Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature.

Heat index values are extremely significant for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
