Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
