Heat index

Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
