Health is a condition of mental, physical and emotional well being where infirmity and illness are absent. It is a state when all the three components of health are present: vitality, health, and satisfaction. Vitality is synonymous with life giving energy. Health is the state of complete well being, having no disabilities and no complaints of pain or discomfort.
The three components of health are psychology, physiology and public health. The three interrelated aspects of psychology include psychology as the science of mental health, physiology the science of physical health and public health the science of general health. These aspects combine to form the diagnosis of psychological well-being, physical health and general well-being.
The three aspects of psychology are affective psychology, cognitive psychology and attitude toward health. Attitude toward health and disease prevention provides information on how people view the relationship between behavior, environment, genes and behavior and disease. It provides a scientific background to support the cause and effect relationship between these aspects and health. This information on the relationship provides guidelines for health promotion and disease prevention.
There are two parts to this science of psychology: psychology and psychiatry. The other aspect of psychology concerns the understanding of brain processes and the human brain. Neuropsychologists provide information on how the human mind works. They also study the disorders and treat them. They provide information on the use of medication and other methods of treating mental disorders.
Public health experts deal with the general problems related to health and educate people about them. They conduct research and distribute information on preventing physical health and mental health. The objective of the public health specialist is to decrease the incidence and prevalence of chronic and infectious diseases that have high costs and high mortality rates.
