Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
