Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. 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 process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
