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 important for children.

Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
