Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
