In common usage and medicine, health, Conscious according to the World Health Organization, is “a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity”. A variety of definitions have been used for different purposes over time. Health concious can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health concious are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders
In general, the context in which an individual lives is of great importance for both his health status and quality of life. It is increasingly recognized that health concious is maintained and improved not only through the advancement and application of health science, but also through the efforts and intelligent lifestyle choices of the individual and society. According to the World Health Organization, the main determinants of health include the social and economic environment, the physical environment, and the person’s individual characteristics and behaviors..
