The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
