Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
