Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. 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. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
