Prolonged activity may induce heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature.

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