Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
