ABSTRACT

The foremost objective of Ayurveda is the preservation of health and the prevention of diseases, rather than merely their treatment. For achieving this goal, the concept of Vy?dhik?amatva (immunity) has been given central importance in Ayurvedic literature. However, this significant concept remained largely underexplored and neglected for a long period, particularly in the modern era, and only gained renewed attention after the propagation of immunization programs by the Government of India in the post-independence period. It was during this time that the idea of immunity came into academic focus and gradually found a place in the syllabus of Ayurvedic education. The present study seeks to critically re-explore and re-establish the ?yurvedokta (classical Ayurvedic) concept of Vy?dhik?amatva in the context of contemporary preventive pediatrics. Ancient Ayurvedic texts provide a clear and comprehensive understanding of immunity, correlating it not only with physical constitution but also with lifestyle factors such as daily regimen (Dinacharya), seasonal regimen (Ritucharya), diet (?h?ra), emotional stability, and psychological well-being. Unlike modern biomedical approaches that often limit immunity to cellular and humoral responses, Ayurveda presents a holistic perspective wherein physical, mental, and spiritual domains are considered equally significant in maintaining defense against disease. According to Ayurvedic principles, several key factors are indispensable for optimal immune functioning. These include Agni (digestive and metabolic power), ?h?ra (wholesome diet), Nidr? (adequate sleep), Vyay?ma (regular exercise), Sattva (mental stability and emotional balance), and Ras?yana (rejuvenative therapies). Each of these factors contributes to the promotion of Bala (strength), preservation of Ojas (vital essence), and enhancement of resistance to diseases. In the present work, these determinants of immunity have been systematically compiled from classical Ayurvedic texts and interpreted in the light of modern scientific evidence, thereby providing a bridge between traditional wisdom and contemporary research.
