Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception.

Heat index values are quite important 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 temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
