Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
