Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
