Examining Vedic Yajna's Effects on the AQI of India in the Second Wave of the COVID-19 Pandemic: An Healthcare 4.0 Concept for Smart Cities 5.0

This paper depicts Vedic science importance in reducing AQI level and betterment of life with use of Indian Vedic ritual Yajna and Havan. The dataset collected here supports the facts and scientifically proves the proposed analysis. The Central Pollution Control Board (CPCB) and the author's team have collected data through installed sensors in different areas. The presented analysis includes experiments in constrained environments as well as open environments. The sensors have been installed to give their output regarding concentration levels of PM2.5, PM10, SO2, NO2 and CO2 in air at every 30 minutes and a dataset of the last four months has been collected. On the basis of pollutants in the environment before and after the Yajna activity, the analysis was done and the graphical depictions verify that the pollution level decreased after the Havan. Yajna activity is an alternative tool to solve the problem of air pollution on an individual as well as community level. The ingredients and material used in Havan as samagri are easily available and are in reach of common man.
