Note: The heat index, also known as 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 largely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
