Heat index values hold particular importance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
