Delhi's Air: Experts Warn of Lasting Lung Damage

Delhi's annual air pollution spike ahead of winter is a serious health concern. Dr. Saurabh Mittal from AIIMS highlights that prolonged exposure to toxic air leads to cumulative damage in the respiratory and cardiovascular systems, impacting individuals with pre-existing conditions and the elderly most severely. Fine particulate matter, such as PM2.5, can bypass natural filters, reaching deep into the lungs and potentially entering the bloodstream. This ingress triggers inflammation and oxidative stress, contributing to issues like endothelial dysfunction and arterial stiffness. The consequences are particularly dire for children, whose lung development can be permanently impaired, leading to reduced lung capacity and increased susceptibility to lifelong respiratory problems. Medical experts advise minimizing outdoor exposure during severe pollution episodes by staying indoors with closed windows and using properly fitted N95 masks when venturing outside. Air purifiers equipped with HEPA filters can help mitigate indoor pollution.
