Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
