Heat index

Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 are primarily vital for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
