Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees.
