Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
