Health is a condition of mental, physical and social well being where infirmity and disease are absent. Various definitions have been employed over the years for various medical purposes. Generally it is understood to be the state of complete well being with no emotional or psychological problems.
The definition has been evolved taking into consideration current knowledge about the factors that promote ill health conditions as well as the effects that these factors can have on the physical and mental well-being of an individual. Factors that contribute to poor well-being include stress, nutrient deficiency, under nutrition, anxiety, inadequate sleep, toxins, smoking, occupational exposure to harmful chemicals, psychosocial problems, environmental risks and food intolerance. Other possible factors that may be taken into consideration are the following: the quality of life offered by work (work related feeling of well-being), social support, economic status, level of independence and perceived control over one’s life.
The advancement of science has contributed significantly to the better understanding of disease processes and their biological basis. The discipline of health science has developed various concepts over the years that reflect on the physical and mental aspects of the human body and mind. The major objective of this branch of medical science is to develop preventive measures for the prevention of diseases and injury that can lead to severe consequences. The branch of health science aims to maintain the standard of living through research and teaching methods that will foster the development of a healthy society by eliminating physical and mental disorders. There are five main fields of health science that are bioorganic chemistry, epidemiology, clinical pharmacology, primary care, and psychosocial sciences. These fields are further classified into five basic areas: microbiology, nutrition, neurobiology, physiology and psychology.
The goal of health is the well being of the individual through optimal levels of physical and mental wellness. This can be attained through a combination of diet, exercise, psychological counseling, and a lifestyle that support physical activity and relaxation. Prevention of illness and injury is achieved by promoting a healthier environment.

The goal is to promote physical and mental wellness through a balanced system of systems and actions.
Psychosocial well being is the tendency to interact with other people, including emotions, relationships, work, and other aspects of daily life.
