Persistent activity might trigger heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees.

Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
