Severe air pollution poses significant health risks, particularly to individuals with pre-existing conditions, as noted by the CPCB. The high levels of PM2.5 particles in the air can lead to respiratory issues, cardiovascular problems, and other health complications. The situation is exacerbated by stubble burning and the use of firecrackers during Deepavali, which further deteriorates air quality. Vulnerable groups, including children, the elderly, and those with respiratory conditions, are at heightened risk.
