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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
