Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
