Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
