Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. 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. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
