Persistent activity could result in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement.

Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children.

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