Many governments view occupational health as a social challenge and have formed public organizations to ensure the health and safety of workers. Examples of these include the British Health and Safety Executive and in the United States, the National Institute for Occupational Safety and Health, which conducts research on occupational health and safety, and the Occupational Safety and Health Administration, which handles regulation and policy relating to worker safety and health.
Health psychology, developed in the late 1970s, is its own domain of inquiry. Also called a medical psychologist, the health psychologist helps individuals explore the link between emotions and physical health. The health psychologist also helps physicians and medical professionals understand the emotional effects of a patient’s illness or disease. They practice in the areas of chronic pain management, oncology, physical rehabilitation, addiction treatment, eating disorders, and others. This professional can be found in clinics, hospitals, private practice, and public health agencies. Some also work in corporate settings to promote health and wellness among employees, engaging in workplace policies and decision-making.
Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities". Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living. This opens up many possibilities for health to be taught, strengthened and learned.
