In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. 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.
