Note: The heat index, also known as 'apparent temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
