Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
