Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
