Fatigue in children

Fatigue in children has some features associated with anatomical and physiological properties of the child's body. So, the smaller the child, the faster he develops an exhaustion. The infant wakefulness during 1,5-2 hours leads to fatigue even without active work. Further fatigue occurs as a result of active work as muscle (the game)and mental (lessons). It should also be borne in mind that monotonous activities extraordinarily quickly causes fatigue in children. Know, then, that in the childhood the processes of excitation prevail over the processes of inhibition. So long braking the child easily leads to fatigue. An example is fatigue generated by braking the motor areas while sitting behind the Desk in school.
The appearance of fatigue contribute to reducing the duration of night sleep, impaired daytime sleep (early switch to a single sleep), lack of exposure to fresh air. Incorrect alternation of work and rest also causes fatigue children. Fatigue can easily result in the long monotonous classes, excessive entertainment child, persistent requests adults to be in the same position, to sit still and don't move.
Fatigue in children is accompanied by the weakening of the most difficult inhibitory processes: attenuated differentiation, falls accuracy, deteriorating attention, comes motor anxiety. Further development of fatigue leads to a protective inhibition, which is manifested by the increase of the threshold visual, auditory, skin analyzers; younger children braking covers the entire cerebral cortex and cause sleep.
Children of school age with mental activities associated with long practice, especially when training simultaneously in two schools, in school and in addition a few circles may experience fatigue. Contributing factors are also the rhythm of work and rest, lack of exposure to fresh air, sleep deprivation. External signs of fatigue appear as pale mucous membranes and skin, in a relaxed pose, uncertain and sluggish movements, sometimes there is a tremor of the hands, sometimes motor anxiety. The pace of work and school becomes slow, children are not interested in practice, irritable, easily excitable, they increased the number of errors, attention and concentration is reduced, reduced mental performance, some appear crying.
To prevent fatigue is necessary to establish mode of day of the child, to exclude completely the lack of sleep, reduce stress, to organize a change of mental work and rest, to increase the exposure to fresh air.
In children of preschool age of compulsory classes should continue uninterrupted no more than 15-20 minutes avoid repetitive activities, and in the elementary grades to change activities even during one lesson.
It is necessary to alternate the intellectual work with physical activity after school to give children a sufficiently long rest.
