The pollution spike during Deepavali affects individuals with pre-existing respiratory conditions, such as asthma and COPD, more severely. However, even healthy individuals may experience airway irritation, coughing, and discomfort due to high concentrations of particulate matter and gases. Long-term exposure to such pollution can lead to chronic respiratory issues and other health complications. Vulnerable groups, including children, older adults, and pregnant women, are at higher risk.
