Heat index

It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
