Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
