Public Health Promotion
Health, as defined by the World Health Organization, is a condition that “is not only the absence of illness and infirmity, but the relative protection against disease and disability.” A number of definitions have also been used over the years for various purposes. In defining health, it usually involves four key elements: physical, psychological, social and cultural. Each of these aspects is related to what the individual’s needs and capabilities are in relation to achieving these goals. The other three are also related to these other components in that the ability to achieve goals in each area is directly influenced by the other two.
The concepts of health and illness are interrelated in that the former refers to the absence of disease or death while the latter pertains to a state of normal bodily function. The former involves preventing illness while the latter covers the after affects (or symptoms) of an illness. The concepts of health and illness are also related to those aspects of life that are behavioral. For example, a person who stays healthy may be able to avoid certain behaviors (like smoking and drinking) that put their body at risk of illness.
Prevention is key when it comes to health promotion. Although the best way to prevent diseases is to prevent the conditions that already exist, people can take certain measures to avoid future illness. In terms of mental, emotional, and physical health, the following general concepts are useful: A sense of personal responsibility; proper nutrition; regular exercise; and getting adequate sleep. These general concepts are interrelated and are interdependent upon one another. Proper nutrition is very important to a healthy mind and body and regular exercise promotes a sense of physical well being.
