Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. 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. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
