AIIMS warns cold weather and pollution in Delhi raise heart risks

Cold weather and rising air pollution in Delhi are triggering a surge in heart disease, COPD, and asthma cases, doctors at AIIMS warn. Experts say cold constricts blood vessels, raising blood pressure and the risk of heart attacks. Elderly people and those with comorbidities should avoid cold exposure, monitor blood pressure regularly, and limit outdoor activity when AQI is high.
