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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
