Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
