Heat index

Given the heat index, its values are aligned with shaded sites and gentle winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
