Since time immemorial man has been familiar with the disease, trying to recover and escape from the pain and trying to stay healthy. In accordance with the development of human civilization at that time, then attempt to recover from illness and to stay healthy is done in various ways. Therefore, the method and the different ways it is different also from a single course of treatment with other places.

Developing health science of knowledge known to man. Knowledge can be obtained from various sources, among others: the senses, the mind, and intuition. When compared between knowledge and science there is a noticeable difference. Knowledge is all that is known by human beings without regard to the knowledge of right and wrong, whereas science only restrict the right knowledge.

True knowledge is knowledge that has been verified by the scientific method. Well, because human beings want to be free of the disease, then they began to study or examine how to keep healthy people can always live. By using the ability to think rationally on the basis of knowledge, attracting people to study health science that became known as an expert health sciences.
Definition and Development of Health Sciences
The experts then conduct health science studies are observational and experimental through observation and measurement of parameters such as the health of hemoglobin levels in the blood, the content of bacteria in drinking water, vitamin content in food and so on. Based on accurate data, along with descriptive explanations analysis it will obtain the facts which are then used to formulate the concepts in the health sciences.

When we compare the views of people in ancient times by now about the disease, were quite different. In the past people thought that leprosy, for example, is a disease of the curse of God. They also consider that malaria is caused by bad air (mala = bad; aria = air).

Both of these examples illustrate to us that because there is the development of science, the first view of the disease are less precise, so overcome was less precise. For example, to search for a cure to a disease, many of them went to the shaman, warlock, priest, cleric and several other efforts that generally for a specific disease does not produce satisfactory results.

Today we see, that people are constantly trying to find and investigate the causes of the onset of a disease. Thanks to advances in science and technology, particularly in the field of medical technology, people finally know exactly that leprosy is caused by bacteria, not because of the curse of God. Similarly, malaria is not caused by bad air, but is caused by germs that infect the human body through the bite of the Anopheles mosquito. Having in mind that the cause of malaria is a germ that is spread by Anopheles mosquitoes, then the efforts of man is how to eradicate the mosquito Anopheles, and seek healing of the disease. Now people already know that malaria is drug quinine.

From the foregoing, it is clear that the progress made in the field of medicine or health could not be separated from the progress of the sciences that support, especially biology. By mastering the branches of biology such as anatomy, physiology, histology, microbiology, zoology and so on, the doctors are able to arrange for the proper healing of an illness. Even so the rapid progress made in the field of medicine, to the extent that most complex diseases can already be addressed, such as a tumor, cancer, heart disease, neurological diseases, kidney, and so on. Operation, today no longer be a scary thing.

Object and Field Studies Health Sciences

In accordance with the focus areas of the study were studied and the nature of the problem, the health sciences in its development can be grouped into:

1. Personal hygiene (personal health) are focus areas of study are individuals (personal).
2. Studies of public health (public health) are focus areas of study of human groups in society. Both the nature of science has finally evolved into each branch of science itself.
