Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
