Note: The heat index, also known as 'apparent temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
