mechanical thrombectomy can restore blood flow and minimise brain damage if done in time.”
Doctors advise people that early medical intervention greatly improves recovery outcomes. It is considered important to monitor blood pressure regularly, maintain physical activity, eat a balanced diet, and avoid smoking and excessive alcohol, both of which increase blood viscosity and strain blood vessels.
As temperatures drop, experts urge everyone — especially those with underlying conditions — to stay active, stay warm, and stay alert to stroke symptoms.
