Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
