Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
