This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children.

Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
