Health can be viewed as the presence or absence of disease or medically measured risk factors in an individual. However, a broader view of health would include physical, mental and psychological health. Thus, one way of defining health is the absence of any disease or impairment. The second is that health is a state that allows the individual to cope with all demands of daily life adequately. Finally, another definition states that health is a state of balance. An individual has established an equilibrium within himself and between himself and his social and physical environment.
