Health science is the branch of science focused on health, and it includes many subdisciplines. There are two approaches to health science: the study and
research of the human body and health-related issues to understand how humans (and animals) function, and the application of that knowledge to improve health and to prevent and cure
diseases.
[edit] Sources
Health research builds primarily on the basic sciences of
biology,
chemistry, and
physics as well as a variety of multidisciplinary fields (for example
medical sociology). Some of the other primarily research-oriented fields that make exceptionally significant contributions to health science are
biochemistry,
epidemiology, and
genetics.
[edit] Application
Applied health sciences also endeavor to better understand health, but in addition they try to directly improve it. Some of these are:
health education,
biomedical engineering,
biotechnology,
nursing,
nutrition,
pharmacology,
pharmacy,
public health (
see above),
social work,
psychology,
physical therapy, and
medicine. The provision of services to maintain or improve people's health is referred to as health care (
see above).
