Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
