Heat index values are extremely significant for babies and toddlers. 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. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
