WHO Definition of Health: Physical, Mental & Social Well-being

The World Health Organization (WHO) defines health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". This definition emphasizes that health is not simply the absence of illness, but also includes mental and social well-being. It also recognizes that health is a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities.
