Heat index readings emphasize conditions of light breezes and shaded spots. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
