Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
