In the course of evolutionary development of man was prepared by nature to perceive the various influences of the external world, to establish permanent contacts with changing it processes.
For thousands of years developed a relevant biological rhythms in different functional systems of the body, and these rhythms are changed according to the changes of the natural environment in which it was located. On the basis of scientific data, especially the XX century, the century of scientific and technical progress, it is proved that a living cell, with its complex biological structure and metabolism there are over 3 billion years. Biological restructuring of the simplest organisms and animals at various stages of development went on a fundamentally new type of devices in comparison with the initial stage of their occurrence.
Every person at birth carries the final results of biosocial evolution. Especially clearly this evolution can be traced in unusual conditions of life of the most ancient man. It is established, for example, that 8 million years ago rampitec was the most ancient human ancestor [Dubinin, 1977].
It is known that modern man - Homo sapiens appeared only 30-40 thousand years ago and the progress of its development began to be determined by social reasons.
Mighty factor in the development of personality was and is the work. In the process of social labor was formed man - his mind, his talent, emotional, health, etc. Important role in this process played the second signal system - to-speech engine, with which in the cortex summarizes certain specific stimuli outside world, affecting mental activity of the person and change the function responsive its systems. Australopithecus (South monkey) lived about 2.6 million years ago and began to walk on two legs because the environment has changed outside world - the landscape, the climate, the location of the seas and oceans. So tread Australopithecus is considered from the standpoint of its adjustment to changes of the outside world. Brain volume Australopithecus was equal to 500 cm3. The upright man, Homo erectus - this volume reached 1250 cm3. When direct ancestors of this person (200 thousand years ago) the amount of brain mass was 1500 cm -3 [Dubinin, 1977].
People were purposefully created instruments of production was affected by them on the nature and took part in its transformation. This long and difficult way of development is even more increased the relationship of man and nature.
The human environment is often viewed as the natural environment, which held its evolution. Therefore, S. P. Botkin [1888], then and I. P. Pavlov [1908] at definition of the term "disease" came from the fact that its meaning but essentially lies in the imbalance between the external and internal conditions of human life. Meanwhile, people in their mutual relations are creating a lot of problems, it is often more difficult than putting them to nature. This is particularly important now, in the age of scientific and technological progress.
Physical and mental health or ill health are largely determined by the role in a person's life is played by industrial relations, family, friends, coworkers and social conditions of life of society. The world health organization (who) believes that health is not merely the absence of disease or infirmity, but a state of complete physical, mental and social well-being. This formulation, however, does not reveal the meaning of illness, mechanism of development and does not specify how to maintain health.
The Minister of health of the USSR S. P. a Burenkov briefly, but rather concisely defined the ways of health: "Improving the health of the people consists of everyday organizational work of a great many specific cases". These cases should be directed to the development of biomedical and social measures required to promote health of the people.
