Heat index values are highly critical 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
