Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
