Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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 human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
