Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
