Note: The heat index, also known as 'real feel' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
