Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
