Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat.
