This Shift Provides Both Immunity Suppression, And Strengthening

This shift provides both immunity suppression, and strengthening of coagulability of blood, and, at last, increase of production of cholesterol - the important structural part of a cage without which process of cellular division is broken. All these changes occur at each emotional stress. For example, at students during examinations the cholesterol maintenance in blood - one of primary factors of development of an atherosclerosis too increases. But after all the life forces to take examinations at all only within the precincts of institute. So, frequent or long excitements, creating a false situation of protection, form typical illness of ageing - an atherosclerosis. But all negative consequences of stress as though in the future, and now, in a phase of direct restoration, everything that was described above, it is useful. Special the hormone directly from arrives in a hypophysis and therefrom in blood, detaining allocation of water by kidneys and to those helping restoration of the lost blood.

Thereby, Being Protected From External Causes Of Death,

Thereby, being protected from external causes of death, the organism not only does it by illnesses of adaptation, but also accelerates natural process of ageing. Here thus a hardship and grieves reduces days of a life. It is necessary to add still that increase a threshold at stress is caused as follows. When the cat and a dog have noticed each other, the signals estimating this event, from the central nervous system directing in system and in , stir up its activity. But any activity in system of nervous cages is connected with an expenditure of intermediaries - a nervous impulse. All vegetative system is subdivided on mutually counterbalanced two, antagonistic department - sympathetic and parasympathetic nervous system. According to it there are two groups of mediatorov-intermediaries. It is conditionally possible to name them With - for sympathetic impulses and P-mediatory - for parasympathetic. Group S-mediatorov concern and norad-renalin - the substances structurally very close to to a hormone of alarm - to adrenaline; group P-media-torov includes and connections close to it ( ).
