In today’s lifestyle it is unthinkable to have a day without coming into contact with electronic devices such as cell phones, laptops, tablets, Televisions and now LEDs. In the whole world people are relying heavily on these technological tools for entertainment and for communication with friends, family, and at school and work. All these devices emit Electro-Magnetic Radiations (EMR) which are harmful for human beings as they cause many harmful effects including Cancer. Data gathered from 13 participating countries was pooled and analyzed by the International Agency for Research on Cancer (IARC), to determine whether there were any links between use of mobile phones and head and neck cancers in adults. Based largely on these data, IARC has now classified electromagnetic radiofrequency fields as possibly carcinogenic to humans (Group 2B), a category in which harmful pesticide like DDT has been kept. Thus, we need a solution which can be imbibed in our day to day lives to reduce EMR level at our residences and workplace. Yagya is a non-conventional solution suggested in Indian scriptures to save from harmful cosmic waves. Hence, in the present study, Yagya was conducted as an intervention to find its impact on the indoor EMR flux. Five case studies were performed in NCR Delhi. It was observed that after the performance of Yagya there was a significant decrease in the indoor EMR level indicating a utility of Yagya as non-conventional solution for reducing indoor EMR level.
