Note: The heat index, also known as 'apparent temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
