Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
