With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 quite important for children.

Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
