Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular 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 normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
