During winter, smog and haze in Northern India become severe due to a combination of factors like stubble burning, vehicular emissions, and industrial pollution. The cooler temperatures and stagnant air trap pollutants close to the ground, resulting in dense fog-like conditions that significantly reduce visibility. This worsening air quality poses serious health risks, particularly for respiratory and cardiovascular conditions, as fine particulate matter (PM2.5) levels rise to hazardous levels. Prolonged exposure can lead to chronic diseases, especially among vulnerable groups such as children, the elderly, and those with pre-existing health conditions. The pollution also disrupts daily life by affecting transport, as dense smog leads to flight delays, traffic accidents, and difficulty navigating roads. Additionally, the haze exacerbates environmental issues, harming crops, reducing sunlight, and impacting the region's ecosystems. The situation is compounded by limited wind movement, which hinders the natural dispersion of pollutants. Efforts to combat the crisis, such as controlling stubble burning and improving air quality monitoring, have been slow and often lack enforcement, making the region's winter air quality a pressing concern for both public health and the environment.
