Heatstroke may follow lengthy activity.Note that heat index values are valued for light wind and location in the shade.

Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity.

Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
