Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
