Abstract
Physiologists describe numerous cases of hypermobilization of the functional state of humans in extreme conditions, but the causes and mechanisms of this phenomenon have never been analyzed. We found that the organism can transfer (or not transfer) to a new level of homeostatic regulation during autogenous stress. This level is characterized by an upward shift of the temperature homeostasis by 1.5°, increase in the physical and mental work capacity (by 15% or more), and general hypermobilization of the functional state, which does not exceed the physiological norm. This hypermobilization level, which increases the survival capacity in dangerous conditions, seems to be an endogenous but inhibited program that formed in the evolutionary process and is only used in extreme conditions.
