Impact of the climate of the Extreme North and education conditions on young school children

The scientifically grounded sound regimen is required for schoolchildren, younger ones in particular, who most experience unfavourable environmental factors. Particular emphasis should be laid on the regulation of educational burden at primary school since the irrational distribution of classes leads to the development of fatigue mainly in young schoolchildren and hence to lower working capacities and poor comprehensibility. The investigations have supported the earlier data that the children show the strained body's functional status which is deteriorated by the influence of educational burden. The findings suggest that there is a need to elaborate scientifically grounded preventive measures to minimize the unfavourable influence of environmental factors in the North and to develop and implement the means that enhance adaptive capabilities of the children there.
