Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
