Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
