Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
