Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
