Note: The heat index, also known as 'felt air temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
