Note: The heat index, also known as 'felt air temperature' or 'real feel', 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 the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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 the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
