Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
