Health science

Health science or biomedical science is the applied science dealing with health. There are two approaches to health science: the study and research of the food that we eat and the study and research of health-related issues to understand how humans and other animals function, and the application of that knowledge to improve health and to prevent and cure diseases. Health research builds upon the natural sciences of biology, chemistry, and physics as well as a variety of multidisciplinary fields. Some of the other primarily research-oriented fields that make exceptionally significant contributions to health science are biochemistry, epidemiology, genetics, and pharmacology. A myriad of applied health specializations and professions also endeavor to better understand health, but in addition they try to directly improve the health of individuals and of people in general, as well as of other animals. Some of these are: alternative medicine, biomedical engineering, biotechnology, clinical laboratory science, medicine, nursing, nutrition, pharmacy, public health, psychology, and physical therapy. The provision of services to improve people's health is referred to as health care.
