Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 extremely vital to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
