Data suggests that the heat index is set for environments in shade and with a light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
