Note: The heat index, also known as 'real feel' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
