Note: The heat index, also known as 'real feel' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
