Severe winter air pollution in northern India poses significant health risks, particularly for residents in urban areas like Delhi and the Indo-Gangetic Plain. High AQI levels can exacerbate respiratory and cardiovascular conditions, especially among vulnerable populations such as children, the elderly, and those with pre-existing health issues. During extreme pollution episodes, authorities often implement emergency measures, including halting construction activities, restricting industrial operations, and limiting vehicle traffic. These interventions, while necessary, can disrupt daily life and economic activities, highlighting the need for better seasonal planning and proactive measures.
