(WHO, 1948) defines health

The World Health Organization (WHO, 1948) defines health as a "state of complete physical, mental and social wellbeing and not merely the absence of disease or infirmity". Thus, the World Health Organization (WHO) has very clearly indicated that the absence of disease is not enough for health. This, definition emphasizes on positive and negative dimensions of health. Negative health or ill health has a subjective component expressed in the concept of illness and discomforts and an objective component express in concept of disease, injury, handicap or deformity. Positive health has two components: wellbeing and fitness. This state entails an appropriate balance of the physical, mental, social ingredients. Fitness can be considered as the objective physical components, where as, wellbeing can indicate the psychosocial component of positive health.
