, but also as a weapon. The struggle for existence and survival made people cling to life by hook or by crook, adjust to any adversity. No matter how heavy they are. Feel free to face the dangers.
The desire to realize the seemingly impossible, pervading the entire history of mankind, helps to understand the incredible efforts made by people in different parts of the world in order to adapt to harsh natural conditions. Man has always had the ability to adapt to natural and artificial environments. From the primitive hunters who went out to the beast with a stone ax in their hands, to the space travelers of our century.
For people whose life is constantly fraught with dangers, preliminary preparation is very important. Both physical and psychological. Rescuers, military personnel of many military branches, tourists going on long routes, researchers, must necessarily go through the preliminary adaptation process. As a result, previously absent resistance to the conditions of polar cold, sultry deserts or lack of oxygen at mountain altitudes, fresh water in the salt sea is acquired.
Adapting to environmental conditions.
People who have undergone full adaptation have a chance not only to save life itself, but also to solve problems that were previously unsolvable. The adaptation process is very complex and multi-stage. At its first stage, the stage of adaptation to any new factor, the body is close to the maximum of its capabilities. However, it solves the arisen problem far from completely.
After some time, if a person does not die, and the factor requiring adaptation continues to operate, the possibilities of a living system increase. The extreme, or urgent, stage of the process is being replaced by a stage of effective and sustainable adaptation. This transformation is the nodal link of the whole process. Its effects are often astounding..
Most people put in extreme situations, from which there is no way out, do not die, but acquire one degree or another of fitness for them. How they save their lives until better times.
In the human social environment, the same pattern applies. Over a relatively short period of its history, mankind has gone through periods of slavery, serfdom, and world wars. But at the same time it did not degrade, demonstrating the high efficiency of adaptation to extreme situations.
Of course, the price of such an adaptation is unreasonably high. But these indisputable facts inevitably lead to the conclusion that the body must have sufficiently effective specialized mechanisms that limit the stress response and prevent stress damage. And most importantly, to preserve life and health.
