Different Areas of Study Related to Occupational Health

Health, as defined by the World Health Organization, is “the condition of being fit and healthy.” Various definitions have been used over time for various purposes. In common usage, however, the word health has become much broader and now includes the prevention and treatment of many diseases and bodily disorders. It also includes the ability to lead a productive and happy life.


The field of public health has been greatly affected by developments in the sciences over the last century. Public health is concerned with the overall well being of the population as a whole. This is an area of study that encompasses a wide range of topics, such as nutrition, child health, infectious diseases, and reproductive health. It also monitors the health of individuals at the community level, looking at how diseases are affecting the local population and how to control and prevent them.

One branch of public health that has had a profound impact on the world of medicine is the psychology of health. Psychology studies both the physical and mental aspects of human beings. It examines causes, treatments, and prevention of disease in both industrialized and underdeveloped countries. Much of this research is done through epidemiological and experimental techniques.

Mental health services deal mainly with mood disorders and depression. Treatment may focus on improving the patient’s coping skills and reducing stress. They may also refer patients to other appropriate venues, such as the appropriate centers for mental health care, where they can receive psychological counseling as well as receiving treatment for their chronic diseases. Mental health services are a large part of public health services.

Prevention of physical disease is another major branch of psychology. There are many physical conditions that affect people on a day-to-day basis, such as cancer and heart disease. Serious psychological disorders can result in physical illnesses, such as depression and schizophrenia. Public health experts have recognized the link between physical and mental health. This is why they often work closely with healthcare providers to create prevention programs and provide information on good health practices.

Occupational psychology is related to occupational health care, which deals with the working conditions of people who produce goods or services. Studies show that workers who are emotionally healthy are happier and perform better at their jobs. This includes individuals who perform physically demanding jobs, such as operating heavy equipment or industrial machinery. As more industries continue to turn to highly trained professionals, mental health professionals are sure to find a steady increase in employment opportunities.
