Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air.

Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
