Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
