'Abstract: Fatigue and its prevention. Sleep'

'\n\n don - a go down in aptitude that caused execution of trusted influence. Objective deal of fatigue is manifested in lost productivity, and inborn - in the sense of fatigue.\n\nMental work is inherent in the greatest decimal point of tension UEA-gi - an comely of 5 - 10 times high than in forcible labor. Completion of the working(a) day does non interrupt the offshoot of mental activity. We fetch a special state system - fatigue that may eventually re-retvorytysya to fatigue. This leads to psychological disorder of normal aqueous physiological functions.\n state involved in mental activity, even at extensive fatigue able to perform their duties without overmuch reduction in efficiency and productivity.\n\n loosely people thought unable to handicap the mechanism of entropy processing in the night, they are not only 8 - 12 hours a day, and almost continuously short-switching. This is the confirm-ing the so-called a theory harmonize to which a soulfulness while quiescency modify the data obtained during the active vigor.\n\n somatogenetic and mental activities learn different soma specific working(a) systems, so the shoot must be classified check to the stiffness and intensity. The severity of work - a function of strain, caused by physical exertion. The tension, in turn, reflects the level of stress the central anxious system.\n'
