Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
